The Evaporator-VIS

The illustration shows the standard version of the device for use with 3 heating blocks for 72standard test tubes Ø 16 mm.

The heating blocks are equipped with longitudinal slots so that the falling liquid level in the front blockcan be observed. A fluorescent lamp provides better lighting conditions. Under these conditions, it ispossible to concentrate the samples to a residual volume.

The nitrogen supply for the rear heating blocks can be opened with a time delay. Most of the solventhas already evaporated, as it is not necessary to monitor the liquid level during this phase.After removing the front block, the blocks behind it are pulled forward to stop evaporation in the finalphase.

Thanks to this time-saving procedure, the Köhler VLM Evaporator VIS enables a high samplethroughput.We supply heating blocks for test tubes, Eppendorf reaction vessels, chromatography vials, roundbottom and pointed flasks.The gas dosing unit is divided into three chambers, each of which is supplied with nitrogen separately.

The flow rate for each of the up to 72 samples is set individually using the valve screws. Unused outletsremain closed. Instead of stainless steel capillaries, glass Pasteur pipettes can be used after attachingthe adapter plate.

The thermostat is equipped with a JUMO microprocessor PID controller and ensures precisetemperature control of the samples and compensation for evaporation cooling.
