How to Achieve Precision Scale And Balance

In academic and industrial research and quality control labs, an analytical balance is precision equipment that needs considerably more care and attention than the usual industrial scales and balances. There are many analytical balances on the market, and each one has its own unique set of specifications. So lab workers should be informed of how and when to use these instruments to ensure that equipment accuracy is maintained and prolong the lifespan of these instruments to the greatest extent feasible. Here are a few basic guidelines to keep in mind. There are times when the balancing operations manual is the only source of information.

Construction of an Analytical Equilibrium

The precision scale should be packaged on a flat, level surface that is free of severe heat, temperature variations, direct sunlight, draughts, high humidity, mist, dust and vibration. Accuracy may be affected by any or all of these variables. After that, open the balance and follow the steps provided to set it up.

A Balance Analyzer Is Required

Kern precision scales and analytical balances employ moulded plastic housings to prevent draughts from interfering with the accuracy of their measurements. After the samples are placed on the weighing plate, and the housing door is closed, you should wait approximately three seconds before taking a reading. Avoid tampering with the balance during weighing processes if at all feasible.

Checking Your Results Using an Analytical Balance

Before using a Precision Scale and Balance, it must be calibrated. The equipment may need to be recalibrated if it has been moved to a new location or subjected to significant changes in the temperature, humidity, or other environmental factors.

Keep everything in its proper place!

A thoroughly cleansed analytical balance is required for reliable results. It should be disconnected from the power supply as soon as feasible, and any spilled samples should be cleaned up immediately. Use a soft brush or a vacuum to remove any leftover residue. Wet towels soaked in mild soap should be used to clean surfaces. Precautions must be made to prevent liquid from entering the device. Completely dry the item with a fresh towel.

How Does a Nitrogen Desiccator Work in Lab?

As nitrogen is inert primarily (it does not react with stored items nor does it transmit moisture), it is the most often used medium for contaminant-free storage. It can be separated and purified at a cheap cost.

What Is essential?

There must be a proper flow of nitrogen in desiccator cabinets so that all moisture and contamination-containing air is removed. Because nitrogen has lower specific gravity than air, the heavier air is purged from the bottom region of the desiccator by introducing nitrogen into the top area.

Desiccators Not Maintained?

If a desiccator is not adequately bled and maintained, it might result in catastrophic failure. Moisture may permeate a desiccator's molecular structure, needing baking or vacuum processing to preserve the items being stored.

A Desiccator May Be Put To Use In Two Ways: As A Drying Device And As A Storage Device

There are two ways to utilize this airtight container. A desiccator's interior may be dehumidified first to prevent moisture particles from damaging moisture-sensitive goods like electronics and chemical samples that may react when exposed to moisture. Maintaining a stable humidity level while protecting biological and carbon dating materials from contamination is the second technique.

Desiccators for Dry Boxes

A wide range of manufacturing processes, from semiconductors to biopharmaceuticals to medical devices, are used in labs to meet these and other sectors' demands. Our desiccators are designed to reduce the relative humidity (RH) in a cabinet to 0% so that moisture cannot affect the sample that is being stored inside.

Relative humidity of 0 percent may be achieved by introducing Nitrogen (N2) into the chamber. When oxidation is not necessary, nitrogen is utilized as a replacement for air. It is feasible to separate and purify nitrogen cheaply since it does not react with stored chemicals.

Last Words

A desiccator may employ silica gel cartridges as alternative desiccants in the form of silica gel cartridges. You can recall finding little packets of beads hidden within a new pair of shoes in the past. As opposed to silica gel cartridges, silica gel packets have a more manageable size. Use these cartridges to keep samples dry since they remove moisture from the chamber.

Difference between Medical and Lab Refrigerators

Many people believe that lab freezers are no different from medical refrigerators, which is a common misconception. Some people believe that laboratory freezers are just more oversized copies of their own. Both have their advantages and disadvantages, but a few stand out. To ensure the long-term preservation of laboratory samples and materials, the freezers in the lab are equipped with temperature-controlled storage. Keeping a steady temperature in these freezers is essential to maintaining a stable environment. You'll discover more about the distinctions between Medical refrigerators and those in a laboratory by reading the below points.

Types of Lab Fridge

There are primarily two types of laboratory freezers. The chest freezer is the first, and the upright freezer is the second. These two vary significantly in terms of how much floor area they need. The compact footprint of upright refrigerators does not compromise storage capacity. Medical refrigerators, on the other hand, come in a single model.

Keeping the Temperature in Check

Maintaining a controlled atmosphere is critical to the proper operation of a lab freezer. The lab fridges' room must also be appropriately controlled and maintained. The compressor is more susceptible to damage at high temperatures because of the increased pressure pressing on it. Adequate air circulation is essential to the proper operation of the freezers. It's not necessary with a medical freezer, though. High-temperature freezers may be used.

Efforts to Dissipate

There will be greater heat output if you have many lab fridges in the same room. Increasing the temperature in the room can raise the pressure on your compressor, causing it to work more. The lab fridges are not defrosted automatically since it might harm the samples inside. On the other hand, medical refrigerators have auto-defrost capabilities and do not suffer from heat emissions.

A Built-In Security System

Security considerations are taken into consideration while designing lab fridges. Many laboratory refrigerators include built-in alarm systems that sound when the temperature drops too low or rises too high. Various security solutions are available, including password-protected locks and safety seals. Medical freezers, on the other hand, do not have these features.

Conclusion

This is how a laboratory refrigerator differs from a home refrigerator. The design systems of these two refrigerators reflect the fact that they were built for various reasons.

10 Tips for Maintaining Laboratory Equipment

Equipment maintenance should be your first priority, regardless of whether you're trying to keep within your budget or guarantee that your tests go off without a hitch. Below is the checklist for routine maintenance of laboratory equipment.

Every day, do the cleaning.

It's good to have a simple lab housekeeping checklist to remind lab personnel of daily responsibilities, including removing and cleaning counters, sweeping floors, and sanitizing the most frequent lab touchpoints.

Refrigerator and freezer inventory is essential, and it should contain critical information about the contents, including the origin and expiry dates.

Clean your glass correctly by using the recommended cleaning methods.

Routine glassware cleaning may be handled using a lab washer-disinfector with hot-air drying capability.

Glass recycling

Keep a garbage can for broken glass and other items with sharp edges in a place where everyone on the team can quickly access it.

Take a closer look at the emergency gear.

Make sure your lab's sprinkler and fire safety systems are inspected regularly.

Repairs

Occasionally, Laboratory Equipment may fail and cease operating. Instead of tossing out broken equipment, check whether it can be fixed or if it can be repaired with new components.

Conclusion

The equipment in your lab will work more smoothly if you follow these accessible cleaning practices. Daily, wipe down any exposed surfaces, and once a week, schedule a comprehensive clean.

The Process of Cleaning a Table Top Laminar Flow Hood

If you run a laboratory, you must be aware of the importance of air filtration and cleanliness in the environment. The same case is applied in the case of tabletop laminar flow hood. However, cleaning such laminar flow hoods is not an easy nut to crack. Instead, this is a delicate process that requires attention and some effort. Here’s a step by step guide for cleaning a Table Top Laminar Flow Hood effectively.

Start With Cleaning the Wall of the Hood

Since the wall is the first surface that you notice when you look into the hood, the wall must be clean and germ-free. First, clean the walls with a microfiber cloth dipped in alcohol. If there are some stains or grease, use a strong cleaner to remove them.

To Ensure That Your Hood Is Clean

To ensure that your Table Top Laminar Flow Hood is free from bacteria and germs, use a dry cotton towel to wipe down every surface inside of your hood. Use a small amount of solvent cleaner to wipe down quartz glass surfaces that must have been contaminated during experiments.

Clean the Back Wall from Top to Bottom

The back of the hood can be easy to forget with it being hidden from sight. However, it is important to clean this area because you can get bacteria from this part of the hood. To ensure that any traces of bacteria on the back wall are gone, use a microfiber cloth dipped in alcohol and wiped down every surface from top to bottom.

Cleaning the Inside Walls

The inside walls are generally easier to clean than other surfaces on the laminar flow hood since they are not so visible and have been covered by other surfaces in between your experiments. However, it is still important to clean the inside walls to ensure no bacteria or germs are left behind and that your experiments are free from any type of contamination.

Using a proper cleaning method and keeping a regular maintenance schedule will ensure your laminar flow cabinet provides safe and accurate results. Dry cotton cloths dipped in alcohol can be used to wipe down your quartz glass surfaces regularly and ensure that they remain clean.
