LAUDA Automatic Viscosity Measuring System PVS

Product Details

The auto-sampler fills up to four viscometers in parallel with the same or different samples. A syringe draws up the sample from closed reservoirs which are mounted on a sample stand with optional thermostating capability. The syringe is automatically cleaned to prevent carry-over of a previous sample or cleaning solvent into the sample on test, a common danger with the more usual fixed tubing connections. The result is an appreciable improvement in reproducibility and accuracy. Before dosing the next sample, the VRM modules ensure thorough cleaning and drying of viscometers and dosing syringe. The sequence of the individual tests and the sample assignment are determined by the PC or can be conveniently set by the user.
