Stony Brook Scientific Ltd. offers a wide range of reliable, low-cost viscometer products to suit the custom needs of any experiment for measuring fluid viscosities. [Overlay Text with Image, use 6 product images.]

The Portable/ Disposable Viscometer (PDV-100) which features disposable sample tubes is now available!  This inexpensive manual viscometer can measure Newtonian and non-Newtonian viscosities under field conditions!

A Disposable Viscometer (DV-100)  which includes disposable sample tubes and a microprocessor-based measurement console for automatic needle falling time measurements, and viscosity and temperature displays is also available.  This viscometer greatly reduces testing time because sample tube cleaning is not required. 

The Falling Needle Viscometer (FNV-200) and Controlled Needle Viscometer (CNV-100) can easily measure liquid viscosities up to 10⁸ cP.

The High Temperature Viscometer (HTV-100) can measure liquid viscosities up to 350^oC.  Viscosities measured using this instrument can range from 1 to 10⁸ cP for both Newtonian and non-Newtonian fluids. 

The High Pressure High Temperature Viscometer (HPHTV-100) can measure liquid viscosities up to 2000 psi and 150^oC, over a range of 1 to 10⁶ cP for both Newtonian and non-Newtonian fluids.

The Caulking Viscometer (CV-100) features a disposable caulking sample tube and requires no sample tube cleaning.

Stony Brook Scientific Ltd's viscometers can measure intrinsic viscosities, zero shear rate viscosities, yield stresses, relative particle settling rates and Newtonian fluid densities.  The absolute accuracy of these viscometers is better than 1%* without any instrument calibration. The above viscometers which use the falling needle principle have been adopted as a standard by ASTM 5478-98. 

[* The portable/disposable viscometer, which is suitable for field measurements, has an absolute accuracy of better than 5%.]
