HPLC Column Hardware

Column Coupler

The patented Column Coupler was developed for the demanding constraints of high efficiency HPLC columns.The Column Coupler permits the quick and easy connection of two analytical HPLC columns in series, or direct connection between a Valco injection valve and an analytical column. Seals are rated to 5,000psi.

The unit is a precision-machined, double-ended PEEK connector with 10-32 threads and a non-wetted Delrin^® knurled body. The inert composition and the large knurled handle allow easy, fingertight connections and leakproof seal to 5,000psi. The 0.010" through-hole minimizes extra column volume effects and is compatible with the demanding constraints imposed with use of 3µm packing and microbore HPLC. These couplers are not capable of universal applications since the tip sizes are fixed.

Guard Cartridge Holders

The Universal Guard Cartridge Holder was designed for use with the Transgenomic 4.0mm x 20mm guard cartridges. The PEEK IC Sep Holder was designed for use with the 3.0mm x10mm guard cartridges.
