The PT-FC2 Fraction Collector can be attached to any PTA Dissolution Bath. Using either a Peristaltic-, Syringe- or Piston Pump the dissolution media is directly sampled into covered glass vials inside the sampling dish of the PT-FC2.
Depending on the system configuration sampling information such as interval timing and total number of sampling sequences is either programed at the keyboard of the connected dissolution bath or directly at the PT-FC2 panel (DFC 70).
Pinch Valves are used to switch the liquid flow. Previous to a sampling sequence the media is circulated within a closed loop betwenn the dissolution vessels and the PT-FC2. As soon as the concentration of the media is equilibrated the valves open for samling. At the end of a sampling sequence all tubes are automatically emptied. Adding an extra set of valves and a pump with more channels the PT-FC2 can also re-fill the sampled media.
