UVS® is a measure device for determination the kinematic, relative and kinetic viscosity of polymeric compounds or lubricants with a viscometer. Calculation and documentation of the determined values is done via the touchpad / display. In combination with a viscometer the UVS® can measure the flowtime till 9999 seconds with accuracy in 10 milliseconds.

UVS MD – Measuring Device

UVS® MD, the measuring device for flow time measuring of Newtonian fluids in common capillary viscometers with precision to millisecond. The UVS® MD is suitable

for all measurements of polymer solutions and mineral oils products.

UVS® NoLimits

High speed intensive cleaning and drying module by using vacuum and pressured air

UVS® NoLimits automated cleaning and half automated charging. This device controls pre-dilute and discharging of the sample, rinsing with up to 2 solvents and drying of the whole system.

The intensive cleaning procedure reaches UVS® NoLimits is responsible for full automated cleaning and semi-automated charging.  This device controls pre-dilute and discharging of the sample, rising with up to 2 solvents and drying of the whole system.  The intensive cleaning procedure reaches the complete viscometer with all parts of the system like tubes and sample needle. UVS® NoLimits also supports the sample transfer to the viscometer in a save way and avoid personal contamination of hazard substances during the filling. UVS® NoLimits is especially developed to handle samples in a wide viscosity range. Of course all parts are chemical resistant against all kind of organic solvents like acetone, chloroform and toluene. In case of using strong acids we provide a solution on request. UVS® NoLimits is suitable for Ubbelohde and Cannon-Fenske-Routine viscometers in accordance to ASTM D446 / ISO3104. For samples like used motor oils a TC-Ubbelohde is strictly recommended.

UVS® DRAIN

UVS® Drain, the device is responsible for automated cleaning. This device controls the discharging of the sample, rinsing with solvent, drying and discharging the solvent to the waste bottle. Sensor detection for a full waste bottle complies safety requirements. The cleaning process can be optimzed by configuration to save time and get best results.

SAMPLE CHANGER – SC8

UVS® SC8, the sample changer with 8 and respectively 24 positions in dependance of the sample bottle size. With integration of a UVS® SC8 the UVS® Basic becomes a fully automatic machine. The sampler can serve one or two viscometers. In case of two viscometers the filling and rinsing procedure works in an alternating operation mode. The turntable is available for common laboratory 100 ml sample bottles, 50 ml centrifugal tubes, 30 ml disposable PP beakers and 20 ml micro tubes. An adaption of individual sample vessels are possible on request. Depending on the stage of extension - 2x UVS® Basic and 4x UVS® SC8 - the system has up to 96 sample positions and can measure up to 80 samples per hour.

The rinsing of the sample transfer tube and piston pump is realized by the

module UVS®( RM supporting 2 solvents, a rinsing and a drying solvent. Rinsing with next sample is also configurable. There is a maximum of rinsing logic to avoid any carryover and saving solvent at same time.

The used valves are chemical resistant and have a lean dead volume. Sample filtration with filter backwashing is available as an option for low viscous samples. A sensor recognizes

UVS® LB -  Light Barriers

UVS LB, the Triple Detection light barrier made of PVDF.

The stand with integrated viscometer fixation is suited for all common

capillaries. Viscometers with fixing bracket are also usable. The

light barriers are working with infrared light and are able to detect certainly the meniscus pass. The third and topmost light barrier is used as "over suck" protection. For measurements with Micro-Ubbelohde viscometers this light barrier can increases the reproducibility of values through constant kept start conditions.

Additional fixation holder for Canon-Fenske Routine, Canon-Fenske

Ubbelohde, Witeg-, Paragon-, Tamson-Ubbelohde available.
