Reaction tubes

Our polystyrene or polypropylene reaction tubes have a two-position vent stopper. Available in a range of sizes and different pack sizes, with or without graduations.

The two-position vent stopper has two primary functions:
  1. When the stopper is pressed lightly onto the tube, the contents of the tube are uniformly ventilated
  2. When the stopper is pressed firmly onto the tube, an airtight seal is achieved.
