Frequently Asked Questions
Which tubes do these flange plug caps fit?
They are designed for 17mm-diameter test tubes and standard 15mL centrifuge tubes. The flange plug pushes into the tube mouth to form a secure friction seal.
Are these caps sterile?
No. These caps ship non-sterile. If your protocol requires sterility, validate an autoclave or other sterilization method against the polyethylene material before use.
What is the difference between SKU 6263C and 6263C-PACK?
Both are the same 17mm natural polyethylene flange plug cap at the same list price. They are alternate manufacturer catalog references for the bag-of-1000 unit.
Can these caps withstand organic solvents?
Polyethylene handles aqueous buffers, dilute acids and bases, and alcohols well, but resistance to acetonitrile is limited and aromatic or chlorinated solvents are not recommended.
