    • Q:

      If I need to order this, what will be the cost of the product? Is it $89 for just 1 order (all I need is one package) or do I have to pay $1780 for 1 order(i.e. unnecessarily purchasing the whole case of 20 packages)?

        We sell this in a pack of 15, 500 mm long, segments. You do not need to purchase the entire case of 20 of these packs.

        CryoFlex tubing is a heat shrink tubing, not a glue type. Please contact directly for further assistance. Contact information may be found under the "contact/about us" tab.

    • Q:

      How do we seal the tube? Is there any equip. needed? I cannot think that the tube is sealed by itself.

        The after the vials are positioned in the CryoFlex tubing, the tubing is gently heated with a heat gun (preferably with a heat-shrink tubing attachment). The heated ends can then be crimped, squeezed or even melted closed. To remove the vial, carefully cut around the cap seal .

    Comments about CryoFlex<tm> Tubing, 15/pack:

    The tubing was easy to use. The only problem was getting it to fit into our 81-slot freezer boxes when the cryotube was inserted.
