The Viscotek DSV measures the relative viscosity of dilute polymer solutions using a two capillary viscometer design. The system is fast, accurate and precise. It is available with several automation options and has the ability to self-calibrate and self-clean for reliable, operator-independent viscosity measurements.
The dual capillary design of the Viscotek DSV measures the difference in solution viscosity between the solvent and the sample directly and simultaneously. This eliminates any differences due to temperature change, calibration or operator.
Since it uses less solvent than traditional glass-tube systems, the DSV offers a more economical, environmentally friendly and safe method to measure polymer solution viscosity.
Measure the relative viscosity of solutions containing samples from low molecular weight resins up to high molecular weight polysaccharides and polyolefins. Typical applications include polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyamides (nylon), synthetic rubber (EPDM), hyaluronic acid, and polyolefins (PE/PP). Robust design and resistance to aggressive solvents make it ideal for lab and QC environments. Multiple system options to suit a wide range of different solvent viscosities. Manual, auto-sampling and auto-preparative options available. ASTM defined measurements of relative viscosity. High temperature option for solutions up to 160°C.
