Idex Biocompatible Inline Filters

Biocompatible Inline Filters

 

  • 0.5 μm and 2 μm versions available
  • Features 100% PEEK flow path

 

Upchurch Scientific A-430 and A-431 Inline Filters consist of a stainless steel body and two PEEK end fittings, one with a built-in 2 μm or 0.5 μm PEEK frit. Both filters are pressure rated to 6,000 psi (414 bar), with maximum recommended flow rates of 25 mL/min for the A-430 Filter and 10 mL/min for the A-431 Filter. And, you get the added benefit of biocompatibility since all wetted surfaces are PEEK. When you need to replace the frit, simply dispose of the end fitting that contains the frit and replace it with a new one. The end fittings have 10-32 female ports to connect 1/16” OD or smaller tubing using standard Fingertight fittings.

 

Application NOTE:

 

Increase the Life of Your Column

  • Why use a Precolumn Filter when there is a frit at the head of the column itself? Changing the column frit is extremely difficult to do without disturbing the column packing. A precolumn filter provides relatively inexpensive insurance against column damage, and changing its frit is easy. A Precolumn Filter placed between the sample injection valve and the HPLC column protects the column from particles originating in the sample and from pump and valve seal wear.

 

NOTE:

 

What’s the Difference Between Precolumn & Inline Filters?

  • You may have noticed that the bodies of Precolumn and Inline Filters look similar, and as such, you may have wondered what the differences are. Because Precolumn Filters, by definition, are typically placed in a volume sensitive area immediately preceding the column, these filters usually feature smaller thru-holes, smaller frit diameters, and lower overall internal volumes. In contrast, Inline Filters are often placed where the internal volume is not as critical and where longer life and less fluid restriction is more important.
