HVU 481 - Automated Ubbelohde Viscometer

Test Methods

ASTM D445, ASTM D446, DIN 51562, IP 71, ISO 3104, ISO 3105, GOST 33

 

Description

The Herzog's HVU 481 is an automated viscometer system that offers the utmost in stability, ease of use, repeatability, and high sample throughput. It simultaneously tests up to two samples using standard Ubbelohde-style capillary tubes. It offers true stand-alone operation with exceptional bath temperature range and stability. Near-infrared (NIR) or NTC thermal meniscus detection systems precisely measure flow properties of even the most challenging sample types, while an automatic tube cleaning system incorporates Kalrez(tm) seals to withstand aggressive solvents such as toluene or acetone. Complete cycle time, including automated cleaning, is 30 to 40 minutes. Results can be exported immediately or on-demand to a printer or LIMS. Add the powerful Herzog Laboratory Information System (HLIS) Windows-based software for enhanced operation and data management.
