Name: S-flow IV⁺ Kinematic Viscometer
The latest generation of new S-flow builds on the strong foundation of its predecessors to offer the ultimate in automatic viscosity testing of Newtonian samples such as petroleum products.
It is the ideal system for used oil analysis labs that need to test a wide range of lubricant viscosities.
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 autosampler.
All controlled from a central user interface that takes care of result storage, autosampler control, VI calculations and much more.
It complies fully with ASTM D7279 and as such, provides full correlation to ASTM D445.
The new S-flow IV+ consists of a 2 bath system with 2 tubes in each bath, providing a total of 4 tubes.
The baths were designed to work independently, making it possible to use both baths at the same temperature, or at different temperature, ranging from 20°C to 120°C.
Other options include dual solvent cleaning and integrated duplo testing which obtains 2 flow time determinations with only 1 sample injection.
