Syringe Filter

Reusable Filter Holder

Reusable filter holders are designed for membrane filters ranging from 13 mm to 300 mm in diameter. These holders provide a durable, reusable platform for both laboratory and industrial filtration applications, reducing consumable costs over time while maintaining consistent performance across sample types.

Reusable design reduces long-term consumable costs compared to single-use syringe filters
Multiple connection types (luer slip, luer lock, hosebarb) allow integration with syringes, tubing, and manifolds
Single and double-layer configurations support high-flow or high-load filtration tasks
Suitable for both routine lab use and industrial-scale filtration systems

Where It Is Used

Applications And Buyers

Application Scenarios

Filtering high-volume samples in pharmaceutical QC where repeated filtration is required
Connecting membrane filters to tubing lines in industrial process filtration setups
Using in batch processing where multiple samples are filtered through the same filter holder
Supporting large-diameter filters (150 mm and 300 mm) in environmental or food safety testing
Integrating with automated systems using hosebarb fittings for continuous flow applications

Who It Is For

Pharmaceutical and biotech labs running high sample volumes with repeated filtration needs
Environmental testing labs handling large water or soil extract volumes
Food and beverage labs requiring consistent filtration across multiple batches
Industrial filtration operators using large membrane filters in continuous processing
Lab distributors sourcing reusable filtration components for resale or OEM packaging

Problems It Solves

High consumable cost from using single-use syringe filters in high-volume workflows
Inconsistent performance when switching between different filter geometries or materials
Difficulty in connecting membrane filters to tubing systems without proper fittings
Filter holder failure under pressure due to weak seals or material degradation
Lack of standardization in filter holder design across different membrane sizes and applications

Comparison

Compared With The Alternatives

Versus Single-use syringe filters

Reusable holders reduce long-term cost per sample but require cleaning and carry a risk of carry-over if not properly maintained

Versus Solvent-bonded plastic holders

Injection-moulded PP holders avoid adhesive residues in the flow path, improving chemical compatibility and extractables profile

Versus Standard luer lock fittings only

Hosebarb fittings allow direct connection to tubing, reducing the need for adapters in industrial setups

Versus Single-layer holders

Double-layer holders support higher particle loads and longer run times without clogging

Use Guide

How To Use It

Select the holder diameter to match the membrane filter size (13 mm to 300 mm)
Choose PP for general lab use with non-aggressive solvents; use 316L stainless steel for corrosive or high-temperature applications
Match the connection type to your system: luer slip for syringes, luer lock for secure connections, hosebarb for tubing
For high-flow or high-load applications, select double-layer configurations
Clean thoroughly after each use with compatible solvents; rinse with water and dry before reuse
Inspect for wear or damage before each use; replace if seals or fittings show signs of degradation
