Standard Precolumn Filters have 0.020” (0.50mm)
diameter thru-holes and 8° distribution cones for minimal band
spreading andmixing. They feature stainless steel bodies, and pressure
rated to 6,000 psi (414 bar) and both accept 1/16” OD tubing and
standard 10-32 threaded high pressure fttings.
With a 0.010” (0.25mm) diameter thru-hole, our A-318 Filter has one of
the lowest swept volumes (0.61µL*) of any analytical HPLC precolumn
flter available, ensuring maximum protection with very little band
broadening. Pressure rated to 6,000 psi (414 bar).

Inline Solvent Filters
Excellent for general purpose inline use
2 µm and 20 µm porosity frits available
Placed between the pump and sample injection valve, Inline Solvent
Filters trap particles released through normal piston seal wear. Without
an inline flter, particles can be fushed through your system’s tubing
to the sample injection valve, resulting in valve damage and further
system contamination.
These filters are pressure rated to 6,000 psi (414 bar) and use a
2 µm or 20 µm stainless steel frit. An 8° distribution cone helps
spread the fow of the mobile phase over the entire surface of the
frit, while the 0.050” (1.3 mm) diameter thru-hole allows virtually
unrestricted solvent fow rates.

Fittings
All flters on these two pages have 10-32 internal threads for 1/16” OD tubing,
conveniently allowing the use of Fingertight Fittings. Use any of the all-
polymer 10-32 Fingertight Fittings found on pages 11, 13 and 15 with these
flters. For the stainless steel flters, you may also use the 10-32 stainless steel
fttings on page 10.
Frits
Any of the polymer-ring encased frits from pages 167 – 171 with an overall
diameter of 0.247” to 0.254” can be used with the flters on this page and the
biocompatible precolumn flters.
