• Autoclavable for sterile workflows
• OEM customization and bulk supply available

Why Choose a Stainless Steel Disc Filter System

• Higher throughput compared to vacuum and syringe filtration systems
• Scalable from laboratory testing to pilot-scale processing
• Compatible with multiple filtration media types
• Reusable structure reduces long-term equipment cost
• Suitable for method development and process optimization

What Is a Stainless Steel Disc Filter Holder

A stainless steel disc filter holder is a reusable pressure filtration device designed to support interchangeable filter media including cloth, paper, and membranes.

It functions as a structural filtration system rather than a consumable, allowing users to adjust filtration performance by selecting appropriate filter media without changing the hardware.

This makes it suitable for laboratory filtration, pilot-scale batch processing, and multi-stage filtration workflows.

Filtration Principle

Pressure differential drives filtration performance:

Liquid passes through the selected filter media under controlled pressure. Filtration efficiency is determined by the media:

• Filter cloth – coarse particle separation
• Filter paper – medium and fine clarification
• Membrane filters – precision filtration

The stainless steel holder provides mechanical support and sealing, not filtration accuracy.

Engineering Structure

• Stainless steel housing (304 or 316L)
• Perforated support plate for uniform flow distribution
• Chemically resistant silicone sealing gasket
• Mechanical clamping system
• Inlet and outlet flow ports

The design ensures uniform pressure distribution, reduced leakage risk, and stable operation under repeated use and sterilization.

Technical Specifications

System Selection Guide

1. Select Diameter Based on Batch Volume

• 100 mm – laboratory testing (≤10 L)
• 150–200 mm – routine filtration (10–50 L)
• 300–400 mm – pilot-scale processing (≥50 L)

2. Select Filter Media Based on Application

• Coarse separation → Filter cloth
• Standard clarification → Filter paper
• Fine filtration → Membrane filters

3. Select Material Based on Chemical Compatibility

• 304 – general laboratory and food applications
• 316L – corrosive chemicals and pharmaceutical use

Typical Applications

• Laboratory sample clarification and preparation
• Pharmaceutical buffer and intermediate filtration
• Food and beverage quality control filtration
• Chemical process development and separation
• Pilot-scale batch filtration systems

Disc Filter Holder vs Membrane Filter Holder

• Larger filtration area and higher throughput
• Supports cloth, paper, and membrane media
• Pressure-driven vs syringe/vacuum operation

Disc Filter Holder vs Vacuum Filtration System

• Higher throughput under pressure conditions
• Better performance with viscous liquids
• More stable mechanical structure

Disc Filter Holder vs Filter Press

• Compact single-plate design
• Faster media replacement
• Simpler operation for lab and pilot use

Role in Filtration Workflow

• Coarse filtration (cloth)
• Intermediate clarification (paper)
• Fine filtration (membrane)
• Downstream analytical processing

This makes it a core structural component in multi-stage filtration workflows.

Compatible Filtration Consumables

• Laboratory Filter Papers
• Membrane Filter Media

Frequently Asked Questions

Is this a consumable filter?

No. It is a reusable filtration device used with interchangeable filter media.

What determines filtration accuracy?

Filtration precision depends on the selected filter media, not the stainless steel holder.

What media are compatible?

Filter cloth, filter paper, and membrane filters of matching diameter.

Can it be used with corrosive chemicals?

Yes, 316L stainless steel is suitable for corrosive and pharmaceutical applications.

Is it autoclavable?

Yes, the system can be sterilized at 121°C without filter media.
