l Protects Your Columns

One of the major factors contributing to the short life of HPLC columns is particles being deposited on the frit and top of the column. These filters are designed for placement between the sample injection valve and the HPLC column. The filter protects the column from particles originating in the mobile phase, pump seal wear, sample injection valve wear, or in the sample.

Models A-315 & A-316 precolumn filters have .020" diameter thru-holes and 8° distribution cones for low band spreading and mixing.

Model A-318 has a .010" diameter thru hole and a removable stainless steel ring that fits around the frit, making the frit easy to remove and replace.Use this filter when you are concerned about the maximum resolution and for microbore work.

A 0.5mm or 2mm frit is available to stop particles before they reach the column. The 0.5mm frit will stop bacteria and smaller wear particles. The replaceable frits are stainless steel with a PEEK ring. The inlet and outlet connections are compatible with Upchurch, Swagelok, or Parker. All materials are type 316 stainless steel and KEL-F.

Inline Solvent Filter

l Protects Injector
l Easy to replace Frits

Placed between the pump and sample injection valve, our Inline Solvent Filter traps particles released through normal piston seal wear. Without an inline filter, these particles can be flushed through the capillary tubing to the sample injection valve, resulting in valve damage and further system contamination. This filter uses a 2 mm stainless steel frit with a PEEK ring to control contaminates before they reach the valve. An 8° distribution cone spreads the flow of the mobile phase over the entire surface of the .094" diameter x .062" thick frit, while .050" diameter thru holes provide good solvent flow. The inlet and outlet connections are compatible with Upchurch, Swagelok, or Parker.

All materials are type 316 stainless steel and PEEK.

Titanium Tubing

In certain high-pressure applications, stainless steel must be avoided and titanium tubing is an excellent alternative. Our titanium tubing is carefully cut to ensure a square, burr-free end. Since titanium is brittle, care should be used in bending or tightening titanium tubing. In addition, it is not recommended for use with strong acid because of potential cracking.
