Simplicity, flexibility, and reliable results have made ViscoQC the new standard in rotational viscometry. It ensures the quality of your substance – from liquid to semi-solid – with an accuracy of ±1.0 % of the range in use. Its unique automatic spindle recognition in addition to magnetic spindle exchange ensures traceable, error-free measurements. It even suggests the right speed when you test an unknown sample. Test results can be reproduced anywhere in the world when the same measuring system is used.
Buy it, love it! Benefit from an exclusive 30-day money back guarantee. Buy the instrument, see how it works, and – if you don’t love it – we’ll take it back. Here’s how it works.
