Description
The Viscometer, U-Tube Reverse Flow, BS/IP/RF, BORO 3.3 Glass, also known as BS/IP/RF reverse flow glass viscometers, are designed for laboratory viscosity experiments, flow time observation and fluid behaviour testing. 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 reverse flow U-tube design is suitable for viscosity testing workflows where compatible liquids are measured through a controlled glass capillary pathway according to the approved laboratory method.
This range is supplied without constant certificate, so users should confirm whether a constant-certified or calibrated viscometer is required for their testing procedure before ordering. Available sizes include 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11, covering listed viscosity ranges from 2 to 300,000 mm²/sec (cSt). These viscometers are suitable for laboratories, school science laboratories, university teaching laboratories, training environments and general viscosity testing workflows involving compatible liquid samples. Users should confirm the correct BS/IP/RF size, viscosity range, liquid compatibility, cleaning method, filling technique, timing procedure and temperature control 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 reverse flow U-tube BS/IP/RF viscometer only. Constant certificate, stand, clamp, timer, pipette filler, thermometer, viscosity bath, liquids, cleaning accessories and worksheets are not included unless specified separately.
LabChoice Australia supplies Reverse Flow U-Tube BS/IP/RF Viscometers in BORO 3.3 glass for laboratories, university teaching laboratories, school science laboratories and training environments requiring practical glassware for viscosity and flow time experiments.
