Optimize Opti-Guard® 3mm Guard Columns

Our OPTI-GUARD® 3.0mm guard columns maintain the tool-free connectivity of our 1.0mm products, but incorporates a cartridge-based format to allow for a larger bed with more capacity, offering alternative HPLC analysis solutions. The two-part holder is designed for use with any analytical column to provide vital protection from dirty samples and strongly retained contaminants.

Our OPTI-GUARD® analytical columns set the standard for extremely low impact, easy to use pre-column protection. Other options are available with alternative IDs(4.6mm, 3.0mm, and 2.1mm IDs).

Packing material/phase options available for this product include Cyano (CN), C4, Silica, Amino (NH2), C8 and C18.

Our patented floating stem design automatically adjusts to any manufacturers tube stop depth for a zero-dead-volume connection with every use. The best part? Its no larger than a standard fitting. Connecting with OPTI-GUARD® Guard Columns requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD® line so popular for HPLC analysis.
