WHEATON® Rubber Stopper, Straight Plug, 20 mm, Gray Chlorobutyl-Isoprene Blend, 40 Durometer

  • Variety of styles, sizes and rubber formulations
  • Manufactured from the highest quality raw materials
  • Components manufactured to yield exceptional dimensional stability
  • Straight plug stoppers provide maximum sealing for vials with straight-wall glass finish. This style is not recommended for vials with a blow-back feature.
  • Snap-on style provides maximum sealing for vials with a blow-back glass finish, which is a small ridge on the interior of the vial's neck. The snap-on stopper locks into the blow-back ridge, providing a tight seal and keeping the stopper from backing out.
  • Sleeve style stoppers feature a fold-over skirt for sealing in serum finish vials without a crimp closure. They can be used as an injection site for multiple dose entry.
  • 2-leg and 3-leg stoppers are used for lyophillization applications.
  • Autoclavable
