Borosil Test Tubes With Rim 10*75,800/CS

Borosil® Reusable Heavy Duty Test Tubes are constructed from mechanically strong, low-extractable borosilicate glass. The flame-polished, beaded rim confers strength, preventing chipping and cracking. Thick, uniform walls, excellent heat resistance, and rounded bottoms mean tubes can be reused without issue. Borosil® Reusable Heavy Duty Test Tubes comply with ISO/DIN 4142. Available in a variety of sizes from 3mL (10mm x 75mm) to 170mL (38mm x 200mm). In collaboration with Borosil Glass Works, Foxx Life Sciences is proud to bring the outstanding quality of Borosil® Type 3.3 Borosilicate glassware to North America for the first time. Manufactured from the same USP Type 1 borosilicate glass that North American scientists have come to trust, Borosil® Laboratory Glassware offers unparalleled mechanical strength, clarity, and reliability at competitive prices. And thanks to a unique annealing process, Borosil® Glassware is stress-free and incredibly resistant to thermal shock.
