VAS Fully automatic sampler

Viscosity auto-sampler

The sampler based on the Combi-PAL sampler of CTC offers the convenience of full automation at the highest sample throughput rate as an add-on to the two-station (VAS 1/2) or four-station (VAS 1/4) measuring systems. Depending on the size of the sample bottles, up to 63 samples can be processed in one session. Heated sample racks with similarly
thermostated syringes guarantee trouble-free measurement of hot polymer solutions or oils without the samples cooling down over the course of the process. The system is controlled using a special PVS program which permits the safe application-specific allocation of the measurement samples to the matching glass viscometers, e.g. through direct “drag & drop“ from the task list which was generated during sample preparation. The measurement of the samples is done in the S 5 measuring stand,while the cleaning of the glass capillary viscometers and dosing syringes is done via suitable VRM modules.
