Stainless Steel Precolumn Filter - Ultra-High Pressure

VICI Jour's stainless steel precolumn filter is based on our well-known in-line filter. Its unique design reduces the number of connections compared to a standard in-line filter, which increases stability and reduces the potential of leakage.

Small-bore sizes (0.15 mm in the nut/body and 0.13 mm in the tubing) guarantee a very small hold-up volume—virtually zero. With minimal dead volume, these precolumn filters are available in four frit porosities.

• UHPLC (up to 450 bar / 6500 psi for 0.2 micron porosity)
• Minimized hold-up volume
• Four porosity options: 0.2 µm, 0.5 µm, 2 µm, or 5 µm.
• Fewer connections compared to in-line filters reduce the potential for leaks
• Works with 1/16" column connections from all manufacturers

Materials: 

• Bore sizes: 0.13 mm bore for tubing, 0.15 mm for nut/body
• 10-32: female for inlet, male for outlet
• Pressure rating with ZN1 nut and ZF1S6 ferrule: 1375 bar ( 20,000 psi)

TECH TIP

We recommend 2 µm frits for columns with 5 µm or larger particles, and 0.5 µm frits for smaller particles.
