Stoppers
Leak-proof, solid stoppers seal bottles, flasks, vials, and even tubing to prevent liquids and gases escaping. Multi-hole styles provide the limited flow stability conditions desired in order to prevent air bubble build up. With a slightly tapered design, different diameter sized stoppers are inserted in labware for a snug fit that still allows easy removal. The closures are manufactured in different materials for accurate resistance to harsh contents and can maintain vacuum atmosphere.

Supplier: SciLabware
Ideally suited for use with volumetric flasks etc. Lower closed end of stopper features a 'drip-tip' to ensure adhered liquid is returned to the flask. Flat head allows stopper to be stood on end, thus preventing contamination of the ground surface.
