These polypropylene plastic caps are compatible with our amber and clear glass diagnostic bottles which can be purchased separately. These closures are specifically designed for diagnostic applications, and offer all the advantages of an aluminum seal and stopper with the convenience of a plastic screw cap. The unique combination of a stopper and screw cap ensures excellent sealing characteristics, making them ideal for liquid reagents. Sample contents can be accessed using a syringe through the stopper or with a pipette after removing the screw cap. These plastic caps are available in black, white, red, blue, and yellow colors for the added benefit of easy sample classification and identification. Tolerances in the stoppers are maintained to +/-.010". These caps are autoclavable.
