Is there an easy way to filter my solvent path while using capillary or fused silica tubing?

IDEX Health & Science has created the Precolumn MicroFilter, the Inline MicroFilter and the Mini MicroFilter specifically for this purpose. Most of our MicroFilters utilize our MicroTight tubing sleeves along with two Micro-Fingertight fittings to accommodate most sizes of capillary or fused silica tubing. Two versions of our mini MicroFilter directly connect 360-380µm OD capillary tubing without the use of tubing sleeves.

The Precolumn and Inline MicroFilters retain particles larger than 0.5µm flowing through capillary tubing, with the use of a built-in 0.5µm PEEK frit. Capable of holding 5,000 psi of continuous pressure, these filters can be used in either high-pressure or low-pressure environments. The Precolumn MicroFilter has 10-32 male threads and is designed for direct-connecting into your microbore or other column. The Inline MicroFilter utilizes 6-32 threads for use with our Micro Fingertight fittings.

The Mini MicroFilter contains a thin stainless steel microscreen that offers a dramatic reduction in theoretical void volume, at only .085 microliters (includes frit volume). This filter is available with 1- and 2-micron porosity replaceable filter capsules, and employs a combination of a female nut and a specifically designed ferrule.
