These grade tapered cork stoppers are an excellent choice for general laboratory use. They are effective for both liquid and solid mediums, and offer light weight, resilience and compressibility. Chemically inert and moisture resistant. Cork stoppers can be used to close test tubes and lab glassware, such as Erlenmeyer Flasks, Florence (Boiling) Flasks, and Filtering Flasks, to prevent liquid from escaping.
