Rotary Vacuum Evaporator
Specifically configured for culinary applications
The PolyScience culinary evaporator package gives you unlimited possibilities in evaporation, distillation and separation, concentration of flavors, and purification of liquids.
The main components of this culinary system are a Heidolph rotary evaporator, PolyScience LM6 Mini-Chiller, and a vacuum aspirator pump.
Essentially, the system allows vaporizing liquids at room temperature level. This happens by changing the atmospheric pressure inside the system by the use of a vacuum pump. As a result most of the volatile aromas are preserved.
The heated water bath and rotating flask of the Heidolph VAP Advantage provides increased surface area that releases vapor into the distillation glassware. Once the vapor reaches the condensing part of the glassware, the PolyScience LM6 Mini-chiller cools the condenser coil up to -20°C to allow for a quick condensation.
1 Gallon - 100% pure lab-grade Propylene Glycol anti-freeze for use with the LM6 mini-chiller. Dilute with 50% water. FDA rated as "food-grade."
PLEASE NOTE: While Propylene Glycol is considered food grade this is not meant to suggest that it is safe for consumption. Always check your chiller and rotary evaporator for leaks. In case of consumption please contact your local Poison Control Center immediately for instructions.
While most chefs are familiar with regular distillation process, this technology adds another dimension: it works under reduced pressure, which lowers the boiling point to as low as 95°F/35°C. By remaining at such low temperatures, valuable flavor compounds are preserved and will add to complexity of the result.
At Alinea Restaurant in Chicago the rotary evaporator is used to extract herb aromas like basil. Another innovative application by Alinea is to distill the pure chili's essence. During that process the chemical capsaicin, responsible for the heat, is left behind. A unique flavor experience is guaranteed.
The culinary distillation package includes:
- Hi-VAP Advantage HL rotary evaporator
- PolyScience LM6 Mini-Chiller with integrated fluid pump
- Vacuum Aspirator Pump
- Tubing and fittings
