Wheaton® I-Loc™ Diagnostic Bottle Screw Caps with Bromobutyl Stopper

The Wheaton I-Loc™ screw cap with a gray bromobutyl stopper is designed for use with diagnostic bottles. This cap eliminates the use of a separate aluminum seal and rubber stopper. The unique combination of a stopper and screw cap ensures excellent sealing characteristics making them ideal for liquid reagents. The contents can be accessed using a syringe through the stopper or with a pipette after removing the screw cap. Can be autoclaved/sterilized. Cap Size: 20-400. Cap Material: Polypropylene (PP).
