Pharma Test Dissolution Media Addition System
The L-MDS-600 media addition system is an upgrade to a Pharma Test PTWS 820D tablet dissolution testing instrument. It is used to automatically add 250ml of medium to the dissolution vessels inside the PTWS 820D within a maximum of 20 seconds at a programmable point in time.
The system has a separate water bath with dedicated temperature control system. The concentrated buffer solution is stored in an individual vessel for each vessel of the PTWS 820D Dissolution testing instrument. The temperature of the buffer solution is critical as 250ml of medium is added to each dissolution vessel and the temperature in the vessel should stay within the USP requirements during this process. The addition is done by gravity using switchable valves and through a tubing connection to the vessels inside the PTWS 820D dissolution bath.
