Viscometers measure viscosity fluid flow or stress resistance. General terms, viscous fluid "thickness" a strong interest in physical property liquids, slurries and pastes manufacturers. Viscosity is an important characteristic of food products, paints, cleaners, adhesives, polymers, oil, and pharmacy. Many industry-viscosity liquid products to produce an end.
Dozens of viscometer types use in academia, industry and basic research and will cost about $ 100 for a simple mechanical viscometers automated means $ 15,000. Rheometers, which measure the viscosity and related properties, can cost as much as $ 200,000.
At the lower price range is the U-tube and cannon-tube viscometers Fenski find schools, colleges, and some industries. Another simple design, with the area covered by the piston, rolling the ball, and the oscillating piston viscometers. This is not the truest sense of the demands pourable liquids.
Complex used in the processing industry, the vibrational and rotational viscometers viscometers. The latter works on the principle that energy must be applied to the blade spindle rotates through the fluid to overcome the fluid resistance. That energy is proportional to the fluid viscosity. Rotational viscometers require that the test sample pourable.viscosity of the overall performance index. Polymer scientists have used the plastic viscosity of acid concentration.
Upper class viscometers can be connected and controlled via computer, or readings can be taken directly to the front panel display. Some industries benefit type viscometer. Dyes and pigments industry chooses Stormer viscometer, which uses the paddles on the rotor is immersed in the product. In addition, the laboratory uses a resin bubble viscometers, which is the length of the bubble out of the lakes, the oil companies prefer Stabinger viscometer, which employs a rotating cylindrical tube.
Viscometry old technique, but the producers, and align more complex electro-mechanical rotational viscometers core technology has not changed much.
What is different, "says Steven ATS RheoSystems Colo (Bordentown, NJ), president of user experience. "Twenty years ago, the majority of users of academic specialization or viscometry rheology. Today, professionals have been replaced by co-workers.
Biotechnology and pharmaceuticals, proteins, and buffer viscosity is one of a number of quality checks, drinks, sugar content and viscosity of the overall performance index. Polymer scientists have used the plastic viscosity of acid concentration.
The latter works on the principle that energy must be applied to the blade spindle rotates through the fluid to overcome the fluid resistance. That energy is proportional to the fluid viscosity. Rotational viscometers require that the test sample pourable.
Viscosity measurements are usually carried out in dilute solutions of various concentrations. Different strengths of polymer solutions viscosity measurements, for example, provides estimates of secondary properties such as intrinsic viscosity-molecular weight and chain length.
Viscosity is related solute concentration, and one of the most useful research and product development in the physical measurements. Liquid viscosity generally increased levels of particulate Solutes in water with sugar. But completely miscible and non-liquid reaction mixture viscosity is usually somewhere between the components of the viscosity.
Useful viscometer / Rheometer features that buyers should be aware of the temperature control of spindle rotation speed control, sample holders, and ease of use.
