Which component is used to add or remove material from the isolator without breaking containment?

• A. Transfer sleeve
• B. Supply cylinder
• C. Laminar flow tube
• D. Trexler tube

Answer: (A)

Transferring materials into and out of an isolator must be done without breaching the contained environment. The transfer sleeve provides a sealed, pass-through pathway that allows you to move items in or out while the barrier remains intact. It’s designed to maintain the isolator’s pressure and containment, so contaminants can’t escape and the interior stays controlled. This makes it the best choice for adding or removing material without breaking containment.

The other options don’t fulfill this transfer-without-breach role. A supply cylinder is about providing gas or pressure, not moving materials through the barrier. A laminar flow tube directs airflow to maintain a clean environment but doesn’t enable barrier-crossing transfers. A Trexler tube is a pass-through device, but the transfer sleeve is the standard component used to perform material exchange without compromising containment.
