The MediPrep 820 series offers quick and easy preparation of up to 8 liters of dissolution media in less than 15 minutes. The MediPrep 1622 takes just 25 minutes to prepare dissolution media - three times faster than manual preparation according to USP. The media for dissolution tests can be precisely mixed, heated, degassed and gravimetrically filled into vessels in a single pass. Foaming media such as SDS (Sodium Dodecyl Sulfate) can also be used.
Filling can be carried out via the integrated dosing connection or directly into the containers using the optional remote filling hand.
Additionally, the MediPrep 1622 has two inlets for premixed media and an outlet for waste water. An automatic cleaning process is integrated to prevent cross-contamination.
With a filling accuracy of 1 % for volumes from 500 ml to 2000 ml, there are instances where measurements for 250 ml do not meet specifications. To ensure a properly filled vessel with 250 ml, we recommend adding at least one additional vessel to the MediPrep 1622 filling method. If the filling is not within the specified accuracy, the excess volume should be discarded.
