A rotary evaporator for continuous distillation
The Hei-Volume Distimatic Pro Benchtop G9BXL (photo) allows users to fully automate the filling and emptying of a benchtop rotary evaporator. Once programmed, the Hei-Volume Distimatic Pro module fills and drains the Hei-VAP rotary evaporator automatically and unattended. It detects when the media supplied has been processed and switches itself off automatically, including the peripheral devices. The automation eliminates the burden of handling of large rotary flasks, because the module can dispense viscous residues. Cleaning is also carried out by the automatic module. The parameters for the sensor- or time-controlled filling of the rotary flask can be entered via the removable 7-in. touchscreen control panel. The time for the coated collector vessel (approx. 330 mL) to be emptied by the compressor can also be programmed here. In addition, the automatic cleaning mode and manual operation can be started. The control box with the integrated compressor of the Hei-Volume Distimatic Pro, along with all of its components, can be mounted directly on a Hei-VAP benchtop rotary evaporator using the bracket supplied. All parts that come into contact with the media, including the supplied tubing, are made of chemical-resistant materials. — Heidolph North America, Wood Dale, Ill.
