Product Description
Compare the viscosity of varnishes, resins and similar liquids quickly with the bubble-time method. These flat-bottomed tubes are made for ASTM D1545-style testing, where bubble rise time indicates relative viscosity. They are a fast, low-cost screening tool for coatings and resin labs.
This listing is for Kimble catalog number 46463-1075: KIMAX Varnish Viscosity Tube, Case of 144. Each tube is borosilicate glass 5.1 with a 10.75 mm inside diameter and a flat bottom. Durable white ceramic enamel lines sit at 27, 100 and 108 mm from the outside bottom to standardize fill height and timing. Supplied in cases of 144. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
