A New Viscometer
A viscometer is described, particularly adapted to the measurement of colloidal solutions and physiological liquids (serum, blood), which, although doing away with the capillary tube (which is difficult to handle and to clean), requires less than 1 cc. of liquid. The readings are rapid, from 30 seconds to 1 minute. The temperature is easily controlled and varied. The range is considerable and m...
متن کاملOscillating viscometer--evaluation of a new bedside test.
A viscometer for bedside blood measurements was developed, consisting of an oscillating resonator probe mounted directly into a disposable vacutainer tube for blood withdrawal. It was tested in vitro on blood samples with variable hematocrits (20-60%), increasing fibrinogen concentrations (0-20 g/l), increasing concentrations of an admixed radiographic contrast medium and erythrocyte suspension...
متن کاملThe Micromagnetoflowcell - A Microfluidic Viscometer
An experimental micromagnetoflowcell viscometer was fabricated to enable viscosity measurements for microscopic quantities of liquid. The device uses measurement of the terminal velocity of superparamagnetic microparticles to determine the fluid properties. Motion of these particles is controlled by the magnetic field generated from microscopic electromagnetic loops. Analytical modelling has be...
متن کاملMinute Volume Viscometer
In the field of pharmaceutical research, injectable treatment therapy is currently one of the most highly examined methods of drug delivery. The continuation of this research is highly dependent on knowledge of fluid properties, specifically loss and storage modulus. Most drugs in the developmental stages of this method are extremely expensive and limited in quantity. Currently, devices that me...
متن کاملA Poiseuille Viscometer for Lattice Gas Automata
A b stra ct . Lattice gas automata have been recently proposed as a new technique for the numerical integration of the two-dimensional Nav ier-Stokes equation. We have accurately tes ted a stra ightforward var iant of the original model, due to Fr isch, Hasslacher, and Pomeau, in a simp le geometry equivalent to two-dimensional Poiseuille (Cha nnel) flow dr iven by a uniform body force. The mom...
