Laboratory Grade Neoprene Rubber Stoppers. Solid
Neoprene Green Rubber Stoppers are suitable for high temperature (up to 275°F / 120°C) and suitable for use with petroleum products, minerals, oils, fats, and organic chemicals. Rubber stoppers are used to seal laboratory vessels such as, Erlenmeyer Flasks, Florence (Boiling) Flasks, and Filtering Flasks, to prevent liquid from escaping. Neoprene Rubber is recommended for use where rubber would be attacked or deteriorated by reagents and solvents being used. Neoprene stoppers demonstrate good resiliency at elevated temperatures and shelf-life compare to regular rubber stoppers. Sulfur free.
