A Guide to the Different Types of Vacuum Chamber Materials Available

There are quite a few reasons why a material might be ideal for a vacuum chamber. First, the chamber needs to be fairly robust. Otherwise, it can compromise the results of your process or experiments.

It also needs to be able to maintain a vacuum state and keep external factors, elements, and forces out of your processes.

When it comes to choosing the right vacuum chamber material, you need one that can handle these rigorous demands while also fitting the specific purpose of your chamber. So how do you go about finding that ideal vacuum chamber material?

Here is a brief guide on the different types of materials commonly used in vacuum chambers.


Glass is the most commonly used material for vacuum chamber panels because it is durable and transparent. Most glass panels have a thickness of around 0.6 inches (15 millimeters). However, some advanced glass panels can be as thin as 0.3 inches (8 millimeters). This makes them more efficient when allowing light into the chamber so that plants can photosynthesize.


Plastics are another commonly used material for vacuum chamber panels because it is strong yet lightweight. The downside to using plastic is that it can become brittle if subjected to high levels of heat or pressure. This means that plastic vacuum chamber panels must be treated carefully to ensure their long-term durability.


Composites are also a popular choice for custom vacuum chamber panels because they offer strength and flexibility. Unlike plastic and glass, composite materials do not suffer from brittle tendencies when subjected to heat or pressure. Additionally, composite materials are more accessible to repair than either type of material if something goes wrong with them.

Non-Magnetic Flange Connection

A non-magnetic flange connection is an essential factor in ensuring vacuum integrity. Flanges must be made of materials that are not magnetic to avoid any interference with the physics of a vacuum. You can use a variety of materials for non-magnetic flanges.

Some examples of Non-Magnetic flange connection materials are:

Stainless Steel

Stainless steel is a common choice to its strength and resistance to corrosion. When selecting stainless steel for your flanges, choose a type that’s resistant to high temperatures and pressures associated with vacuum chambers.


Aluminum is another common choice for non-magnetic flange connection materials. Like stainless steel, aluminum is firm but lowly susceptible to corrosion. Additionally, aluminum is lightweight, which makes it easy to work with and transport around the lab.


Brass is another common choice for non-magnetic flange connection materials due to its resistance to corrosion and lightweight. You can find many parts of vacuum chambers for sale that are made of brass and are highly durable.

Choosing the Best Materials

Choose a material with a high vacuum rating. A high vacuum rating means the material can withstand higher pressure than other materials. Consider the cost and durability of the material. The price of a material will vary based on the type and grade, but generally, more expensive materials will be more durable.

Some materials are better suited for applications that require low humidity or extreme temperatures. While others may be better suited for applications that require high levels of airtightness or insulation.

Choose a Vacuum Chamber Material Wisely

When it comes to vacuum chamber materials, there are a variety of options available to you. This article provides you with an overview of the different types of vacuum chamber materials and their benefits. We hope that this information will help you make the best choice for your particular application.
