Tosoh Bioscience offers a limited line of replacement parts for its columns and guard columns. With the introduction of TSK-GEL BioAssist series, the TSK-GEL column line consists of stainless steel, glass and PEEK columns.

The tubing, fittings and frits in the stainless steel TSK-GEL columns are manufactured from 316-grade stainless steel. The top and bottom end-fittings are engraved with the pore size of the frit. If the top frit plugs, the entire end-fitting can be removed and replaced. Order the appropriate replacement fitting according to the ID of the column. Stainless steel end-fittings will connect to the 10-32 PEEK or stainless steel nuts and ferrules on a standard HPLC system.

The end-fittings on the glass columns contain Pyrex^® frits with a nominal 10μm pore size. The materials in the glass column fittings that come into contact with the sample and the mobile phase are chlorotrifluoroethylene and tetrafluoroethylene. The end-fittings will connect to 1/4-28 and also to M6 nuts and ferrules.

Tosoh Bioscience recommends that each column be protected by a guard column and filter. Guard columns are listed with corresponding columns in each section of this website. We recommend installing a pre-column filter in front of the (guard) column to avoid clogging the top frit, particularly when working with columns that contain smaller than 5μm particles. In addition, when suspecting debris from the breakdown of pump seals, we have found it beneficial to use a pre-injector membrane filter to prevent any particulates from reaching the injector and/or (guard) column.
