Cork to Fit Conical Flask is a tapered sealing component made from natural or synthetic cork, designed to provide a snug, airtight closure for conical (Erlenmeyer) flasks. These stoppers are essential for laboratory procedures requiring the containment of samples, prevention of evaporation, or protection from airborne contaminants. Their compressibility, resistance to mild chemicals, and reusability make them ideal for both general lab work and industrial testing environments. The corks are precisely sized to fit standard flask openings, ensuring compatibility with a wide range of flask volumes.
