LabGard B1NU-427
Class II Type B1 Biosafety Cabinet

AIRFLOW VELOCITY DISPLAY | EXHAUST VOLUME DISPLAY | NSF/ANSI 49 MODELS | TOUCH PANEL INTERFACE

The NU-427 preserves the Class II Type B1 cabinet’s traditional role of serving as an intermediate option between recirculating and total exhaust cabinets but with a control system fit for modern applications. By exhausting air from the entire length of the back half of the work zone through slots in the back wall, this design not only allows users to continue the recommended practice of working “clean to dirty” and deep inside the work zone but also leaves the dished work surface intact to retain spills. This exhaust is powered by an external facility blower that is interlocked with the cabinet’s own motor through a redundant system to provide two layers of protection that minimize the risk of blowing air out of the cabinet should the external blower fail: cabinet exhaust is monitored by not only a mechanical pressure switch but also a differential velocity pressure-flow grid. A touch screen displays the readings from both this flow grid and a downflow sensor in the work zone at all times for the cabinet operator. Standard models meet the requirements of the respected NSF/ANSI 49 standard for biosafety cabinets.

TouchLink Electronic Control System for Class II, Type B2 Biosafety Cabinets

Manage Airflow Performance and Safety

TouchLink Control System

The airflow dynamics in an externally exhausted type B2 cabinet need to work in constant harmony. The TouchLink control system displays inflow velocity, downflow velocity, and exhaust volume on a single, easy to read front screen. The digital control system interlocks the downflow blower with the external exhaust to shut down the motor if an exhaust failure occurs—a safeguard that is further backed up by a mechanical pressure switch.

Digital exhaust flow grid for Class II, Type B Biosafety Cabinets

Ensuring Your Cabinet is in its flow

Digital Exhaust Flow Grid

The digital differential velocity pressure flow monitors exhaust to enable the TouchLink to derive not only inflow velocity but also the critical parameter of exhaust volume for display to the cabinet operator.

Biosafety Cabinet downflow thermistor airflow sensor.

Precision Product Protection

Downflow Air Sensor

The downflow sensor measures velocity inside the work zone and passes the data to the TouchLink display to assure users of product protection, a critical aspect in many pharmaceutical and biotechnology applications.

Keeping a Track Record

Performance History

The TouchLink control panel not only displays one week of cabinet performance on screen but also allows a full month of history to be downloaded to USB for procedures that must be carried out under documented airflow conditions.
