PEEK Zero Dead Volume unions: Zero Dead Volume (ZDV) unions come complete with two F-300 fingertight fittings for ¹/₁₆" Ext.Ø tubing and are pressure rated to 5000 psi (344 bar).

PEEK NanoTight™ union: The unions come complete with two F-331N fingertight fittings and are pressure rated to 5000 psi  (344 bar). The internal design of the unions reduces tubing misalignment. When using ¹/₁₆" Ext.Ø tubing sleeves to connect capillary tubing, the webbed thru-hole minimises breaking of fused silica while adding only miniscule swept volume. The results are: Fewer blockages, fewer flow rate reductions and fewer back pressure problems.

PCTFE column coupler: These couplers will connect most columns with 10-32 internal threads to a pre-column filter or guard column with the same threads. They may also be used to join two columns in series.

The unions come complete with two F-331N fingertight fittings and are pressure rated to 5000 psi (344 bar). The internal design of the unions reduces tubing misalignment. When using 1/16" OD tubing sleeves to connect capillary tubing, the webbed thru-hole minimises breaking of fused silica while adding only miniscule swept volume. The results are:
