The 20 micron stainless steel suction filter is an important pre-filtration component in the solvent delivery process of liquid chromatography systems. Its uniformly distributed pores capture fine particles effectively, keeping solvents clean and reducing the risk of blockages in tubing and chromatographic columns. Constructed from stainless steel, it offers high mechanical strength and corrosion resistance, maintaining stable performance during long-term contact with a wide range of organic solvents.

In use, the filter is directly connected to the solvent bottle, allowing liquid to be evenly drawn in and filtered before entering the system. With its compact and durable design, it supports consistent fluid purity and lowers the chance of clogging, making it suitable for both routine analysis and demanding laboratory applications.

Direct Suction Optimized Flow Design
Specially designed suction interface allows solvents to enter evenly, working in concert with the microporous structure to provide efficient pre-filtration and stable continuous analysis.

System Compatibility Optimized Geometry
The filter fits a wide range of HPLC solvent bottles while maintaining consistent flow rates and minimizing fluid disturbance during analysis.

applications

Solvent Pre-Filtration to Protect Columns
The filter captures fine particles in HPLC solvents before they enter the system, preventing column blockage and enhancing analytical stability.

Stable Flow for Continuous Sample Analysis
Its direct suction design ensures uniform solvent intake, maintaining consistent flow rates during extended continuous analyses and minimizing disturbances that could affect results.

Compatibility with High-Polarity Organic Solvents
Constructed from SS316L stainless steel, the filter withstands solvents such as acetonitrile and methanol without metal leaching or contamination, even under strong polarity conditions.

Front-End Protection and Reduced Maintenance
The compact filter attaches directly to solvent bottles, providing upstream system protection and reducing maintenance frequency for tubing and pumps.

Applicable for Routine and High-Precision Analyses
With 20-micron pore precision and integrally sintered construction, the filter meets requirements for both standard laboratory work and demanding high-precision HPLC applications.
