Draeger Tubes n-Butanol 10/a (P/N: 81 01 861)

Production Batches affected: ARLF-0091 / ARLM-0111 and ARMD-0121 / ARMM-0131

August 10, 2021

To our valued customers and partners,

During the course of routine product surveillance activities it has come to our attention that the

indicator layer of Dräger Tubes n-butanol 10/a (81 01 861) of the affected batches may show a greenish coloring even in unused tubes, rather than the yellowish coloring described in

the Instructions for Use.

This will make it difficult to distinguish the greenish discoloration that indicates the presence of n-Butanol.

Draeger is requesting customers with the affected batches to discontinue use of the tubes and dispose them in accordance with local regulations, or arrange to return them to Draeger by contacting Draeger Customer Service.

Contact Draeger Customer Service for instructions on receiving a like number of replacement tubes free of charge. Estimated availability is 11/30/2021.

We apologize for any inconvenience caused and thank you in advance for your understanding.
