Product Description

Designed for safe storage of cells or biological fluids in the vapor phase of liquid nitrogen or any mechanical freezer. Ideal for sperm, serum or blood specimens, micro- biological cultures, cell cultures, and hazardous or valuable samples.

The rugged, proprietary copolymer and uniform wall construction will stand up to any current microcentrifuge. Plus, tubes' external threads prevent leaking even under the pressure changes of air transport. No tube offers more security to your sample!

Sterilized Polypropylene Cryogenic Tube Benefits:

  • Sample Integrity: Sterilized by E-Beam. Non-toxic and nonpyrogenic. The included O-Ring Screw Cap forms a positive, leak-proof seal that prevents leaking during processing, storage, or transport of your microcentrifuge tubes.
  • Safe and Efficient: External thread eliminates material hangup and minimizes chance of contaminating you or your sample. Square threads won't strip.
  • Convenient: Conical design lets you retrieve your entire sample. Stand without a rack. Molded ridges on tubes match serrations on 40-Place Keyed Rack (Item# BP-4214 sold separately), so tubes may be opened and closed with one hand. Tubes fit all fixed angle head microcentrifuges (Requires adapter Item# BP-4212 sold separately).
  • Sturdy: Virtually unbreakable. Will withstand maximum G-forces of all current microcentrifuges when used with fixed angle heads.
