RG® Borosilicate Ostwald Viscometers — Pack of 5

PRODUCT INFORMATION

About this product

This pack contains five college-pattern Ostwald viscometers made from borosilicate glass. The instrument uses timed liquid flow through a capillary section to compare or determine viscosity under a defined method. A five-piece pack is useful for teaching batches, multiple laboratory stations and institutions keeping replacement glassware available.

Students and laboratory buyers may search for this instrument as a glass viscometer, capillary viscometer or laboratory viscosity tube. Reliable work requires a clean instrument, a controlled test temperature, correct filling and consistent timing between the specified marks. The viscometer is approximately 7 inches long; users should confirm that their holder, bath and selected method are suitable before beginning the experiment.

Five matching instruments allow a teacher to equip several workstations or let a laboratory repeat measurements with separate samples. Results depend on preparation and technique, so users should remove residues, avoid air bubbles in the capillary path and follow the calculation and cleaning instructions used by their institution.
