Borosil® Reusable Heavy Duty Test Tubes are constructed from mechanically strong, low-extractable borosilicate glass. Thick, uniform walls, excellent thermal shock resistance, and rounded bottoms mean these tubes can be used and reused without issue. Each Borosil® Graduated, Stoppered Test Tube is graduated in metric units for greater accuracy, and comes with a standard taper glass stopper for sealing the tube with ease. Borosil® Reusable Heavy Duty Test Tubes with Graduations and Glass Stoppers are available in a variety of sizes ranging from 10mL (17mm x 160mm) to 100mL (34mm x 210mm).
