VWR® Pure Gum Rubber Stopper

These stoppers maintain softness and flexibility for laboratory and food processing use. They are resilient and withstand repeated autoclaving, ensuring safety in food applications. Made from pure gum amber rubber with less than 0.25% free sulfur, they are food-grade compliant. Their lower density compared to standard black rubber stoppers provides food manufacturers with about 20% more stoppers per pound, making them an efficient choice for reliable food packaging and processing.
