Cork stoppers are simple yet versatile tools for science demonstrations and laboratory activities.
The natural cork has imperfections including holes. Sealing Test Tubes and Flasks: Use cork stoppers to securely close test tubes, flasks, or other glassware during experiments to prevent spills and evaporation.
The cork is safe for use with food products. Density Experiments: Use cork stoppers as floating objects to demonstrate buoyancy and density in water.
DIY Lab Equipment: Cork stoppers can be modified to hold thermometers, pipettes, or glass tubing, making them essential for custom lab setups.
