Microcentrifuge Tube, Conical 2 ml with Caps, Sterile, case/500

Leakproof, inert, non-pyrogenic, and virtually unbreakable tubes!

Sterilized by gamma radiation, our advanced cryogenic microcentrifuge tubes have an O-Ring screw cap for a positive, leak-proof seal. They're designed for safe storage of cells or biological fluids in the vapor phase of liquid nitrogen or any mechanical freezer. They're ideal for sperm, serum or blood specimens, micro- biological cultures, cell cultures, and hazardous or valuable samples.

Screw Caps with O-Ring included!

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

Sterilized cryogenic microcentrifuge tubes are made of a virtually unbreakable copolymer.

• Sample Integrity- Sterilized by gamma radiation. Non-toxic and non-pyrogenic. Included Screw cap with internal O-ring forms a leak-proof seal during processing and storage.
