High Pressure Filters - PEEK Precolumn Filter Kit

 

  • 100% biocompatible

  • Minimal hold-up volume

  • Replaceable metal-free polyetheylene frits and biocompatible titanium frits encased in PEEK

  • Different porosities

  • 0.25/0.40 mm bore

  • 10-32 threads

  • Pressure rating <350 bar (< 5000 psi)

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

 

Peek Precolumn Filter Kit
 

The precolumn filter kit has a standard 10-32 fitting and fits direct to most column types without introducing additional dead volume. The filter kit protects expensive columns against fine particles, which may otherwise accumulate on the column frit and lead to split peaks and high backpressure.

* The internal volume is the hold-up volume between the end of the connecting tube and the filter 10-32 connector outlet, including the frit volume.

** Flowrate measured with methanol/water (1:1), ultrasonic degassed, helium sparging to prevent regassing.
