OPTI-GUARD® 3mm Guard Columns


Sorry but this item is currently unavailable.



The OPTI-GUARD® 3 mm maintains the tool-free connectivity of the 1 mm, but incorporates a cartridge based format to allow for a larger bed with more capacity. The two-part holder is designed for use with any analytical column to provide vital protection from dirty samples and strongly retained contaminants. An auto-adjusting stem conforms to any tube stop depth for a perfect zero-dead-volume connection. Connecting the OPTI-GUARD® requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD® line so popular.
