Valco® Pre-Column Filter

In-line installation. Efficient, low dead volume filters protect your columns from particles without reducing column performance. The replaceable 1/8in. frit has 0.5 μm pores to protect 3 μm or 5 μm column packings, the replaceable screen has 2 μm pores. Choose the frit filter for higher filtration capacity (most applications) or the screen filter for less dead volume (e.g., with microbore columns). Use with 1/16in. O.D. tubing; 1/16in. fittings included.

Frits and screens should not be interchanged inn these filters.
