Abstract

A probe assembly for a closed transfer system is provided. The probe assembly includes a base having a base air inlet, a probe having a base end and a probe end, at least one primary valve positioned at the probe tip, and at least one secondary valve. The probe defines a hollow air channel extending from the base end to the probe end including a probe tip, the base end being coupled to the base such that the hollow air channel is in fluid communication with the base air inlet and the probe tip. The at least one secondary valve is positioned at the base air inlet and configured to selectively allow air into the hollow air channel.
