Rubber stopper

The rubber stoppers selected by AllChimie provide tight sealing for standard laboratory containers: test tubes, Erlenmeyer flasks, bottles and volumetric flasks. Their standardised conical shape ensures a precise fit with common necks of scientific glassware.

Manufactured from natural or synthetic rubber, these stoppers offer good elasticity and adequate resistance to non-aggressive aqueous reagents. They are available in solid or bored versions (one or two holes) for inserting tubes, thermometers or probes into your setups.

The range includes several standard sizes to match the most common neck diameters found on your bench.

Depending on your constraints, other materials may be better suited: the silicone stopper for high thermal resistance and autoclaving, the neoprene stopper for better resistance to oils and solvents, or the plastic cap for tight screw closure on bottles. All are compatible with the plastic Erlenmeyer flasks from the AllChimie range.
