The EXP® Analytical Column Holders are available in two formats: In-Line and Direct Connect, allowin…

OPTI-GUARD® 1mm Guard Columns set the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD® requ…

The OPTI-PAK Trap Columns unique hardware design integrates a PEEK holder with an auto-adjusting stem which provides a fluid interface with any 10-32 standard injector port, and guarantees a zero-dead-volume connection despite variances in tube stop depth. A proprietary method of frit placement allows the packed stem to be positioned directly into the flow path, which eliminates all excess swept volume. Less swept volume trans…
