The IDEX Inlet Solvent Filter, 20 µm, 3/16 in OD (A-231A; Cole-Parmer 42711-13) is an analytical solvent filter designed for installation on 3/16-inch outside-diameter pump inlet tubing. Its 20 µm stainless steel filtration element helps prevent particulate matter from entering the solvent flow path, with a maximum recommended flow rate of 100 mL/min.
Key Features
- 20 µm solvent filtration, retaining particulate matter larger than the filter porosity before it enters the pump system
- Designed for 3/16-inch OD tubing, matching the specified solvent inlet tubing size for this configuration
- Maximum flow rate of 100 mL/min, supporting analytical and higher-flow solvent delivery applications
- Stainless steel and PCTFE construction, combining a stainless steel filter with a polymer flangeless connection
- Low-pressure flangeless fitting, providing a direct connection to compatible solvent inlet tubing
- Supplied with connection components, including the P-132 nut and P-133 ferrule for 3/16-inch OD tubing
- Disposable filter design, allowing routine replacement as part of preventive system maintenance
- Tool-free replacement, simplifying regular filter changes without specialised equipment
Note: Confirm the chemical compatibility of the stainless steel, PCTFE and fitting materials with the intended mobile phase before use.
Benefits
- Helps protect pumps and downstream fluidic components from damaging particulate contamination.
- Reduces the risk of restricted solvent flow and pump cavitation caused by contaminated mobile phases.
- Simplifies preventive maintenance through disposable, tool-free filter replacement.
- Supports straightforward installation with the required 3/16-inch tubing fittings included.
- Provides a defined 100 mL/min maximum flow rating for system and method planning.
Why Choose the IDEX Inlet Solvent Filter, 20 µm, 3/16 in OD (A-231A; 42711-13)?
The IDEX A-231A provides a compact and replaceable filtration point between the solvent reservoir and pump, helping prevent damaging particles from entering the chromatography system. Its 20 µm stainless steel filter, 3/16-inch flangeless connection and 100 mL/min maximum flow suit compatible analytical solvent-delivery configurations. John Morris Group can assist with filter selection and compatible tubing and fitting requirements.
