The IDEX Semi-Prep Frit, 20 µm, 0.188 in Disc, 0.254 in Ring (A-122; Cole-Parmer item 02010-59) is a replaceable stainless steel filtration element for compatible semi-preparative chromatography filter assemblies. It combines uniform 20 µm porosity with a PCTFE sealing ring and a verified frit volume of 9.7 µL.
Key Features
- Uniform 20 µm filtration porosity, helping prevent damaging particulate matter from passing into downstream system components
- Stainless steel frit construction, providing a durable filtration surface for compatible chromatography applications
- Precisely sized 0.188 in disc diameter, equivalent to approximately 4.8 mm
- Defined 0.074 in disc thickness, equivalent to approximately 1.9 mm
- Chemically resistant PCTFE sealing ring, supporting a secure seal within a compatible filter housing
- Compact 0.254 in ring diameter, equivalent to approximately 6.5 mm
- Low 9.7 µL frit volume, limiting the additional internal volume introduced by the filtration element
- Replaceable filtration format, allowing a contaminated frit to be renewed without repeated cleaning
Benefits
- Helps protect chromatography equipment from particulate contamination and associated flow restrictions.
- Supports consistent filtration performance through a uniform, defined pore size.
- Reduces maintenance time by replacing contaminated frits rather than cleaning embedded debris from used components.
- Provides a cost-effective way to renew the filtration element without replacing the complete filter assembly.
