5011 Bulk-packed Non-sterile Cryogenic Vials Materials: polypropylene high-density polyethylene closure Economical, non-sterile version of Cat. Nos. 5000-0012 and -0020 without printing or graduations. Closures and vials are packed separay. Do not autoclave. These vials are for research use only; not for in vitro diagnosis or parenterals. 1000/bag. WARNING! Do not use cryogenic vials for storage in the liquid phase of liquid nitrogen unless correctly sealed in Nunc CryoFlex? tubing. Such use may cause entrapment of liquefied nitrogen inside the vial and lead to pressure build-up resulting in possible explosion or biohazard release. Use appropriate safety procedures as outlined in the NALGENE Cryopreservation Manual when handling and disposing of vials. Request Lit. No. 10096 or download a copy from
Ideal bottle for low-speed centrifugation of aggressive chemicals. Excellent for large-volume lipid and phenol extractions, digestions and precipitations. Resists most acids, bases and organic solvents. Autoclavable bottle rated for temperatures from -100? to +150癈. Use NALGENE sealing cap assembly (Cat. No. DS3131-0038) to run this bottle at maximum recommended speed (4,000 x g). When using this bottle in the Sorvall GSA rotor use the NALGENE centrifuge bottle adapter (Cat. No. DS3125-0250). Before autoclaving, just set closure on top of the bottle without engaging the threads. NOTE: FEP centrifuge bottle must be filled to 100% of the total capacity for proper performance.
