Re-Seal Tubes

The Re-Seal tube system was developed and patented to provide a reusable mechanical seal for the popular Quick-Seal tube configuration. Note that unused Quick-Seal tubes from Beckman may be employed as reusable tubes in the Re-Seal system. Re-Seal tubes with crown assemblies can be used in a variety of Beckman vertical and fixed-angle rotors. With the Re-Seal system the use of heat and experisive heat sealing stations is eliminated-the seal is made with a simple hex key wrench. Re-Seal Polyclear and autoclavable polyallomer tubes provide choices in chemical properties and clarity and can be punctured and sliced.

How to Use:

After the Re-Seal tube is filled a crown is placed on the stem of the tube, a plug is screwed into the stem and hand-tightened with the wrench. As the tube and crown are hand-held, no vise is required. As the plug is screwed in, it forms a thread in the stem of the tube providing a reliable compression seal. After centrifugation, the plug is unscrewed. A fraction recovery device can be screwed directly onto the crown and small bore tubing extended through the stem of the tube.

Aluminum crowns, stainless steel plugs and polyallomer tubes can be autoclaved. Polyclear and polyallomer tubes and all crown components can be sterilized with ethylene oxide gas or aqueous of 70% ethanol, 70% isopropanol or 10% hydrogen peroxide.
