DFC 70 including PT-DT70 Bath

Semi Automated Dissolution Testing

Whenever automated sampling is required the PTFC-2 Fraction Collector together with a pump offers an ideal choice. The control of the PTFC-2 Fraction Collector with respect to sampling times, dosage volumes, refilling and pump drive is done via the keyboard of the PTFC-2. Enter sampling times, interval time, and sampling volume at the keyboard of the PTFC-2 and connect the system components together for a semi automated operation.
Correctly positioned sampling tubes which pass through the drive head of the PT-DT70, 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 PTFC-2 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, In-Situ Sampling Probes, PTFE tubing installation, 8-channel Peristaltic-, Syringe- or Piston Pump, and a PTFC-2 Fraction Collector. Refilling can be automated, too using a 16 channel pump and a refilling valve block inside the PTFC-2.
