Patent ID: 7114531

Claim:
A system for purging high purity interfaces comprising: a first purging manifold comprising, a first diaphragm valve having a first side and a second side, a first conduit extending from the first side, a first low dead space fitting, connecting the first conduit to first adapter manifold extending from a first high purity chemical container, a second diaphragm valve having a third side and a fourth side, a second conduit connecting the third side to the first side, a third conduit extending from the fourth side, a second low dead space fitting, connecting the third conduit to a first source, wherein the first source is a source of vent or a source of vacuum, a fourth conduit extending from the second side, a third low dead fitting, connecting the fourth conduit to a second source, wherein the second source is a process tool, a second high purity chemical container, a source of purge gas, or a source of vacuum; and a second purging manifold, comprising, a fifth conduit having a first end and a second end, a fourth low dead space fitting, connecting the first end to a second adapter manifold extending from the first high purity chemical container, and a fifth low dead space fitting, connecting the second end to a third source, wherein the third source is a source of push gas, a source of purge gas, or a source of vacuum.
