ERWEKA DT 720
6, 7 and 8 stirrer type
ERWEKA DT 720 has been designed with the
user in mind: instead of an extensive operation
menu structure and multi-functional keys the DT
720 comes with individual displays for each
test-run parameter (time, rpm, temperature).
UP/DOWN buttons for fast and easy test-run
parameter setting are placed. For better obser-
vation of the sample dissolving process the
one-piece moulded water bath (with standard
water outlet cock) is illuminated (optional).
The manual lifter column, with hydraulic support
for effortless operation, allows raising and low-
ering of the drive head in just a few seconds.
Tablets/Pellets etc. are inserted through the
sampling openings in the drive head via the
standard tablet delivery system. Samples for
analysis are withdrawn through special, mem-
brane sealed sampling openings inside the
drive head. Evaporation less than 0.3% in Low
Head mode and less than 0.7% in High Head
mode (24h/37.0°C).
The extensive use of carbon fibre allowed to
eliminate metal and therefore reduces the risk
of corrosion to a minimum.
The actual test-run parameters can be docu-
mented via an USB printer (optional).
