Digital leak tester FIT-6.0

pressureflowimmersion

Brief description
FIT-6.0 Filter Integrity Tester is a compact, fully automated instrument for verifying integrity of sterilizing and process filters used in pharmaceutical and biotechnology applications. It performs manual and automated bubble point, enhanced bubble point, diffusion flow, pressure-hold and water-immersion tests for hydrophobic and hydrophilic membranes and ultrafiltration modules, meeting FDA, pharmacopeia and GMP requirements.

Features

• Automatic pre-wetting/infiltration routines to ensure complete wetting before flow tests and to protect downstream aseptic conditions for on-site testing.
• Real-time data acquisition of apparent diffusion flow with diffusion and viscous flow modelling to improve bubble point identification and correlation with bacterial retention tests.
• Measurement of actual upstream volume to quantify diffusion flow; supports water-based tests for hydrophobic filters to avoid residual organic solvent exposure.
• Large on-board data storage with SD card export and PC connectivity for extended archiving; exportable reports (Word, Excel, PDF) formatted for A4.
• Advanced control algorithms for instrument stability and test repeatability (approx. ±1% performance characteristics).
• Fully automatic digital gas inlet control—no manual valve adjustments during tests.
• Designed to maintain accuracy across large-diameter discs and long cartridges; compatible built-in parameters for Millipore, Sartorius and Pall systems.
• Alphanumeric batch entry and scientific electronic signature features to support GMP traceability and user accountability.

Main features

• Industrial dual-core processor and modern digital sensors for fast, stable operation.
• One-key program execution and simple reservation scheduling for routine workflows.
• Complete test curves and detailed data export; automatic/manual checklist printing of input parameters, results and curves.
• Rich I/O: RS232, USB and optional industrial bus/analog interfaces; SD/USB export for unlimited record management.
• Independent R&D support for custom program development and dedicated service team for technical assistance.
