Stony Brook Scientific Ltd. (SBS) is the world's leading manufacturer of falling needle viscometer products in any scientific and engineering fields requiring accurate fluid property measurements. SBS viscometers are the industry standard for viscosity measurements. The company was founded in 1991, and has its corporate headquarter located in Norristown, Pennsylvania, USA. Stony Brook Scientific, Ltd. has brought together an impressive group of advisory staff members and professors from well known universities for the development of new scientific equipment. SBS's continuing goal is to be a presence in the market place as the standard for viscosity and other fluid property measurements.

Stony Brook Scientific, Ltd. (SBS) primarily manufactures scientific instruments such as the Portable Field Viscometer, Disposable Viscometer, Portable/Disposable Viscometer, High Pressure and High Temperature Viscometers, Caulking Viscometer, Controlled Needle Viscometer, High Temperature Viscometer, Ultra High Pressure Viscometer, Sealed Viscometer, Falling Needle Viscometer/Density Meter, Thermal Expansion Coefficient and Relative Sedimentation Rate Measurement Systems.

Stony Brook Scientific Ltd. viscometers are helping measure today's most challenging viscosities and fluid properties.

Accurate, reliable and cost-effective measurements of viscosities and other fluid properties are essential in product R&D and quality control.

Stony Brook Scientific Ltd. Falling Needle Viscometer can measure viscosity and other fluid properties of adhesives, aerosols, automobile fluids, blood, biomaterials, coal slurries, coatings, colloids, cosmetics, creams, dairy products, detergents, dispersions, emulsions, fertilizers, foams, fuels, gels, grease, honey, inks, ketchup, latex, lubricants, mayonnaise, milk, oils, ointments, paints, petroleum, polymers, proteins, pulp, resins, shampoos, slurries, soaps, solutions, surfactants, suspensions, varnish and many more fluids.

Advantages of the Falling Needle Viscometer:

No calibration required (uses gravity)
Accurate (better than 1%)
Largest viscosity range (0.1 to 108 cP)
No moving parts except a needle
Disposable (no sample contamination)
Simple operation
Easy, accurate and multiple (9) sample temperature control
Extremely low shear rate (yield stress and zero shear rate viscosity measurements)
Simultaneous measurement of viscosity and density for Newtonian and Non-Newtonian power law fluids
Relative particle settling measurement
Relaxation time measurement (time interval effect)
Minimal disturbance of sample's mechanical structure and particle size distribution with gentle needle passage and undisturbed sample near the bottom tip of the needle
