The LabPak viscometer is an easy-to-use mechanical device that utilizes a piston to measure time-of-fall up to 20 seconds, with accuracy to within 0.1 second. The unit is capable of measuring changes in viscosity as small as 0.02 CPS, depending upon the water- or solvent-based liquids being measured. Featuring a removable sleeve that accommodates samples down to 6 ml, as well as larger samples in beakers, the viscometer consists of all stainless steel wetted parts and open rod construction. Easy to clean, this laboratory viscometer works under atmospheric pressure, has a three-way 24 VDC air valve, and requires 40 psi dry air and 100/240 VAC.
