DT 720

figure 2

The ERWEKA DT 720 series has been designed in accordance with USP/EP/JP requirements for testing tablets and other dosage forms. It combines state-of-the-art with excellent and user-friendly design. The high-head and low-head operating modes offer highest flexibility. The tester can be used as a stand-alone device as well as a dissolution system equipped with an automated sampling station, operated via the ERWEKA Disso.NET software.

 The manual lifter column with gas-strut support allows effortless and rapid lifting and lowering of the drive head in just a few seconds. Tablets, pellets and other dosage forms are inserted in the drive head via the manual tablet drop magazine. Samples are withdrawn for analysis through special, membrane sealed sampling openings inside the drive head. The evaporation is less than one percent during 24 hours (37° C, 50 rpm, 1000 ml).

The extensive use of carbon fibre allowed us to eliminate metal usage and therefore to reduce the risk of corrosion to a minimum. Test run parameters can be documented via the USB-A printer interface (optional).

Two Shaft Length

The DT 72x can be fitted with high-head or low-head operating mode and appropriate stirring devices (i. e. paddles made of stainless steel or fluoropolymer, basket holders and rotating cylinders). Due to the special design, height adjustment is not required.

Additionally, further stirring methods can be employed individually. The DT 720 series therefore is the perfect choice when staggered test starts are required.
