ColumnSaver Pre-Column Filters

.• Economical column protection
.• Protect columns from particulates
.• Compatible with all HPLC columns
.• Ultra-low dead volume

Placed immediately before the column, pre-column filters trap sample particulates and provide a convenient, lower cost solution than the use of guard cartridges (see p.26/27). However, for samples that may irreversibly adsorb onto the column, guard cartridges remain the preferred choice for maximum column protection.
The ColumnSaver pre-column filter is simply hand tightened into the column inlet (no tools are required), and is leak-proof to over 5000psi. Both 2µm and 0.5µm versions are available, for protection of 5µm and 3µm columns respectively.
ColumnSaver pre-column filters are universally compatible with all column manufacturers' end fittings, and may be used with either stainless steel or PEEK tubing and nuts (see Figure 4). It is recommended that pre-column filters are replaced when a 10-20% increase in back pressure is detected.
