Herzog's automated Ubbelohde viscometers offer 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.
