SINTERED PLASTIC FILTER CONE 3.8X29.5 20MICRON

Hydrophilic Plastic Filter Cone – 3.8×29.5 mm, 20µm for Passive Liquid Transfer

DALON’s hydrophilic-treated sintered PE cone filter is purpose-built for capillary-driven liquid movement, sample filtration, and moisture-regulated applications. With 20µm nominal pore size and a slim conical shape (3.8 mm diameter × 29.5 mm length), it enables smooth, pressure-free aqueous flow—ideal for use in diagnostic devices, lab cartridges, and fluid sensors.

Key Features

• Filtration rating: 20 microns (nominal)

• Dimensions: 3.8 mm base diameter × 29.5 mm cone length

• Material: Sintered polyethylene (PE), hydrophilic surface treated

• Promotes capillary action and uniform saturation

• Allows liquid to wick through without external pressure

• Non-toxic, moisture-activated, and reusable

Typical Applications

• Pre-filtration and wicking in diagnostic test strips

• Capillary flow regulation in microfluidic systems

• Vent filters with water vapor activation

• Sample transfer in point-of-care analyzers

• Sensor hydration or chamber humidification

FAQ – Frequently Asked Questions

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.
