Stoppers

Our SIBATA ST Glass Stoppers meet ASTM E-675 Specifications. These stoppers are lightweight yet very strong to reduce chipping and breakage, thus minimizing replacement costs. The flat top design allows the stopper to stand on its head, which frees the users hand and minimizes potential contamination. Interchangeable with other common flask stoppers and fit all standard labware of comparable ST size.

Our SIBATA ST Polyethylene Stoppers meet ASTM E-675 Specifications. These stoppers are made with closed bottoms and polyethylene, which conform to ST stopper dimensions. The three unit rings on the base provide an efficient seal. Can be used in place of conventional ST flask stoppers.

Our solid laboratory black natural rubber stoppers stay pliant over a long period and withstand laboratory conditions without hardening. Stoppers retain resiliency even after repeated autoclaving. Each stopper has its size in raised figures on top.
