An autoclavable electronic interface for germfree isolators.

An electronic interface was designed and fabricated for use with germfree isolators. It allows a variety of sensors or electrical instruments inside an isolator to be readily connected to monitoring or activating devices on the outside of an isolator. It was built into a 25 cm diameter cylinder whose open ends were loosely covered by an inner and outer connector panel. These two panels were wired together through an airtight dividing wall placed transversely across the middle of the cylinder. The interface was mounted in an entry port of a stainless steel isolator and steam sterilized with the isolator. It has proven to be a useful, contamination-free, durable device.
