PP Membrane Filter Holder
Description
Polypropylene (PP) membrane filter holder designed for routine laboratory filtration, sample preparation, and cost-efficient OEM applications.
This reusable filtration holder is widely used in laboratories and research workflows where aqueous solution filtration, sample clarification, and microbiological testing are required. It provides a stable and flexible platform for membrane-based filtration.
- Material: Polypropylene (PP)
- Reusable design for routine laboratory use
- Compatible with syringe and vacuum filtration systems
- Supports standard membrane filters (MCE, PES, PTFE, PVDF, Nylon, CA)
- Available in multiple diameters (13 mm / 25 mm / 50 mm)
- Suitable for OEM and bulk procurement supply
Why Choose PP Membrane Filter Holder
- Cost-efficient solution for routine laboratory filtration
- Suitable for aqueous and mild solvent applications
- Flexible membrane selection for different workflows
- Reusable design reduces consumable cost
- Compatible with standard laboratory filtration setups
Working Principle
The membrane is placed inside the holder and sealed using an O-ring system. Sample is introduced via syringe pressure or vacuum system. Particles and contaminants are retained on the membrane surface while filtrate passes through for analysis.
Product Structure
- PP housing body
- Membrane support screen
- Sealing O-ring (silicone / EPDM / FKM)
