Inert Atmosphere Processing

Why Buy the Ossila Glove Box

It is important for you to understand the benefits and limitations of different inert atmosphere systems before making the investment. If you are looking for a robust, easy-to-use system, the Ossila Glove Box is the perfect choice for you.

Choosing the right glove box for your needs is important. The system should be suitable for your samples, experimental requirements, laboratory environment, and budget.

There are several important components to consider when designing a glove box. Importantly, they should be designed to reduce leakage as much as possible.

Working safely within a glove box requires the care and co-operation of everyone who uses it. For this reason, we recommend outlining a standard operating procedure for your laboratory.

The Ossila Glove Box is designed to be easy to install and maintain, and is suitable for most laboratories. Its small footprint and quick set up also means that it is relatively portable and can be conveniently transferred between labs as required.

Glove box gloves must be flexible and relatively thin to allow movement within the main chamber. This will be the most vulnerable exposure point to air and moisture as small holes can easily occur here.

Materials processed within a glove box can directly impact the quality of the atmosphere and the ability of the system to maintain an inert atmosphere.

Maintenance and Troubleshooting: Glove Boxes

There are a number of steps that you as the glove box user can take to ensure that the inert atmosphere remains intact.

It is also important to be able to quickly identify, troubleshoot, and fix problems as they occur.

Feedthrough points allow you to pass lines and cables from the external to the internal environment. There are several different ways to create the required feedthroughs in your glove box.

Antechambers are small, isolated compartments. They can be exposed to atmosphere more often than the main chamber as it will take them much less time to achieve inert conditions. You will use these to move small items in and out of your glove box.

If you suspect a leak, the first thing you should do is perform a leak test. Leak tests raise the glove box to an extreme positive or negative pressure and then measure the rate of change of pressure over a period of time.

Our glove boxes run at an overpressure, so if the leak is small, the glove box may still be able to maintain the integrity of the internal atmosphere. However, during this time, the glove box will use a much larger amount of inert gas than normal as the overpressure in the glove box will result in a flow of gas from the inside of the system to the outside.

How to Make a Perovskites Solar Cells in a Glove Box

This video is a guide on how to make perovskite films when processed inside a nitrogen filled glove box. The resultant devices achieve efficiencies greater than 19% PCE.

A glove box is suitable for a variety of applications across the world of science and research. From organic electronics to additve manufacturing, the inert atmosphere provided by a glove box is critical in many settings.

The highest performing perovskite solar cells were all made in glove boxes. This case study to investigate how inert does an environment need to be for a given process and is the Ossila Glove Box effective.

Film and device encapsulation involves applying thin protective layers onto the surface of your electronic devices. Encapsulating your devices inside a glove box environment limits their exposure to contaminants

Inert gases are gases which are chemically inactive, so will not undergo chemical reactions with many materials. Inert gases are used for many purposes in a wide range of industries - for example in welding, chemical processing, and as filler gases in light sources.

Defining Moisture Content in a Glove Box

There are multiple ways of defining how much moisture is present in the air. With clear definitions, guidance on converting values, and a simple conversion table, you will easily be able to work with any of the available definitions to control the moisture content in your glove box environment.

Argon and nitrogen are both unreactive gases which can be used to create an inert environment within a glove box. Both gases will efficiently displace air within a confined space, are easy to store and will not react with most materials. Therefore, both N2 and Ar can create a glove box environment with very low moisture and oxygen levels.

Glove boxes can be maintained at positive pressure or negative pressure. Both create atmospheres separate from ambient, keeping a barrier between your materials and the external lab environment.

Some materials can degrade or decompose over time due to exposure to oxygen or moisture. This can be accelerated by exposure to light or increased temperatures. Other materials can absorb moisture from the air causing them to aggregate.

Air free techniques are essential for the handling and storage of materials that are unstable when exposed to air. Compounds are defined as unstable if they react with an element in air, often moisture or oxygen.
