The UFIT Viscosity-Systems
UVS®, UFIT Viscosity Systems for automated determination of liquid viscosity of polymers and kinematic viscosity of petroleum products
due to ASTM D 665 in capillary viscometer.
The flow time is optically measured with an exactness in milliseconds. We also measure the exact flow time per thermistors in case of opaque appklications, like used motor oil.
You can find in our UVS® systems solvent and acid resitant pumps and valves, to ensure to measure any kind of application.
The modular concept of our UVS® systems allows customer specific configurations, like baths with different temperature, sampling und multi channel measuring.
Der measuring process like pretemperature, measuring, suction, rinsing and drying, plus the analysis and archiving of the measured data happens automatedby our software VisKey,
which runs on a Windows PC with USB-
interface. The software supports up to 8 independent channels at same time !!!
can measure the viscosity of following polymeres:
Polyamide (PA), Polyester (PET / PBT / PCT / PEN), Cellulose acetate (CA),
Polyvinylchlorid (PVC), Polyethylen (PE / PP), Polymethylmethacrylate (PMMA),Pulp, Cellulose, Polyisobutene (PIB),Polycarbonate (PC), Polystyrene (PS), Polyphenylene sulfide (PPS),watersoluble Polymers, Enzyme kineticsOf course the system can measure also other polymers.
can measure the viscosity of folowing oils (transparent, colored oder opaque):
crude oils base oils transmission oils
distillate petrol E20 motor oils
kerosene biodiesel coolants
jet fuel paraffin used motor oils
residual fuel oils petroleum photoresists
synthetic oils wort blood
calculate in situ the result and support a variety of formulas.

and also individual, customized formulas are supported by our formula editor.
are manufactured with chemical resistent parts which could have contact with the sample. That's why we can use following solvents:
formic acid, sulfuric acid, dichlormethane, chloroform,
m-cresol, phosporic acid, toluene, isooctane,
phenol, tetrachloroethane, water, sodium chloride,
dichlorobenzene, dichloroacetic acid, trifluoracetic acid, acetone,
o-chlorphenole, trichlorophenole, methanol, ethanol,
nitrocellulose, Cuen, EWNN, CED solution
cyclohexanone, THF, Decahydronaphthalene, Hexane,
dimethylketene, NEP, NMP, Petrolether
and of course other solvents...
are used in R&D and in production. The measurments can be done in accordance to
