Leakproof, inert, non-pyrogenic, and virtually unbreakable tubes! Non-Sterile Microcentrifuge tubes do not include caps. 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. Color Coded: O-Ring Screw Caps available (not included) in a variety of 10 different colors. Use with cap model # BP-4215R or BP-4215RSL.
Conical, 2.0mL, upright polypropylene, Natural Micro Centrifuge Tubes. 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! Use with cap model # BP-4215R or BP-4215RSL.
Microcentrifuge Tube Benefits:
Sample Integrity: O-ring creates a positive seal that prevents leaking during processing, storage, or transport. Tube is made of inert virgin-polypropylene copolymer, to minimize the risk of altering samples.
Universal Use: Accommodates all fixed angle head microcentrifuges (0.5mL and 2.0mL upright models require adapter Cat. No.4212). Will withstand maximum G-forces of all current microcentrifuge instruments.
Safe and Reliable: External threads minimize contamination, material hang-up and loss. Screw cap is made of the same material as tube.
Convenient: Molded ridges on tubes match serrations on racks (Cat. No. 4214), so tubes may be opened with one hand. Upright models stand without a rack. Seamless, conical design lets you extract all of sample with pipette or syringe. Transparent polymer lets you see your sample clearly.
Color Coded: O-Ring Screw Caps available (not included) in a variety of 10 different colors. Use with cap model # BP-4215R or BP-4215RSL.
Sturdy and Reusable: Ideal for freezer storage, boiling, autoclaving and irradiation.
The extraordinary strength, safety and reliability of the Screw-Cap Microcentrifuge Tube lets you perform procedures that simply can't be done with other tubes. Spin it, store it, transport it (even by air). Boil it, irradiate it, immerse it in the vapor phase of liquid nitrogen, it will stand up to the test! Inside the Screw Cap, our ethylene propylene O-Ring forms a secure and leak-proof seal. The Screw-Cap Microcentrifuge Tube's square threads won't strip-and they're on the outside of the tube, so you minimize the risk of contaminating your sample-or letting it contaminate you.
