Screw Caps with O-Ring




These screw caps are designed for use with the Globe Scientific sample tubes. They are made of polypropylene, providing the same coefficient of expansion as the tubes. This along with a polypropylene inner lip ensures a leakproof seal, even at changing temperatures. The cap features a long skirt and a super-fast thread design that allows it to be removed or sealed with a single turn.

The caps are available with or without a silicone o-ring.

Both are available in a variety of colors.
