Stainless Steel frits
Replacement Stainless Steel Filter Discs
Chrom Tech offers analytical-scale 316 stainless steel frits engineered for reliable particulate retention and long service life in HPLC and UHPLC systems. Available in the two most common filtration ratings — 0.5 µm and 2 µm — these replacement filter discs provide consistent performance across a wide range of analytical applications.
Each stainless steel frit is supplied with a durable PCTFE or PEEK polymer sealing ring, ensuring proper sealing and stable installation within compatible filter assemblies. For higher flow rate requirements, select frits with larger diameter faces and/or higher porosity. For applications sensitive to extra flow path volume, smaller diameter faces and finer porosity options help minimize swept volume while maintaining effective filtration.
Designed for exceptional uniform porosity and mechanical strength, these stainless steel filter discs support dependable chromatography by protecting columns and downstream components from particulate contamination while preserving system efficiency.
