Polypropylene screw caps are supplied in four basic types: caps without O-rings, looped caps without O-rings, caps with O-rings, and looped caps with O-rings.
The O-ring closure is formulated and manufactured from a special compound resistant to chemicals such as anhydrous ethyl alcohol, purified ether, hexane, acetone, chloroform, acetonitrile, 40% trifluoroacetic acid solution, and other chemicals used in most laboratories. The caps have extra long lips to help protect samples and ribs to allow one hand operation.
