Omnitek S-Flow IV+ Automatic Houillon Viscometry System

Descriptions

The latest generation of S-flow builds on the strong foundation of its predecessors to offer the ultimate in automatic viscometry testing of Newtonian samples, such as petroleum products. The system offers all the tried and tested advantages of a Houillon-type tube design, such as short process times, small sample volume and low solvent consumption, but now also includes an optional auto-sampler to allow for fully unattended operation. Everything is controlled from a central software interface that takes care of result storage, auto-sampler control, calculations and much more. The new S-Flow IV+ consists of two bath systems with two tubes in each bath, and it provides dual temperature measurements in an extremely compact package. Other options include dual solvent cleaning and integrated duplo testing, which obtains two flow time determinations with only one sample injection.
