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:
- When the stopper is pressed lightly onto the tube, the contents of the tube are uniformly ventilated
- When the stopper is pressed firmly onto the tube, an airtight seal is achieved.
