OPTI-GUARD® 3mm Guard Column

The OPTI-GUARD 3 mm maintains the tool free connectivity of the OPTI-GUARD 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 providing vital protection from dirty samples and strongly retained contaminants. An auto adjusting stem conforms perfectly to any tube stop depth resulting in a perfect zero-volume connection.
Note: cartridges not included with holder.
