Description
The U-Tube BS/U Viscometers, BORO 3.3 Glass, also known as BS/U glass viscometers, are designed for laboratory viscosity experiments, flow time observation and educational fluid behaviour demonstrations. These viscometers are made from 3.3 borosilicate glass and are listed as autoclavable, supporting routine laboratory cleaning and preparation where suitable procedures are followed. The U-tube BS/U design is suitable for use in school science laboratories, university teaching laboratories, training environments and general laboratory settings where compatible liquids are tested according to an approved method.
These viscometers allow users to observe and compare the flow behaviour of liquids through a controlled glass pathway, supporting lessons on viscosity, kinematic viscosity, fluid resistance, flow time and temperature-dependent liquid behaviour. This range is supplied without constant certificate, so users should confirm whether a certified or constant-certified viscometer is required for their method before ordering. Available sizes include A, B, C, D, E, F, G and H, covering listed viscosity ranges from 0.9 to 10,000 mm²/sec (cSt). Each option is supplied as 1 piece per pack. Users should confirm the required BS/U size, viscosity range, liquid compatibility, cleaning method, filling technique, timing procedure and temperature control requirements before ordering or use.
This product is intended for laboratory or educational settings only and should be used under appropriate teacher or laboratory supervision. Glass viscometers should be handled carefully. Avoid mechanical shock, sudden temperature changes, excessive force, abrasive cleaning tools and unsupported handling during filling, use or cleaning. This item is supplied as the selected U-tube BS/U viscometer only. Constant certificate, stand, clamp, timer, pipette filler, thermometer, bath, liquids, cleaning accessories and worksheets are not included unless specified separately.
LabChoice Australia supplies U-Tube BS/U Viscometers in BORO 3.3 glass for school science laboratories, university teaching laboratories and training environments requiring practical glassware for viscosity and flow time experiments.
