A ___________ is a flexible plastic tube used to add material to or remove material from the isolator.

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

Answer: (A)

The material passes through an isolator using a transfer sleeve, which is a flexible plastic conduit designed to extend through the isolator wall. This sleeve allows you to add or remove items without breaking the sterile or contained environment inside the isolator. You slide containers or materials through the sleeve from the outside and retrieve them on the inside (or vice versa) while the barrier remains intact, helping maintain asepsis and containment. Other options don’t fit because they aren’t flexible plastic sleeves used for passing materials. A supply cylinder is for delivering gases or liquids, not for transferring items through an isolator. A laminar flow tube relates to airflow and filtration, not material transfer. A Trexler tube may be used in transfer contexts but is typically not the flexible sleeve described here.
