Baths

The Thermotita is a perfect water bath to keep regulate the temperature of cannabis crude, oils, tinctures and distillates.

Baths

Cart Fillers

The Magma cart fillers feature a patented heating rod design for easier and more accurate dispensing. In as little as 3 minutes, heat up your product to a set temperature and maintain a constant temperature effectively.

Cart Fillers

Chillers

The Aquilon recirculating chiller features PID temperature controllers to provide accurate and reliable temperature control. Designed for continuous and reliable operation. Choose from cooling capacities of 600W , 1300W and 1600 W to shorten process times and boost solvent recovery rates.

Chillers

Cold Trap

The Aquilon cold trap is a device that condenses vapor into a liquid or solid (ice). Cold traps also act as cryo vacuum pumps thus dramatically shortening process times.

Cold Trap

Vacuum Ovens

The Hephaestus vacuum oven is designed for drying and vacuum purging materials which are thermosensitive, oxidative or easily decomposable. This includes cannabis flower just as much as shatter or isolates. To further reduce oxidation e.g. to protect THCa you can purge or vent the oven with inert gas to displace any oxygen present.

Decarb Ovens

The Hephaestus convection oven is designed for drying or melting materials which are thermosensitive, oxidative or easily decomposable.

Convection Ovens

Rotary Evaporators

Our Rotary Evaporators are highly efficient and easy to use. The bath temperature of up to 180°C covers all common solvents and even allows for in-evaporator decarboxylation if required. All Holland Green Science Rotary Evaporators are made to safely utilize Distilled Water or Oil in the bath! This allows you to process safely at higher temperatures, and also allows you to decarb using our RotoVap.
