Best Gravity Convection Oven | What Is A Vacuum Oven Used For?

If you are thinking about what is a vacuum oven used for? and what are the best vacuum ovens available in the market? You are finally at the right place where you will get to know everything about vacuum and gravity convection ovens.

What is the vacuum oven used for? & How do vacuum oven work?

Vacuum ovens are extremely flexible and adaptable pieces of equipment with uses in lab research, engineering, and industry. Vacuum ovens are used mainly for drying, preheating, quenching, sterilizing, aging, annealing, baking etc. In a vacuum oven, the objects are heated in a vessel that is air-tight. The atmosphere can be altered to some extent as well. The benefits of using a vacuum oven for drying is that

  • prevent reactions, such as oxidation or decarburization
  • Helps in removing contaminants such as oxide films and residual traces of lubricants
  • It uses the process of degassing to remove contaminating substances from metals

Heating sources for vacuum ovens include arc, electric, and induction. The items are heated using magnetic fields with a range of temperature which is within or above the transformation and then is followed by immediate quenching. Vacuum ovens have some great features to such as recovery of solvent or residual gases to prevent over-drying.

What is a Gravity convection oven? Where is it used?

A clear gravity convection oven definition is that they use gravity to circulate air in the chamber which disturbs the thermal process such as of different powders of material which are not too heavy. They are specially made to meet the needs of the school, laborites in industries and in research centers which require low-temperature applications. They are used for different purposes such as baking, sterilizing, evaporating and many other in lab research. The Gravity connection oven highest temperature point is 235°C (455°F).

The gravity convection oven and vacuum ovens are being used not only in laborites or industries but it is used in hospitals as well.

Following are the most effective vacuum ovens and gravity convection oven available in the market which are safe works great and are worth their price.
