Finger tight to 6000 psi (414 bar) without wrenches or other tools
Lower dead volume than conventional filters with holders
Universal connection compatible with all column manufacturers' fittings
Compatibility with stainless steel or PEEK™ tubing
The ColumnSaver precolumn filters offer all the protection of conventional precolumn filters at 1/3 of the cost. With its convenient direct connect design, changeover time is measured in seconds and no tools or wrenches are needed. The ColumnSaver PEEK body contains a HiFlo™ stainless steel or titanium filter element and is designed for maximum filtration of particulate matter with minimal dead volume or backpressure.
The ColumnSaver can also be used as a convenient, fingertight inline filter when used with a 1/16" union. As soon as an increase in backpressure is detected, simply remove and dispose of the ColumnSaver unit and replace it with a new one. The direct-connect design is compatible with 1/16" 10-32 internal fitting ports featured on many standard, high pressure stainless steel unions.
