Rubber Stopper, 1 Hole for Conical Flask

A rubber stopper with one hole is a versatile laboratory tool used to seal conical flasks. These stoppers are typically made from natural rubber or silicone, offering elasticity and a good grip on the flask’s rim. The single hole in the stopper allows for the insertion of tubes, thermometers, or other equipment while maintaining a closed system within the flask.

Key Features:

• Material: Natural rubber or silicone (depending on the brand)
• Design: Conical shape with a single hole in the center
• Function: Creates an airtight seal on conical flasks
• Applications: Holding liquids, preventing evaporation, introducing additional equipment

Benefits:

• Leakproof seal: Ensures contents remain within the flask and prevents contamination.
• Versatility: Single hole allows for various setups with tubes, thermometers, etc.
• Durability: Rubber or silicone construction provides long-lasting use.
• Cost-effective: Affordable solution for sealing conical flasks.

Choosing the Right Size:

Rubber stoppers for conical flasks come in a range of sizes to fit different flask diameters. It’s crucial to select a stopper that matches the specific size of your flask to ensure a proper seal. Size designations typically follow a numbering system (e.g., #5, #6, #8) or millimeters (e.g., 24/40). Refer to the manufacturer’s sizing guide or measure your flask’s opening diameter to choose the correct stopper.
