Whenever automated sampling is required the PT-FC2 fraction collector together with a pump offers an ideal choice. The control of the PT-FC2 fraction collector with respect to sampling times, dosage volumes, refilling and pump drive is done via the keyboard of the PT-DT70 dissolution bath. Enter sampling times and sampling volume at the keyboard of the PT-FC2 and connect the system components together for a semi automated operation.
Correctly positioned sampling tubes, equal sampling times and standardized solvent transport offer a high standard of reproducability and reliability for dissolution tests.
Also the economical aspect will show that automated sampling offers advantages as the operator does only need to fill the flasks and introduce the samples, thereafter the system operates automatically. Using a PT-FC2 fraction collector means that the way of analysis is open for spectrometer or LC. The filled vials within the vial dish are manually moved to the analiser and either manually injected or transferred to an autoinjection system.
A typical semi automated DFC 70 dissolution test system is composed of the following instruments:
PT-DT70 Dissolution Bath, PTFE tubing installation, Peristaltic-, Syringe- or Piston Pump, and a PT-FC2 Fraction Collector. Refilling can be automated, too using a 16 channel pump and a refilling valve block inside the PT-FC2.
