Frequently Asked Questions
What tubes do these caps fit?
They fit 17 mm round tubes and standard 15 mL centrifuge tubes. The flange plug presses into the tube opening for a snug interference seal.
Are these caps sterile?
No. The 6263R caps are supplied non-sterile and are intended for general laboratory storage, sorting, and transport rather than aseptic applications.
Can these caps withstand centrifugation?
Press-fit flange plugs provide a friction seal, not a sealed leak-proof closure. Validate retention for your rotor and g-force before relying on them under high-speed centrifugation.
What material are the caps made from?
They are molded from polyethylene, offering good resistance to aqueous buffers, dilute acids and bases, and alcohols, with limited tolerance to acetonitrile and aromatic or chlorinated solvents.
