Brand: Erweka | Category: Scientific & Laboratory Equipment
Erweka state that the RoboDis II+ is the only simultaneously operating, fully automatic dissolution test system currently on the market, with every stage of the dissolution process computer controlled and carried out without user intervention. Disso.NET is the key element, controlling all system functions including precise movement of the robot arm, control of the analysers, data processing and full documentation. In standard configuration it tests up to 10 batches to USP method 1 (basket) or 2 (paddle), and the parallel sampling approach gives very short cycle times for detailed drug release profiles. Integrated System Suitability Tests and video monitoring support reliability, and a 10 batch system needs no more than 2 x 1 m of floor space.

Erweka position the ZT 120 Light series as the entry level disintegration tester, with one or two motor driven USP / EP / JP compliant test stations. The compact unit carries an integrated flow through heater and a moulded one piece PET water bath with a cover, which Erweka note will not leak or break and is easy to clean. Operation runs from a membrane keypad, where run time and water bath temperature are entered with symbol keys and actual values appear on large bright LED displays. The run time counter starts automatically as soon as the basket rack assembly is lowered into the test media.
Erweka's HPLC on/offline system is the semi automated route to 100 % USP / EP / JP compliant dissolution testing with HPLC online analysis. Up to 5 of the 8 dissolution steps can be automated by pairing a DT 950 or DT 9510 series tester with CTC sampling and online HPLC chromatography, the whole set controlled by Disso.NET. For filtration at 0.45 µm the automatic filter changer AFC 825 works alongside the maintenance free PVP pump, with other filter sizes available on request. After the dissolution test and double filtration with the PVP 820 pump and the AFC 825, medium is transferred to the HPLC sampler, filled into a PEEK transfer block and distributed into vials, where samples can be diluted for immediate analysis or cooled and shielded from UV radiation for later analysis.
On the ZT 320 series the one to four test stations are driven individually, and each station has its own keypad. Once the required run time is programmed, the basket rack assembly with its loaded samples lowers automatically into the media, and on completion of the preset time or when the stop button is pressed the rack is raised out of the media to prevent further disintegration, which is optional. Temperature shown on the LED display is measured by the standard external sensor sitting either in the water bath or in the test media. Recorded test run parameters can be hard copied through the USB printer interface and the actual disintegration time added manually afterwards.
