Column Couplers

  • Low swept-volume connections


These universal column couplers permit a low swept-volume connection, with minimal loss in column efficiency. These couplers will connect most columns with 10-32 internal threads to a precolumn filter or guard column with the same threads. They may also be used to join two columns in series.

Upchurch Scientific manufactures two styles of column couplers. One version is a single piece that makes coupling columns to guard columns or precolumn filters easy and hassle-free. We also offer our traditional couplers that consist of two Fingertight fittings and a short length of 1/16” OD tubing—an excellent option for reducing overall flow path volume while coupling two devices together reliably.
