Overview
The Labthink MFY-01 Vacuum Leak Tester is an engineered solution for deterministic, non-destructive package integrity verification based on the vacuum decay principle. It operates by subjecting sealed packages—submerged in water or placed within a controlled vacuum chamber—to a precisely regulated negative pressure environment. The instrument detects leakage through two complementary physical response modes: (1) visual observation of air bubble emission from submerged specimens under differential pressure, and (2) evaluation of dimensional deformation and elastic recovery behavior upon vacuum application and subsequent release. This dual-mode assessment enables robust pass/fail classification per internationally recognized test protocols, particularly for flexible packaging, blister cards, pouches, bottles, tubes, trays, and rigid containers used across food, pharmaceutical, medical device, and consumer goods supply chains.
Key Features
- Microprocessor-controlled vacuum generation with real-time digital display and intuitive PVC membrane keypad interface
- Precise vacuum setpoint programming (0 to –90 kPa) and programmable hold duration (0–999 s)
- Automatic pressure compensation via imported pneumatic control valves to maintain stable test conditions during extended dwell periods
- Integrated automatic vacuum termination and reverse-air purge cycle to safely depressurize the chamber and prevent sample distortion or water ingress
- Modular vacuum chamber design supporting three standardized configurations (Φ270×210 mm, Φ360×585 mm, Φ460×330 mm H), with custom dimensions available upon request
- Class 1 vacuum measurement accuracy per JJG 520–2019 (Chinese national metrological verification regulation), traceable to NIM-certified standards
Sample Compatibility & Compliance
The MFY-01 accommodates a broad spectrum of primary and secondary packaging formats—including vacuum-sealed meat trays, thermoformed blisters, aluminum-laminated pouches, HDPE squeeze tubes, glass vials with crimp seals, and corrugated folding cartons subjected to post-fall or compression stress. Its methodology aligns directly with mandatory regulatory frameworks: GB/T 15171–2023 “Method for Determination of Seal Integrity of Flexible Packages” and ASTM D3078–22 “Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission.” While not a quantitative leak rate meter, it satisfies routine QC screening requirements under ISO 11607-2:2019 (Packaging for terminally sterilized medical devices) and supports GLP-aligned documentation when paired with Labthink’s optional audit trail-enabled software module.
Software & Data Management
The MFY-01 operates as a standalone benchtop unit with embedded firmware; no PC connection is required for basic operation. For laboratories requiring electronic record retention and 21 CFR Part 11 compliance, Labthink offers the optional TS2100 Data Logger Suite. This Windows-based application provides time-stamped test logs, user access controls, electronic signatures, and immutable audit trails—including operator ID, vacuum setpoint, actual achieved vacuum, dwell time, pass/fail status, and timestamped operator annotations. All data exports in CSV and PDF formats, facilitating integration into LIMS or QMS platforms.
Applications
- Pre-shipment validation of vacuum-packed meat, poultry, and seafood trays prior to cold chain distribution
- Post-sterilization seal integrity verification of Tyvek®-laminated medical device pouches
- Leak screening of child-resistant pharmaceutical blister packs following ISTA 3A drop testing
- Process validation support for form-fill-seal (FFS) line qualification and change control activities
- Routine in-process checks during packaging line startup, shift changes, and after tooling adjustments
- Root cause analysis of seal failures in combination with peel strength and heat seal optimization studies
FAQ
Is the MFY-01 suitable for quantitative leak rate measurement?
No. It is a qualitative/semi-quantitative pass/fail tester based on visual or morphological indicators. For quantifiable leak rates (e.g., cc/min), consider helium mass spectrometry or pressure decay systems.
Does the instrument include a vacuum pump?
Yes — an oil-free diaphragm vacuum pump is integrated. No external pump is required.
Can the MFY-01 test dry, non-submerged samples?
Yes. The chamber-based method (non-immersion mode) evaluates seal integrity via observable expansion and recovery without water immersion.
What maintenance is required?
Annual calibration of the vacuum transducer and inspection of O-rings and sealing gaskets are recommended. Filter elements in the vacuum path should be replaced every 6 months under continuous use.
Is technical support available outside China?
Labthink maintains authorized service partners in North America, EU, and Southeast Asia, with remote diagnostics and on-site calibration support available under annual service agreements.
