Product Description
Get balanced venting and positioning during freeze drying. A three-leg stopper design sits evenly on the vial neck, helping maintain consistent vapor paths through the cycle and seating cleanly when the shelves press stoppers closed. They are intended for production and pilot lyophilization runs.
