By integrating a real-time particle sensor and automated ISO 5 air quality alerts directly into the chamber, TopAir’s Integrated Particle Monitoring System (IPMS) eliminates the critical laboratory blind spot where standard biosafety cabinets fail to detect active workspace contamination between annual certifications. Imagine a primary cell culture or delicate viral line that has been growing for two weeks, only to suddenly fail. The biosafety cabinet it was prepared in passed its last annual certification, the airflow velocity alarm never sounded, and everything appeared completely normal. The fundamental problem is that standard cabinets only monitor airflow speeds and filter pressure. Not whether the air surrounding your sensitive samples is actually clean.
TopAir’s Integrated Particle Monitoring System (IPMS) closes this dangerous gap, setting TopAir’s Class II biosafety cabinets apart as a true showstopper in contamination control.
The Invisible Risk in Standard Class II Cabinets
A standard Class II Type A2 biosafety cabinet is engineered to protect three critical elements simultaneously: laboratory personnel, the surrounding environment, and the sample. TopAir’s A2 cabinets achieve this using an airflow pattern of 70% recirculated downflow and 30% exhaust through high-efficiency HEPA or ULPA filtration rated at 99.9995% efficiency. The full range is CE certified and complies with EN 12469, with NSF-49 compliant versions also available.

How IPMS Hardware & Visual Alerts Work
Described as the world’s first integrated particle monitoring system built directly into a biosafety cabinet, TopAir’s IPMS provides continuous, 24/7 air cleanliness tracking:
-
Real-Time ISO 5 Cleanliness Tracking: Built-in optical sensors continuously sample the interior air volume to verify compliance with ISO 5 standards (≤3,520 particles of μm per cubic metre of air, per ISO 14644-1).
-
Smart Algorithm Processing: Raw sensor data is processed by an onboard microprocessor algorithm, translating complex particle counts into instant visual indicators rather than confusing raw numbers.
-
Fail-Safe Dual Visual Warning: If particulate levels exceed ISO 5 thresholds, the main digital control screen instantly turns red AND the internal chamber lighting switches to red, making the contamination warning impossible for operators to miss.
-
Automatic Recovery: As soon as downflow filtration restores workspace cleanliness to ISO 5 levels, the red internal lighting automatically turns off and the display returns to normal status.
Why Real-Time Monitoring is a Gamechanger
-
Proof Over Assumptions: Annual certification is merely a single-point snapshot. The IPMS provides an unbroken digital log of air cleanliness between service intervals, safeguarding quality assurance and audit compliance.
-
Instant Intervention: Instead of discovering cross-contamination days later during incubation, operators receive immediate alerts, allowing them to stop work, isolate media, and save valuable research.
-
Condition-Based Servicing: Maintenance is triggered by actual filter performance and particle load rather than arbitrary calendar dates, optimising filter lifespans and reducing operational downtime.
-
Comprehensive Environmental Oversight: The ergonomic touchscreen interface displays real-time downflow, inflow, particulate matter status, temperature, and humidity simultaneously, giving operators total confidence before starting work.
