Screw Caps for G-Tube MicroCentrifuge Tubes with O-ring, 1000/pk
| Sterilized by gamma radiation, our advanced cryogenic tubes have an O-Ring screw cap for a positive, leakproof 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, microbiological cultures, cell cultures, and hazardous or valuable samples. 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! |
