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.
