PCTFE Chromatography Column Frit Disc OEM Manufacturer

Lab Liquid Chromatography Column Hardware Filters
Changing HPLC column frit can withstand pressure up to 600.

uHPLCs® columns feature innovative particle technology:
*Enables faster and more efficient HPLC separations.

Material options for HPLC frit:
* PCTFE Circle
* Stainless steel sintered metal

Selection criteria for HPLC column frits:

* 0.2 μm pore size frit is used to retain packing prepared from 3 μm particles.

* 2 μm pore size frit is used to retain larger particles. 

* 0.2 – 20μ pore size option

* Ultrasonically cleanable.

* Requires special tools for mounting on both ends of the column.

Features and Applications:

uHPLCs’ Peek HPLC Frits Manufacturing Details:

  • We produce HPLC frits from chromatographic-grade 316 stainless steel.
  • We provide a variety of sizes to accommodate diverse column and pore sizes.
  • Our frits serve the dual purpose:
    • Protection of HPLC columns against particulate contamination.
    • Uniform distribution of dissolved samples, ensuring optimal column performance.

Choosing the Right Frit:

  • Ensure the frit’s pore size is compatible with the particle size of the column packing.
  • If the packing particle size is smaller than the frit’s pore size, there’s a risk of the frit getting clogged by the packing.

Replacement Frit Options:

  • Available in both PTFE and PE.
  • Come in a range of pore sizes to suit specific requirements.
  • When selecting a frit, it’s essential to match the column’s inner diameter (ID) for a precise fit.

Application Objectives:

  • Retain column packing effectively.
  • Ensure uniform distribution of the sample into the column.
  • Facilitate consistent sample flow into the column.
  • Meet specific customer flow dimension requirements.
  • Must be resilient, enduring pressures exceeding 6000 psi and highly corrosive conditions.
  • Minimize dead volume to enhance peak symmetry.
