SPS’s complete line of bottle stoppers offers the customer a high-purity option to standard gum rubber, neoprene, and black SBR stoppers. Manufactured from healthcare-grade, platinum-cured silicone, SPS’s stoppers meet UPS Class VI standards for use in Pharmaceutical, Bio-Tech, Laboratory, and Food applications. Unlike standard laboratory stoppers, SPS silicone stoppers will not spillate, crack, or leach fillers.

   SPS stoppers are offered in lab-style, tapered design as well as custom tops to fit most common high-purity screw cap bottles. All products are manufactured with high-purity silicone and can be cored or molded with integral dip tubes. These options help create a closed, high-purity system and give the user the flexibility to work with most process components and maintain cGMP standards.
