Whether being used in laboratories, for research or development processes, it is essential that many parts and materials are free of contamination. Element’s vacuum bake-out testing helps successfully complete removal of volatile compounds before they contaminate systems or components. 

During a vacuum bake-out process the test items are exposed to high temperature in vacuum to remove gasses, water vapor and other contaminants. Once this is achieved, vacuum baked components can be used in ultra-high vacuum (UHV) or ultra-high purity systems. 

Vacuum bake-out testing for space 

Element’s vacuum bake-out testing offers burn-in and discharge testing solutions to simulate in-space atmosphere and temperature conditions to verify flight hardware operation prior to its use in space. 

Our vacuum chambers are designed to specifically to meet the stringent demands of space simulation. This includes extreme environmental conditions such as alternate cycles of extreme heat and cold, pressure extremes, solar radiation levels, and the airless conditions of space.

At Element, we are committed to developing the best possible solution to your projects with comprehensive data collection tools, helping you ensure your equipment is ready for the extremes of outer space.

Vacuum Bake-out Methods

Our specialists use a wide range of vacuum bake-out methods. From Vacuum drying to corona discharge testing, we identify the best solution to examine the reliability of your products, validate their design and quality as well as provide evidence of regulatory testing requirements. 

High Vacuum system bake-out

Although there is great demand for low-level vacuum bake-out testing, we can also provide high vacuum if required depending on the material loaded into the chamber. High vacuum levels are in the vacuum range characterized by pressures range 10-3 to 10-6 Pa. 

Ultra High Vacuum (UHV) bake-out

UHV bake-out requires baking the chamber to remove traces gases at very low pressures, below 10 - 7 Pa (10-8 Torr). 

Vacuum drying

Vacuum drying is the most effective way to safely remove moisture from delicate and heat-sensitive products. Element’s Engaged Experts are able to develop test procedures for your products to maximize consistent drying in the shortest time. 

Burn-in testing  

To avoid system failures in electronic components, burn-in testing at elevated temperatures and voltage exercises components to determine the “first to fail” or assess high failure rates of system components.


From satellites and space-based equipment to medical systems and equipment, volatile organic compounds can impact a wide range of application areas in electronics. Element’s specialists provide outgassing testing to high-quality materials in well-controlled laboratory environments. 

Residual Gas Analyser (RGA) 

RGA is mass spectrometer to identify and measure the type of particles and solvents which remain following a bake-out or outgassing procedure. It enables detection of contaminants at low levels before a process is initiated, to better determine when a part or component is sufficiently decontaminated. 

Cleaning & sterilization 

Cleaning of space hardware that involves high temperature and high vacuum environments to removing contaminates, controlling stress corrosion and contamination of material used in space applications.

Quartz Crystal Monitor (QCM) system 

Element’s Experts use Quartz Crystal monitors to monitor the rate of outgassing.  

Epoxy resin curing

Element investigates fracture toughness and fatigue crack growth behavior of epoxy resins in aerospace applications. Vacuum ovens are used for degassing epoxy resins in order to remove voids before curing.

Corona discharge/arcing 

High-powered components can exhibit arcing/corona discharge at high altitude. If arcing and corona discharge are believed to be potential problems we conduct a test that evaluates the effect of outgassing, and vacuum bake out is one of the outgassing methods to be used.
