Automatic Media Preparation System

Dispensing Arm during media filling

Our recommendation for busy dissolution laboratories which demand both speed and accuracy, we introduce the perfect media preparation system which fills your vessels simultaneously.

The equipment delivers pre-heated, filtered, de-aerated, volumetrically dispensed media to six or seven dissolution vessels in less than five minutes. Built on a unique ergonomic cart, the Media Preparation System offers the maximum portability for easy servicing of many dissolution test stations of almost all brands.


Interchangeable pre-heat tanks accommodate 10-40 L media and buffers with precision temperature control.

Delivery volume is adjustable 250 to 1000 ml in 50 ml increments (± 1% accuracy). Media de-aeration is below 95% saturation when delivered to dissolution flasks (de-aeration is achieved using thin film treatment in a vacuum). The convenient dispense arm fills 3+3, 4+2 or 4+3 flasks layouts.
