OmniTek has just launched its new fully automated viscometer, called ‘U-VIsc 200’. This instrument fully complies to ASTM D445, has 2 independent baths with 2 Ubbelohde like glass viscometer per bath. In addition per bath a rotating autosampler suitable to 2 x 16 samples.
Sample introduction via pressure or suction. Automated cleaning. High troughput, highest compared to competitors.
The OmniTek U-VIsc 200 automated viscometer.
The U-VIsc 200 viscometer combines several unique features, making it the instrument of choice in many applications, ranging from QC to R&D to used oil analysis. While offering full compliance with ASTM D445/446, the specially designed viscometer tubes cover a 100-fold range, so a single tube can cover a range of 1-100, 2-200 mm2/s etc.
The tubes are based on the well-known and proven Ubbelohde design. Through modification the main advantage of this design (accuracy) is maintained, but the main disadvantages (sample and solvent consumption, ease of use) negated. The modified tubes only require 8-12 ml. of sample and approx. 15-20 ml. of solvent for cleaning. Available with 1 or optional 2 solvent cleaning, the instrument measures kinematic viscosity between 0.5 and 5,000 mm2/s.
The instrument is compact, saving costly bench space. It is fitted with 2 independent baths, which each contain 2 100-fold viscometer tubes. Sophisticated temperature control ensures that measurements are carried out well within ASTM D445 requirements. Each bath features a 32-position sampling tray (16 samples per tube), allowing completely unattended operation. Depending on the viscosity of the sample, the instrument can process up to 40 samples per hour, satisfying even the needs of high volume commercial labs running several hundred samples per day. All measurement data is stored on the connected PC and can be exported directly to LIMS or spreadsheet software.
