MST™ brand caps

  • MST flat caps
  • MST H caps
  • MST tether caps

    We have three versions of polyethylene caps for you to choose from: flat top, recessed and tethered. All of our polyethelyene screw caps feature a molded-in sealing ring for a rim-seal that provides a leakproof closure without the use of a silicone gasket. Evergreen pioneered rim-seal caps in 1975. We have found that a properly designed rim-sealing cap is extremely effective in sealing small vials with diameter openings of less than 40 mm. Like our Cryosure® vials, our new MST™ tubes’ sealing efficacy is no less than 99.9%. All three types of caps are available in natural, green, red, blue, yellow, orange, lavender and white colors.
