High capacity TwistTop vials combine all the outstanding features needed in a screw-cap vial for collection, processing, centrifugation, transportation and storage of critical biological samples. Two ful turns of TwistTop vial's precision molded cap are all that is needed to create a safe and reliable cap-to-vial seal. A flexible ethylene/propylene O-ring secures the cap-to-vial seal by compressing uniformly against a bevelded seat. In addition vertical ribbing on the deep-skirted cap minimizes potential contamination during aseptic handling procedures.
