Laboratory Rubber Stopper Set Assorted Sizes

The Laboratory Rubber Stopper Set Assorted Sizes is designed for closing and sealing compatible laboratory test tubes, flasks, bottles and other glassware during routine laboratory procedures. The stoppers typically feature a tapered rubber construction, allowing them to fit securely into laboratory vessels with different neck diameters. An assorted-size set provides laboratories with multiple stopper sizes for use across different glassware rather than requiring a separate pack for every vessel. They are suitable for routine sample handling, temporary vessel closure, solution preparation, laboratory demonstrations and other applications requiring a removable closure. Depending on the supplied set, stoppers may be solid, one-hole, or two-hole. Holed versions can accommodate compatible glass tubing, thermometers or other laboratory apparatus.
