The extraordinary strength, safety and reliability of our Screw-Cap tube lets you perform procedures that simply can't be done with other tubes Boil it, irradiate it, immerse it in the vapor phase of liquid Nitrogen. Inside the screw cap, an ethylene propylene O-Ring forms a secure and leak-proof seal.
Compliance: Certified RNase-, DNase-, DNA-, and pyrogen-free
Convenient - Molded ridges on tubes match serrations on racks so tubes may be opened with one hand. Upright models stand without a rack. Seamless, conical design lets you extract all of sample wit pipette or syringe. Transparent polymer lets you see your sample clearly.
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.
Our Screw-Cap tube is ideal for any sample-processing or storage application imaginable-and especially for working with valuable or hazardous cells and materials.
Universal use - Accommodates all fixed angle head microcentrifuges Will withstand maximum G-forces of all current microcentrifuge instruments.
Safe and Reliable - External threads minimize contamination, material hang-up and loss.
Sturdy and Reusable - Ideal for freezer storage, boiling, autoclaving and irradiation
