Class II Type A2 Biosafety Cabinet
THREE-TIERED HEPA FILTRATION | EN 12469 & DIN 12980 MODELS | AIRFLOW VELOCITY DISPLAY | TWO AIRFLOW SENSORS
The NU-581 LabGard® is designed for work with cytotoxic powders by incorporating an additional tier of HEPA filtration underneath the work surface and closely monitoring cabinet performance with two airflow sensors whose data is displayed on a touch panel. Technicians can further document and analyze cabinet performance by downloading historical parameters onto a USB drive and configure the cabinet’s functioning with set up options. Meant to serve the most demanding pharmaceutical customers around the world, models are available that meet the EN 12469 and DIN 12980 standards respected in Europe.

Control Real Time Airflow
TouchLink Control System
The TouchLink control system calculates inflow velocity based on the data received from the exhaust airflow sensor and displays it alongside the readings from the downflow sensor on the front panel. Touch screen control, historical monitoring, and configurable settings enable users to manage airflow when performance must be demonstrated and recorded.

Straight to the Point
Thermistor Exhaust Sensor
A single dual-thermistor airflow sensor in the exhaust measures airflow to enable the FlowGard to calculate inflow velocity for users desiring the most straightforward measurement of cabinet containment performance.

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.

THIRD STAGE'S THE CHARM.
THIRD TIER OF HEPA FILTRATION
An additional tier of HEPA filters under the work surface optimizes the cabinet for work with cytotoxic powders and easy filter changes.
