Accurate, reliable leak and burst testing for medical filters.

InterTech’s MED75y Leak Test System ensures the integrity of medical and sterilization filter assemblies, supporting both burst pressure and diffusive flow testing. Our solution is ideal for lab, assembly, R&D, and audit testing of sterilization filter membranes in the 0.05–0.2 micron pore size range.

Test Capabilities

  • Burst Pressure Testing

    • Test range: 2 – 70 bar maximum

    • Ramp rate: 1 bar per second (programmable)

    • Burst accept limit: 15 bar (model dependent)

    • Sequence: Gradual pressure increase with hold periods at 10 and 15 bar, continuing until burst occurs

    • Data traceability: 2D barcode scanning links each filter to the test record

  • Diffusive Flow Testing

    • Measures flow rates as low as 1.2 micron in 23 seconds

    • Typical limits: 10–20 µL/min depending on filter design

    • Applied pressures: 100–140 kPa gauge

    • Ideal for half-shell membrane filters or filters that cannot be bubble-tested

Features

  • 2D Barcode Tracking: Automatic scan ensures traceability and data logging directly to the MED75y instrument.

  • Compact Design: Minimizes footprint while maintaining easy integration in lab or production environments.

  • Cost-Effective: MED75y controls all functions, reducing wiring and eliminating the need for expensive PLCs or auxiliary components.

Applications

  • Diffusion and burst testing of sterilization filter assemblies

  • Lab-based R&D testing or assembly line audits

  • Filters that require precise diffusive flow measurement beyond the capabilities of traditional integrity testers (e.g., Pall Flowstar 5)

Technology

  • Diffusive Flow Basics:

    Diffusive Flow=k×Area×Differential Pressure\text{Diffusive Flow} = k \times \text{Area} \times \text{Differential Pressure}

  • Test pressures and flow limits are calculated based on bubble point and diffusive flow properties, including water and IPA testing parameters.

  • IDC Test Process Parameters:

    • Pressure range: 3 – 60 psig (other ranges available)

    • Instrument flow range: up to 350 µL/min full scale

    • Diffusion flow limits: 5 – 300 µL/min, depending on filter area

InterTech’s MED75y Medical Filter Leak Test System delivers fast, deterministic, and traceable testing—ensuring product quality, regulatory compliance, and safety for critical medical filtration devices.
