DFC 100 including PTWS 100 Bath

Whenever automated sampling from a Dissolution Bath 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 or testing method filing system of the PTWS 100 dissolution bath. Enter sampling times or call the required method 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 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 analyser and either manually injected or transferred to an auto-injection system.
A typical semi automated DFC 100 dissolution test system is composed of the following instruments:
PTWS 100 Dissolution Bath, PTFE tubing installation, 8 channel Peristaltic-, Syringe- or Piston Pump, and a PTFC-2 Fraction Collector. Media Refilling can be automated, too using a 16 channel pump and the refilling valve block inside the PTFC-2.
