SI Analytics - Viscometry Autosampling system - AVS® Pro III

The AVS® Pro III automatic sampler is a PC-controlled, fully automated instrument for the determination of the viscosity, viscosity number, intrinsic viscosity etc.

In spite of the high sample throughput, AVS® Pro III provides maximum accuracy and reproducibility. Furthermore, working with the automatic sampler is easy and allows unattended 24 hour operation.

The AVS® Pro III, meanwhile in its 3rd generation with many improvements, has proved itself especially for quality control of polymers. Worldwide, most producers of polyamide, polyesters and other polymers trust in the AVS® Pro III. And increasingly, also many polymer processing companies are using the AVS® Pro III in their QC.

Depending on application and customer’s demands, the instrument can be delivered in various configurations:

  • in general 2 to 4 measuring positions
  • macro or micro dosing modul, depending on viscometer types
  • two rinsing options: using next sample or rinsing agent with subsequent drying
  • variable waste system
