Title: Seal for permitting transfer of tape from one pressure region to a region of substantially different pressure

Abstract

A seal is provided for allowing a thin flexible tape to be pulled from a high vacuum region (less than 10.sup.-.sup.6 torr) into atmospheric pressure. The tape first passes through a slit in an elastomer and thence through a pool of vacuum pump fluid into a differentially pumped volume. A second slit in an elastomer is the final seal element prior to exit of the tape to atmospheric pressure. The vacuum seal is utilized in a system for the rapid removal of samples, implanted in the surface of the tape, from a vacuum system to atmospheric pressure.
