In laboratory and clinical settings, choosing the right vial stopper is essential for not only productivity, safety, and  integrity of stored solutions and medications. At Med Lab Supply, we provide a wide range of products, including a variety of high-quality vial stoppers that cater to different needs and settings.

 In this guide, we’ll explore three types of 20mm vial stoppers: the gray butyl rubber stopper, the red butyl rubber stopper, and the clear silicone stoppers, each offering different benefits.

Gray Butyl Rubber Stoppers

Our 20mm gray butyl rubber stoppers are specifically designed to seal 20mm serum vials when combined with 20mm flip-top, flip-off, or standard aluminum seals. The straight plug style of these stoppers ensures a secure, airtight seal, making them reliable for maintaining the sterility and stability of vial contents.

Red Butyl Rubber Stoppers

The 20mm red butyl rubber stoppers are another excellent option, offering the same reliable, airtight seal as their gray counterparts. These stoppers are also straight plug style and designed for use with 20mm flip-top, flip-off, or standard aluminum seals. The red coloring helps with easy identification and differentiation from other stoppers in your inventory.

Silicone Vial Stoppers

Our 20mm silicone vial stoppers are the premium choice for those who require superior quality and durability. Unlike butyl rubber stoppers, silicone stoppers offer enhanced resistance to humidity, water damage, and chemical exposure. Their solid, clear design provides a sterile, clean appearance, making them ideal for applications that demand a higher aesthetic standard.

Whether you need the reliable sealing capabilities of gray or red butyl rubber stoppers or the superior resistance of silicone stoppers, Med Lab Supply has you covered with top-quality products designed to meet your lab’s specific needs.
