How to Choose the Right Frit
Choosing the right frit depends on the application, particle size, solvent environment, pressure requirements, flow rate, compatibility needs, and whether the frit will be used in a standard laboratory workflow or an OEM assembly.
Material
Material selection should be based on the application, solvent conditions, compatibility requirements, and whether the frit will be used in a standard chromatography workflow, a bioinert application, or a custom OEM assembly. OPTI-FRIT sintered frits are available in 316L stainless steel and titanium. For a deeper comparison, read our guide to stainless steel vs titanium frits for HPLC, UHPLC, and LC/MS.
When corrosion resistance is a concern, titanium may be a better starting point depending on the solvent environment and application requirements. If you are unsure which material is appropriate, send us your application details, drawing, sample, or existing part number for review.
Porosity
Porosity should be selected based on the particles being retained, system pressure, flow rate, solvent environment, assembly geometry, and application requirements. Smaller pore sizes can provide finer particle retention, but may also increase flow restriction or backpressure. Larger pore sizes may reduce restriction, but may not provide the same level of fine-particle retention. For more detail, see our guide on how to choose the right HPLC frit porosity.
Diameter and Thickness
Frit diameter and thickness affect fit, mechanical support, pressure behavior, flow characteristics, and assembly compatibility. OPTI-FRITs can be customized to match application-specific requirements.
Testing Requirements
Depending on your application, testing may include flow, backpressure, bubble point, particle retention, mass spectrometry validation, and documentation certificates. If your system is experiencing pressure problems, read our troubleshooting guide on what causes HPLC frit clogging and high backpressure.
