Viscometer, Cannon-Fenske U-Tube Type, BORO 3.3 Glass, Calibrated at 40°C

Description

The Viscometer, Cannon-Fenske U-Tube Type, 40°C BORO 3.3 Glass, also known as calibrated Cannon-Fenske glass viscometers, are designed for measuring the kinematic viscosity of transparent Newtonian liquids. These viscometers are made from 3.3 borosilicate glass and are listed as autoclavable, supporting routine laboratory cleaning and preparation where suitable approved procedures are followed. The Cannon-Fenske U-tube design is commonly used for transparent liquid viscosity testing, particularly for petroleum products, lubricants and compatible laboratory samples tested under controlled conditions. This range is listed for measurement according to ASTM D445 and ISO 3104, with specifications listed as conforming to ASTM D446 and ISO 3105.

Each viscometer is supplied with a certificate of constant and is listed as calibrated at 40°C. Constants at different temperatures are available by special order at additional cost. Available sizes include 25, 50, 75, 100, 150, 200, 300, 350, 400, 450, 500 and 600, covering listed viscosity ranges from 0.5 to 20,000 mm²/sec (cSt). The minimum sample volume is listed as 7 mL, supporting controlled viscosity measurement when used with the correct procedure, suitable bath setup and compatible timing method. Users should confirm the correct Cannon-Fenske size, viscosity range, approximate constant, test temperature, sample volume, liquid compatibility and method requirements before ordering or use.

Glass viscometers should be handled carefully. Avoid mechanical shock, sudden temperature changes, abrasive cleaning tools, excessive force and unsupported handling during filling, use or cleaning. This product is intended for laboratory or educational settings only and should be used under appropriate laboratory or teacher supervision. This item is supplied as the selected Cannon-Fenske U-tube viscometer with constant certificate only. Stand, clamp, timer, pipette filler, thermometer, viscosity bath, liquids, cleaning accessories and worksheets are not included unless specified separately.

LabChoice Australia supplies Cannon-Fenske U-Tube Viscometers with Constant Certificates for laboratories, university teaching laboratories, testing facilities and training environments requiring calibrated BORO 3.3 glassware for transparent liquid viscosity measurements.
