Tips To Look After Your Microscope from Experts At BMS

Commonly and extensively used in all different types of labs across the world, microscopes are used to view everything from plant cells to mineral samples, and allow you to observe items that are too small for the naked eye. This kind of device is integral for studying structures, cells, and microorganisms in both diagnostics and research applications.

There are several kinds of microscope, but at SciChem, we only work with the very best microscope manufacturers, including BMS. They offer a wide range of microscopes for both professional use and hobbyists, and they are specialists in the field.

In this article, the experts at BMS have shared their top tips for looking after your microscope.

Take Care of Lenses

The lens is the most critical part of a microscope, and the objective lens must be lowered in order to adjust the view focus. One of the most common issues we see with this equipment is damage to the lenses, so proper care and attention must be taken to keep them in top condition.

When viewing a slide, make sure the objective lens doesn’t lower too much and touch the base. Lenses touching the slides can cause damage such as scuffs and scratches, making them unusable. It is also important to take care to keep lenses as clean as possible.

They are notoriously difficult to clean when they become dirty, so be careful to avoid touching the lenses when using or moving the microscope.

Avoid Improper Handling

The way you handle your microscope will play an important role in the lifespan of your equipment. Improper handling is often the reason behind microscope problems, so extra care should always be taken in order to avoid this.

When you are moving your microscope around the lab, hold both the base and the metal support arm carefully. Never handle your microscope using the eye piece holder or the flat plate, as this can lead to misalignment. The flat plate is the part of the microscope where slides are positioned during an observation.

Use A Dust Cover

All BMS microscopes include dust covers as standard, and for good reason. You should always use the dust cover for this equipment, especially in storage and when moving the microscope around.

Whenever your equipment is not being used, put the dust cover or dust bag back on to protect it. Getting dust on or in a microscope can cause a lot of problems, and the easiest way to avoid this is a dust cover.

The eye tubes of your microscope should also be protected from dust, so if you remove them, make sure to cover them with caps and store properly.

Look After the Bulbs

Microscopes feature tiny bulbs which are used for the illuminator. Make sure you switch off the illuminator whenever it is not in use, in order to minimise damage. If the bulbs are left on for long periods, they will overheat and eventually blow, causing further damage to your equipment.

When you do turn off your illuminator, wait for it to completely cool before you put the microscope away. By allowing it to cool down, you can extend the lifespan of the bulb and avoid having to make replacements which can be costly.

Follow The Instructions

It might sound obvious, but the instructions and information provided in your microscope’s user manual are there for a reason. BMS microscopes will come with a manual as well as any specialist spanners which are required for adjustments.

Always follow the instructions carefully and only use the provided spanners to make microscope adjustments. Never use different tools than the ones provided, and never use force with your microscope. When you do make adjustments, avoid overtightening as this can damage the equipment.

Store Appropriately

The chances are your microscope is going to spend the majority of its time in storage. We have already discussed the importance of storing with a dust cover, but it is also vital you keep your equipment in a clean, dry space with plenty of ventilation.

Damp air near the microscope will cause damage over time, so make sure to keep equipment somewhere dry and away from anything that could leak.

Microscopes should also not be stored near to potentially corrosive chemicals which may give off fumes, as this can corrode metal parts and destroy the lenses.

The Differences Between Industrial and Commercial Scales

There are so many businesses and industries that rely on scales for their everyday applications. Scales are used for weighing products, materials, food items, and so much more, but not all scales are created equal.

These pieces of equipment come in various types and with different features and knowing which is right for your business or application is critical. When looking for scales for a laboratory or business, you will likely come across both industrial and commercial scales.

At SciChem, we work with some of the best scale manufacturers in the world, and we have the knowledge and expertise to help you understand which option is right for you.

One of our most popular scale suppliers is OHAUS, who have grown from a small repair business to a global leader in the weighing industry. Today, we are looking into the differences between industrial and commercial scales, and which OHAUS scales will be right for you.

What Are Industrial Scales?

Industrial scales are used to weigh products at an industrial level, and they are built to withstand high usage and harsh environments. This kind of equipment is durable, reliable, and very long lasting, and can often be adapted to suit changing requirements. Industrial scales are generally housed in factories or even laboratories, and can be used to measure large quantities quickly and precisely. This kind of weighing equipment does not have to meet the same legal requirements as commercial scales and are generally not NTEP certified. Despite this, they still provide very accurate data and are extremely precise for measuring all kinds of materials. They are larger than commercial scales, making them unsuitable for most retail environments where weighing is needed on a smaller level.

What Are Commercial Scales?

Commercial scales are generally used in shops, laboratories, and restaurants. They are small and compact, and often used in front of customers when weighing products, for example at a butcher’s counter in a supermarket. Unlike industrial scales, commercial scales must be regulated and meet the legal requirements set by the National Bureau of Standards. These standards relate to the accuracy, operation and label printing set up of the scales. Commercial weighing equipment is perfect for small shops, laboratory experiments, and small businesses. Failing to use scales which are certified and approved can leave your business liable to fines of more than £1000. It is a legal requirement that any scales used to weigh items which have a price based on the weight are trade approved.

What Are the Key Differences Between Industrial And Commercial Scales?

Now that we have covered what these two types of weighing equipment are, you should have an idea of which is suitable for you. If you are still unsure which type of scale is right for your application, then consider these three factors:

  • Size: One of the key differences between commercial and industrial scales is the size. This relates to both the size of the equipment itself, and the measures the scales can handle. Industrial scales are designed for large businesses and high usage, whereas commercial scales are better suited for small enterprises.
  • Certification: Some situations require scales which are certified and regulated. When this is the case, commercial scales are the only option as industrial scales are not subject to these rigorous checks and processes. This certainly doesn’t mean that industrial scales lack accuracy, just that they do not legally require the same certification as their commercial counterparts.
  • Packaging Products: If you are working in a situation where you need to weigh and package products in front of customers, or weigh materials for individual uses, then a commercial scale is best. Industrial scales are suited for situations where products can be weighed, packaged, and labelled without customer interaction.

OHAUS Scales From SciChem

OHAUS manufacture both commercial and industrial scales and are often some of the best weighing equipment on the market. They are a certified manufacturer of scales, and all of their products are trusted and approved for use across all industries. Our top selling OHAUS scales at SciChem are:

UV Spectrometers Explained

Measuring light absorbance across various ranges of the electromagnetic spectrum requires the right equipment, including UV Spectrometers. This kind of kit is commonly used in laboratories and for many everyday applications. UV spectrometers are just one type of spectrometer which is used by scientists and experts to measure wavelengths and radiation. There are many other types of spectrometers, such as a spectrophotometer or a mass spectrometer. Today, we are explaining everything you need to know about UV spectrometers.

What Is a Spectrometer?

A spectrometer is any piece of equipment that can be used to measure variations in physical characteristics on a given range, for example, the electromagnetic spectrum. UV spectrometers are the most commonly used type and are also referred to as optical spectrometers. They work to measure changes in the emission and absorption of light with wavelengths. Electromagnetic radiation, or light, can be absorbed by, reflected off, or transmitted through various objects, and UV spectrometers measure the changes that occur during these interactions.

How Does a Spectrometer Work?

An optical spectrometer works to measure the interactions or emissions between electromagnetic radiation and a sample. Also known as a light spectrometer, this kind of equipment looks at the electromagnetic radiation which falls into the optical regions of the spectrum. The electromagnetic spectrum includes ultraviolet, visible, and infrared light waves.

For a light spectrometer to gain the most information about the emission or interaction, it must measure as a function of wavelength. The common feature for UV spectrometers is a mechanism designed for a selection of wavelengths. Some simple spectrometers use optical filters in order to isolate a specific wavelength. For a more accurate selection of light wavelengths, high-end spectrometers have a dispersive element which separates light waves into the relevant wavelengths. All modern pieces of kit use a diffraction grating for this dispersive element. These use destructive and constructive interferences to separate polychromatic light.

Diffraction gratings are the key part of a monochromator. A monochromator works to select particular wavelengths from a polychromatic light source. With a monochromator, the diffraction grating rotates to adapt the wavelength which is aligned and passing through an exit slit. All spectrophotometers feature monochromators allowing users to select a specific wavelength.

Types Of UV Spectrometer

UV spectrometers comes in various types, and it is important to understand the differences:

Spectrophotometer

A spectrophotometer is also called a UV-Vis Spectrometer. This term actually refers to many devices which can measure light, but generally it is a term used for a spectrometer that measures light absorption by a sample. They use a white light source and a monochromator which works to select the wavelength of the light to reach the sample. This light is transmitted to the sample and monitored using a detector.

Spectrofluorometer

Another type of optical spectrometer is a spectrofluorometer. This equipment measures the fluorescence emissions from a specific sample. They are benchtop devices, similar to a spectrophotometer, but with advanced functionality. Just like a spectrophotometer, these instruments have a white light source and monochromator. The sample is then illuminated by the wavelength from the exit slit, causing it to fluoresce. This emission from the fluorescence then goes to another monochromator and then a photomultiplier tube.

Raman Spectrometer

These work to measure the Raman scattering of light. They work similarly to a spectrofluorometer, but with some key changes. Instead of a white light, they use a laser and there is no monochromator. This is because Raman spectrometer creates a light scatter from the sample instead of light being absorbed. The laser light scatters off the sample and is passed to a filter. The Raman scattered light then goes to a spectrograph and is then captured by a CCD detector.

What Are The Parts Of A Spectrometer?

UV spectrometers are made up of our various components, but the most critical parts of this equipment are:

  • The Light Source: All types of spectrometers must have a light source of some kind. Light sources come in many different types, but usually they are a deuterium arc lamp, tungsten halogen lamp, or Xenon arc lamp.
  • The Light Transfer: For most spectrometers, the light transfer system is the diffraction grating. Without this, you will not receive any readings on your spectrometer.
  • The Detectors: After the wavelengths have passed through the sample, they will go to the detectors. This is where the light intensity is detected and measured.
  • The Read Out System:Finally there is the read out system, which is essentially the computer within the spectrometer. It collects all the data from the detectors and converts it into measurements.

Choosing A Power Supply For Your Lab

One of the most critical features in any laboratory is the power supply. They are required for so many experiments and projects, and ensuring you have the right one for your applications and requirements is crucial. A faulty or incorrect type of power supply can be hazardous for yourself and your colleagues, while also impacting your work. There are a range of different power supplies available for labs, and they are necessary for supplying clean currents and stable voltages during your experiments.

At SciChem, we work closely with Lascells who are one of the top manufacturers of laboratory power supplies available today.

What Is A Laboratory Power Supply?

Power supplies are an essential piece of kit for any lab, as they are used to test electrical components and circuits. This kind of equipment is powered using voltage and they are used for many different projects and experiments at all levels. Sometimes referred to as benchtop power supplies, these are portable devices which can be used on a lab surface and moved around as required.

In some laboratories, mains adaptors are used as the main power supply, but this can be a problematic approach. Having a standalone power supply means you can clearly see both the current and voltage for your experiment, delivering a precise and reliable reading every time. Depending on the type of power supply you choose, you can also select specific voltages and currents for each project you are working on.

Types Of Power Supplies

Power supplies come in various different types and each work in a slightly different way. Simple devices are perfect for basic level experiments, and they feature two displays and two dials. You can set specific current and voltage limits for your project and choose from Constant Voltage (CV) mode or Constant Current (CC) mode. Generally speaking, there are two main types of power supplies for a lab; linear and switching.

A linear power supply often experiences high loss of energy and needs regular cooling with a fan. They are larger and heavier than switching supplies because they have a transformer fitted. Switching power supplies are much more efficient, and also smaller and more compact. This kind of equipment can emit a high-frequency noise and is not ideal for working with inductive loads like coils and motors.

Lascells Power Supplies

Lascells are passionate about ensuring science experiments and teaching of science is enjoyable for students and easy for educators. That’s why they focus on creating lab equipment, which is simple, effective, and reliable. They produce a couple of power supply products which are extremely popular in education and school laboratories around the world.

  • Lascells Revolution Variable Power SupplyThis compact power supply works up to 8A DC with the option for switched, variable or constant DC voltage. The maximum voltage limit is super simple to adjust, and this power supply also benefits from automatic overload protection and digital voltage readout. The lightweight case and compact design makes this power supply ideal for labs with limited space or for portable use.
  • Lascells Revolution Switched Power Supply: The Lascells switched power supply has a regulated DC output allowing the supply to remain constant no matter what is connected to the terminals. There is a maximum voltage limiter which is operated using an Allen key, allowing educators to set a maximum voltage for students to use. The compact design is easy to move around the lab as required and also takes up minimal storage space.

What To Consider When Choosing A Power Supply For Your Lab

Knowing the best power supply for your laboratory can be a confusing decision. To help you understand the right option for your requirements, we’re sharing the main things you should consider when comparing power supplies.

  • Power and Output: You can choose devices with a range of different power levels. Some can supply a current at any voltage while others support multiple ranges for a continuous transition. If you regularly need to test different devices simultaneously, then a power supply with multiple outlets is essential.
  • Safety Features: Look for power supplies with adequate safety features and DUT protection to cover you in case of failure.
  • Dimensions: The size and weight of the power supply is important to think about too. If you need to move the equipment around your lab often, or store them away, you should choose a supply which is compact and portable.
  • Specifications: There is a lot more to a power supply than just voltage, outputs and current. You should also take into consideration line regulation, readback currency, sense connections, interfaces, noise output, load regulation, and transient response.

Lab Balances – How To Choose The Right One For Your Industry

Lab balances and scales are used across a huge range of industries, not just in laboratories. Sectors including retail, industrial, education, and food all use balances and scales on a regular basis, and depend on them for their day to day applications. No matter the industry you are operating within, you need to have the right equipment in place in order to guarantee accurate results and efficient performance. Choosing the right balance or scale for your business is not always an easy decision, and it is vital you understand the ins and outs of these devices before making a decision.

Types Of Lab Balances

All balances work by measuring objects, and some offer extreme detail down to a granular level. Some industries, such as the food sector, will require ultimate detail and precision, while others, such as education might not require such detail. In order to choose the right lab balance for your industry, you need to be aware of the types available:

Compact Balances

This is a type of professional weighing balance which is compact in size. Due to their small nature, compact balances are portable, making them great for use in a range of industries, particularly when space is scarce. Most compact balances are digital these days, and come equipped with a stainless steel weighing pan. Stainless steel is usually the standard because it can withstand all substances and is very easy to clean after use. This is a great advantage in food or industrial settings.

Analytical Balances

Industries which require ultimate detail often choose analytical balances because of their ability to measure a mass right down to sub-milligram ranges. This piece of kit offers extremely accurate and precise results, perfect for situations where exactness is critical. Due to their sensitivity, analytical balances can be very susceptible to their environment. To deal with this, the weighing pan is isolated in an enclosed and temperature controlled environment. This protects products from particles, dust, air currents and more. Analytical balances are good for use in industrial or laboratory settings where there is a lot of other equipment nearby. This is because they offer great protection from electrical and mechanical interference.

Precision Balances

Any situation where complete precision is required can benefit from a precision balance. In addition to being incredibly accurate and precise, this kind of equipment offers a steady output even when conditions are not ideal. Unlike other kinds of balances, precision balances are much less likely to give a faulty reading during temperature fluctuations. These lab balances are the most common across a lot of industries because they offer accurate results and are easy to use.

Precision balances are a top choice among many industries including medical and pharmaceutical applications, where exact precision is critical. If you often need to weigh varied amounts in your business, then this is a great option as they can handle anything from a few kilograms to several hundred grams.

OHAUS Lab Balances For All Industries

At SciChem, we work with some of the best suppliers in the world. OHAUS are a trusted and certified manufacture of lab balances. They have products suitable for all industries, including:

  • Laboratory: In a lab environment, you often need to have a range of balances to hand for different experiments. OHAUS offer analytical balances such as the Pioneer Semi-Micro which delivers accuracy and repeatability for weighing applications in a lab.
  • Industrial: When it comes to industrial applications, OHAUS offer a range of industrial grade scales and lab balances. A popular balance for the industrial sector is the Compass portable balance which features an enlarged weighing platform, able to handle large samples.
