Digital Rotational Viscometer with Small Sample Adaptor

Direct-reading rotational viscometer supplied with a small sample adaptor and jacketed chamber so viscosity can be measured on roughly 15 mL instead of a full beaker.

Typical applications

  • Expensive or scarce samples
  • Pharmaceutical formulation development
  • Cosmetics and personal care
  • Adhesives and resins
  • Research and development laboratories

Conforms to

ASTM D2196ISO 2555
  • ASTM D2196—Rheological properties of non-Newtonian materials by rotational viscometer
  • ISO 2555—Plastics — Resins in the liquid state — Determination of apparent viscosity using a single cylinder type rotational viscometer

Worth knowing before you order

The small sample adaptor is supplied with these two models as standard — that, and the extra 21/27/28/29 spindles, is what separates them from the plain digital rotational viscometers, where the same adaptor is not offered. The water jacket around the chamber, however, does nothing on its own: the refrigerated circulating bath that feeds it is an optional extra and a separate line item, and small samples reach room temperature faster than large ones, so the jacket is not decoration. The low viscosity adaptor is also quoted separately. The per-spindle range table did not survive scanning and is not reproduced here.
