Designed for HPLC columns with 10-32 mm threads to connect HPLC columns to other HPLC columns including guard columns. Columns can be easily placed into series for two dimensional HPLC.

These column couplers are also known as column connectors and are compatible with all Cogent HPLC columns and most other HPLC column brands on the market. The connecting tubing is the ARE brand of Ultra-T that has very tight tolerance for high internal concentricity which is needed for optimal HPLC flow. The tubing can be moved side to side in the coupler which allows for column pilot depth adjustment making it almost universal.
