Logic+ Biological Safety Cabinet, Class II, Type A2

Labconco Purifier® Logic®+ Biological Safety Cabinets, Class II, Type A2

The Purifier Logic+ Class II A2 Biosafety Cabinet excels in user comfort and functionality. Decades of industry leading advances in ergonomic design have shaped the Inclination™ Technology Suite that includes the following: 10° angled sash, patented curved air grille with built in armrest, fully accessible controls and eye-level mounted color display with MyLogic™ operating system.

MyLogic provides intuitive programming, color coded menus, status messages and alarms with diagnostic troubleshooting, all using clear messages and imagery. Using ECM blower technology, the Logic+ uses the Constant Airflow Profile™ (CAP) to maintain a precise volume of air as the filters load. In addition, the cabinet will continuously display the HEPA filter life remaining and cabinet status. These features combine to provide unparalleled safety.

These biocabinets provide excellent protection to personnel, product and environment. They are suitable for work in all levels of biosafety. Labconco's biological safety cabinets will discharge HEPA-filtered exhaust air directly into the laboratory or, if preferred, into an exhaust system through the optional Canopy Connection. Some models have optional base stands and/or an accessory packages (such as UV light, service fixture(s) and Vacu-Pass™ Cord and Cable Portal.)

A2 BioSafety Cabinets feature approximately 30% exhausted air and 70% recirculated air.

The room air is drawn into inlet grille. Air in the plenum beneath the work surface is a mix of unfiltered room air, and air from the work area. The blower draws this contaminated air through the back plenum of the cabinet, where approximately 70% of the air is recirculated through the supply HEPA filter and back over work area. The remaining air is discharged to the environment after passing through exhaust HEPA filter.

Efficiency with ECM.
Electronically Commutated Motor (ECM) blowers have many perks over conventional BSC motors:

• Consumes 60% less energy (see table below)
• Quiet operation (<63 dBA)
• 50,000 hour average motor life
• Reserve power for extended filter life
• Generates less heat for cooler working conditions

Airflow stability with CAP.
Constant Airflow Profile (CAP) monitors and maintains ECM airflow. Speed and torque are constantly adjusted to keep airflow within 1% of original calibration. CAP outperforms differential pressure gauges and airflow sensors. How? Gauges and sensors require manual adjustment by a certifier when a decline in airflow is detected. A certifier can only verify safe airflow for a single moment in time. With CAP, safe airflow is assured all the time.

Safety.
The Logic+ goes beyond the current conventional Biosafety Cabinet (BSC) standards. A line-of-sight display for feedback on your cabinet's safe operation while seated. A filter life display instead of confusing pressure readings. Alerts and alarm messages are shown in full sentences.

Performance.
Built-in system intelligence accurately maintains proper airflow, even as the HEPA filters load. This precision is achieved by pairing an Electronically Commutated Motor (ECM) with our exclusive Constant Airflow Profile™ (CAP) Technology.

Comfort.
Labconco has been at the forefront of BSC design for decades. Consider the angled sash they pioneered in 1983. It gives closer viewing without glare. Every feature is designed to account for human interaction with the cabinet.
