Wheaton Straight Plug Rubber Stoppers

The Wheaton straight plug stopper design provides maximum sealing for vials and small lab sample bottles (e.g. serum vials & serum bottles) with straight-wall glass finish. The straight-wall interior finish is typically found in vials from European manufacturers. This style is not recommended for vials or serum bottles with a blowback feature. Select from straight plug stoppers made from butyl rubber, butyl-isoprene blended rubber, natural latex rubber, silicone or Viton® to fit your specific application.
