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.

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.

Lab Equipment: A Selection Guide To Right Laboratory Glove Box

A laboratory glove box is a device that makes it possible to work in the laboratory without isolating oneself from the world. The box is used to control spillage and contamination from substances being worked with, giving the operator access to an open environment without risking contamination of either themselves or the lab.

If you're looking for a new or refurbished glovebox, this guide will help you find one at an affordable price for your lab. Here are a few common types of glove boxes that are currently trending in the market:

Controlled Atmosphere Glove Box

A Controlled Atmosphere glove box is usually used in the research labs for doing experiments. These boxes are built, so that standard atmospheric air (21%) or Nitrogen gas is maintained inside the chamber to ensure safe working conditions. This method is used when one of the materials handled inside the glove box is highly flammable or dangerous for lab workers.

Positive Pressure Glove Box

A Positive Pressure Glove Box has an intake of clean air and an exhaust system that prevents any contamination from within the atmosphere to the outside atmosphere. In other words, it has positive pressure as opposed to exothermic/endothermic work, which involves negative pressure. Positive pressure means that the glove box is always filled with clean air and thus doesn't require frequent input of new clean air.

Negative Pressure Glove Box

A Negative pressure glove box has an exhaust system that constantly removes contaminated air from inside the chamber and replaces it with new incoming clean air. This method is generally used in exothermic/endothermic work, such as when one of the substances being worked on is highly flammable or reactive to the outside atmosphere.

Lab Bench Glove Box

A lab bench glove box is a device designed for experiments with liquids and solids that are not climatically sensitive or are not temperature or humidity sensitive. This type of glove box is mostly used in academic and research laboratories.

It is important to find a reliable company that provides glove boxes known for their quality. Also, consider if your budget allows you to purchase a new glove box or one that has already been refurbished. It may be cost-effective in the long run if you opt for a refurbished version, but make sure it will meet all of your needs.
