Control flow behaviour — from the flow cup on the line to the rotational viscometer in the laboratory.
Viscosity determines whether a material can be applied, how it flows out and whether it stays put on a vertical surface. It is therefore the property tested most often and most quickly — at goods inwards, before the batch is made up and continuously in production. Because it depends strongly on temperature, a reading without a stated temperature is worthless.
The flow cup measures an efflux time and is sufficient wherever the same material is repeatedly checked against itself. As soon as a material is shear-thinning — that is, changes its viscosity under shear, as almost every modern coating does — a single efflux time says too little. Then a rotational viscometer is needed, measuring at a defined shear rate and, across several shear rates, revealing the flow behaviour.
Trade names from our range. Click a name to ask Corvus — he knows the technical data and helps you narrow things down.
Data sheets, operating manuals and quotations are available on request. We quote prices individually, because configuration, accessories and the scope of calibration decide the figure.
An instrument is only worth something once its readings hold up. Calibration, adjustment, repair and operator training are handled from Aesch — the same contact, the same language.
Caw! I know every data sheet.
Corvus is an AI assistant, not a product filter: tell him in plain language what you need to measure — he reads the BYK-Gardner technical data sheets, asks back when something is missing, and only then recommends. Gloss, colour, film thickness, viscosity, physical testing and more.
He answers from the instruments' technical documents — measuring ranges, standards, specifications. Not from general web knowledge.
Describe the problem in your own words. He asks about the measuring task, substrate and standard — and only then recommends a specific instrument.
For prices, demos and quotes, the ChemServices team takes over personally.
