Description_x000D_ General description_x000D_ Tubes have been chemically strengthened to achieve a greater mechanical strength than standard borosilicate centrifuge tubes. These tubes can be centrifuged up to 13,100 RCF when used with an accessory rubber adapter sleeve in a 50 mL rotor cavity. They can withstand temperatures up to 300°C. Always discard the rubber adapter if a tube has broken in it._x000D_ Legal Information_x000D_ KIMBLE is a registered trademark of DWK Life Sciences_x000D_ Kimax is a registered trademark of Gerresheimer Glass, Inc.
