In-line HPLC/UHPLC Precolumn Filters provide economical protection from the harmful effects of sample and mobile phase particulates on modern HPLC and UHPLC columns.  The PrimeLine precolumn filter was engineered specifically for use in high throughput and routine HPLC separations where mobile phase and sample contamination cause a decrease in column performance or premature column failure.  The low swept volume of the PrimeLine filter maintains the efficiency of high performance columns assuring a negligible loss of critical resolution.  With its simple design, the PrimeLine filter installs in any analytical column in seconds and is leak tight to 15,000 PSI.  Simply finger tighten initially, then wrench tighten an additional 1/4 - 1/2 turn.  

We offer the replacement filters.
