These solid silicone vial stoppers are sure to fill many needs due to its superior quality compared to regular butyl rubber stoppers.  Silicone is naturally resistant to humidty, and contamination via humidity or water damage. Additionally when compared to Butyl Rubber, Silicone Gel Stoppers are more chemical, acid, and temperature resistant than traditional butyl stoppers. These silicone gel stoppers have a clean, transparent, and sterile look for an aesthetically neater product versus solid stoppers.

20mm Silicone stoppers used to seal 20 mm serum vials in combination with 20 mm flip top, flip off, and standard aluminum seals. Provides an airtight seal. "20mm Silica Stoppers CAN NOT be used with the 2mL vials."

  1. Leak review by John on 12/21/2017

    I thought these would be better than the cheaper ones but they leak when you put the needle in. Buy the cheaper ones and save yourself money.
