DALON offers custom-engineered sintered plastic filters for passive liquid systems. Under ISO 9001:2015-certified processes, we provide:
Precise pore control and stable hydrophilic surface energy
OEM customization: cone angle, wall thickness, pore grade, bonding
Hydrophilic or hydrophobic variants for specific fluid behavior
Biocompatible, food-grade, or EO/gamma-sterilizable versions on request
Q1: What makes this cone hydrophilic?
Its surface is treated to attract and retain water, enabling smooth, self-starting fluid flow through capillary force.
Q2: What liquids can this filter handle?
It is suitable for aqueous-based liquids including diagnostic reagents, lab fluids, and water-based samples.
Q3: Can it be sterilized?
Yes. It supports ethylene oxide (EO) or gamma irradiation sterilization methods. Autoclaving is not recommended for PE.
Q4: Is it reusable?
Yes. It can be rinsed with water or cleaned using ultrasonic baths depending on contamination.
Q5: Can it be made in different sizes or pore ratings?
Absolutely. DALON supports full OEM customization of shape, pore size, cone geometry, and surface properties.
Q6: Which industries benefit from this filter?
Used in medical diagnostics, lab sample handling, fluid sensors, environmental testing, and point-of-care platforms.
The versatility of SINTERED PLASTIC FILTER CONE 3.8X29.5 20MICRON makes them ideal for various industrial applications. Key industries that benefit from these plastic filters include:
