The DK 20 model is able to house 20 test tubes of 300 ml with the diameter of 42 mm.
The digester DK 20 is made up of a aluminum heating block that offers excellent thermal homogeneity, with a maximum working temperature of 450°C.
The block’s temperature is controlled by dedicated microprocessor electronics. The temperature probe does not require calibration since the electronic automatic calibrates the device every time is turned on. All of this makes it possible to obtain excellent test precision and repeatability.
DK 20 is provided with a wide range of options (temperature selections, programmable permanence time, “continuous” working mode availability) and with a visualization display which allows to set the desired values and to monitor the digestion progress.
In compliance with GLP (Good Laboratory Practices), the data referring to the tests being run can be sent to a printer or PC for storage.
DK 20 has a special tube and fume hood support system able to help cool the samples, make their treatment safer and save space.
In order to neutralize the fumes produced during the digestion, DK20 should be combined with a proper aspiration pump and fumes neutralization system. Velp suggests the use of the DK20 in combination with the JP pump and the SMS scrubber unit.

The “Operating Accessories” indicated are necessary for the correct functioning of the instrument.
