Analytical Instrumentation
U-Visc kinematic viscometer
The Omnitek U-Visc
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/D446, the specially designed viscometer tubes cover a 100-fold range.
The capillary tubes are based on the well-known and proven Ubbelohde design. Available with single or dual solvent cleaning, the instrument measures kinematic viscosity in lubricants between 0.15 and 25,000 mm2
/s.
Designed to be versatile and flexible, yet easy to use. Different models are available ranging from 1 bath with 1 or 2 tubes, up to 2 baths with 1 or 2 tubes per bath, where each bath works independently. Each bath features a sampling tray with 16 samples per tube, allowing completely unattended operation at different temperatures. Depending on the viscosity of the sample, the instrument can process up to 12 samples per tube per hour, leading to a maximum capacity of up to 40 samples per hour, satisfying even the needs of high volume labs running several hundred samples per day. An optional sample preheater allows processing samples such as waxes and heavy fuel oils as well.

S-flow automated Houillon viscometer by Omnitek BV The S-flow range of instruments consist of compact, bench-top automated viscometry systems for the
analysis of Newtonian fluids. It complies fully with in ASTM D7279 and as such, has a direct correlation with ASTM D445. It is the ideal system for used oil analysis labs that need to test a wide range of lubricant viscosities. Quick analysis time, small sample size and low solvent consumption, combined with extreme ease of use and reliability make it the instrument of choice for many of our world-wide users.
The S-flow system is a self-contained viscometer system that consists of an accurately controlled thermostatic bath and a control touchscreen. Different models are available with either 1 or 2 baths, each of which contains 4 Houillon style tubes. Highly accurate optical sensors detect the flow of the sample through the viscometer tubes to obtain flow time results with 0.001 sec. precision. All measuring viscometer tubes function fully independently of each other allowing for very high throughput.
Additional parameters such as tube constants and cleaning cycle are also controlled by the operator. Only requiring 0.3 ml. of sample, the system performs the measurement very quickly, allowing a throughput of up to 80 tests per hour per bath. Options include dual solvent cleaning and integrated duplo testing which allows the operator to perform 2 flow time determinations with only 1 injection.

The instrument was especially developed for demanding applications of high temperature and high viscosity products such as vacuum residue, additives, crude oils, waxes, heavy fuel oils, polymers, asphalts, etc. Because of the problems associated with heating, sampling, measuring and cleaning these types of samples, users were forced to resort to manual processing, which is a long and tedious process.

users a way of automatically measuring these types of samples, resulting in very substantial time savings. By implementing specially designed duplo measurement tubes based on the proven Ubbelohde viscometer type, the precision of the obtained results far exceeds requirements in ASTM D445 and D2170. An innovative cleaning system ensures that even the toughest samples are cleaned effectively from the inside and outside of the tube, preventing any cross-contamination.
