Our Vacuum Oven Created specifically for low temperature vacuum degassing of essential oil extracts ,for ultimate temperature control this includes extra insulation to prevent unwanted heat loss.

Why Use Cema Instrument Vacuum Oven?

When degassing solvent, even, low temperatures are desired to prevent decomposition of the extracts volatile terpenes. Terpenes are the compounds that give an extract most of its aroma and other unique properties.

It does not take much to evaporate terpenes, which is one of the reasons why you can smell them so easily.

If you degas at too high of a temperature these compounds will boil off, leaving your extract with less aroma and flavor.

Cema Instrument Vacuum Oven gives you the control needed for maintaining those delicate ambient temperatures.

Cema Instrument Vacuum oven also prevents oxidation of the terpenes during the purging process by eliminating the oxygen and lowering the boiling point of your solvent.

Doing so ensures that you have a repeatable process that always produces clean, solvent free extract.

What is Nitrogen Inlet Port?

Our Vacuum oven also includes our specifically designed  3/8" for adding a nitrogen gas system to the Cema Instrument oven.
The advantage of using nitrogen gas is that it will speed up the degassing process by ensuring the air you let in is clean and 100% dry.
Using a dry gas also allows you to keep the extract pristine and clean, by preventing degradation due to over boiling.

Nitrogen gas purging can reduce purging times from 60-90 hours, down to just 24 hours!

What is Mica Heating Pads System?

Compared to the industry standard of heating tubes,Our 1.9 Vacuum Oven adopt Japnese Vacuum Oven Heating Core design, utilizes three shelves that further help to distribute heat evenly and efficiently with our new racking system, increasing contact with heating elements of the system. The precision of our upgraded temperature controllers, any temperature variances will be eliminated, helping you achieve a clean, consistent more desirable end product.

What is Direct Heated System?

Each shelf has its own heating element embedded within giving you the closest contact and even distribution from the heat source to your extract.
This is extremely important since heat cannot travel through a vacuum (nothing) efficiently. Heat is the movement of molecules so in a vacuum there is no air or nothing to transfer the heat. Unlike a convection oven heat has to conduct through the shelf itself and into the extract directly.Direct Heated System Technology allows for maximum Slab Space and precision temperature control. Why should anything else be between your heat source and your extract! Individual PID controller enables users to target shelf temperatures accurately without concern for overshooting.
