Monmouth Scientific | Product | Class 2 Biological Safety Cabinet

Guardian Class 2 Biological Safety Cabinets

The Class 2 Biological Safety Cabinet utilises a specially ventilated enclosure, developed for sterile material handling and sensitive processes where biological samples are applied requiring a safe work zone, providing protection for the user, sample and surrounding environment.

Independently type tested and approved to BSEN 12469:2000 by the UK’s leading authority on BioSafety Cabinets, the Health Protection Agency at Porton Down.

ICON | Creating Clean Environments

H14 HEPA filters, 99.97% efficient at 0.3um offer Advanced Contamination Protection and an ISO Class 4 Clean Environment.

ICON | Tailored to Your Application

Choice of A2 (Recirculating) or C1 (Hazardous Chemical Use) Models in 3 widths (800 mm, 1200mm, 1800mm) to suit your application.

MonSci-Icons-ECO Mode

Power Output reduced, Lighting and Display Deactivated and Fan Speed Reduced to 50% after a period of operator inactivity.

Our Class 2 Biological Safety Cabinets keep your team safe while handling potentially hazardous materials.

Manufactured to the highest quality standards, our state-of-the-art biosafety solution is equipped with H14 HEPA Filters to create an ISO Class 4 Clean Environment and features an intuitive control system, energy-efficient LED lighting, controlled airflow and UV sterilisation functionality.

Class II Microbiological Safety Cabinets utilise a flow of air drawn via the front aperture into the cabinet. This inward airflow (personnel protection) prevents aerosols generated during microbiological processes from escaping through the front opening.

A vertical downward HEPA-filtered laminar airflow (product protection) cascades unidirectionally from the front face of the cabinet creating an air curtain while continually flushing the enclosure of airborne particles and ensuring the working sample is protected from contamination. The contaminated air then makes its way into a HEPA-filter system (environmental protection) before it is safely exhausted from the enclosure.

Class 2 Biological Safety Cabinets are suitable for work with microbiological agents assigned to Biosafety Levels 1, 2 3 or 4.

Touchscreen Control Interface

The Visionaire® technology built into our Biological Safety Cabinets allows the highest level of operator monitoring, giving you the ability to control every necessary aspect of product operation.


Infra-Red Intelligent Sash Safety (IRISS)

Our IRISS system projects an infra-red beam across the base of the opening, should this beam be broken the sash closure will be instantly and automatically aborted, preventing potential injury or damage.

Biosafety for Your Requirements

Class 2 Biological Safety Cabinets offer Three Levels of Protection. 

Air Inflow protects the Operator, HEPA-filtered Downflow prevents cross contamination and protects the Sample andHEPA-filtered exhaust protects the Environment.

Type A2

In a Recirculating Type A2 MSC air is drawn in through the front aperture, providing operator protection. The inflow air mixes with the downflow air as it enters the front intake grille and passes through the plenum where the air is split into exhaust systems.

  • 70% of the air is recycled and pushed back into the Work Area through the downflow HEPA Filtration, providing product protection.
  • 30% is returned through the Exhaust Air HEPA Filter back into the laboratory environment.

Type C1

A Type C1 MSC utilises the same airflow pattern as a Type A2. The addition of an Anti-Blowback Valve directs 30% Exhaust Air through an External Duct System.

Carbon Exhaust System

If chemicals are used a Carbon Filtered Exhaust system may be installed after or as part of the Exhaust HEPA Filter, making a Type A2 Cabinet suitable for the handling of hazardous chemicals.
