Biological Safety Cabinets » Class II Type B2 Model HFsafe 900LCB2/1200LCB2/1500LCB2/1800LCB2/Cabinets

Non-compromising safety


-  Patented Flow-saFe system automatically balances the downflow and inflow velocities to maintain user and sample protection.
-  You can keep a constant check on the airflow, window position etc.- anytime, anywhere.
-  When the front sash is closed, our intelligent speed control automatically reduces flow speed.
-  Negative-pressure, dual side walls prevent the possibility of contamination from leaks to the exterior environment. 

Enhanced comfort and convenience 



-  10 ° backward-slanted safety grade glass provides protection with more comfortable viewing than vertical sashes.
-  Counterbalanced sliding sash can be raised to a maximum height for easy introduction of large items.
-  The radiused edge prevents the potentially dangerous practice of placing materials in this area.
-  Constructed of seamless, non-porous, autoclavable Type 304 stainless steel for working plate, one-piece side/rear walls. 

UV Decontamination

-  Programmable UV light timer simplifies operation while extending life time
-  Powerful UV irradiation ensures thorough disinfection of the complete chamber.
-  UV lamp with interlocking safety switch function is designed for your safety.
-  Unique hidden UV lamp protects operator’ s eyes from hurt. 

Easy to Clean



-  The cabinet work zone has no welded joints to collect contaminants or rust.
-  Details of cabinet developed further to ensure easier cleaning with normal cleaning solvents
-  Airflow laminator protects the filter surface during wipe cleaning.
-  Optional multiple piece stainless steel work surface is easier to remove and put into autoclave / washer.
-  Bottom sink is made of stainless steel type 304 with round corners and draining valves 

How to set a new bechmark for the whole industry?

-  Supply and exhaust filters provide 99.999% typical efficiency for particle size of 0.1 to 0.2 microns, providing superior product protection over conventional HEPA filters.
-  German made ebm-papst motors selected for energy efficiency, compact design, and flat profile.
-  Temperature-compensated airflow sensors monitor the airflow constantly to ensure safe operating conditions are maintained.
-  Two independent sensors (downflow/exhaust airflow) mean double security. 

Friendly Communication

-   LCD is mounted at eye level for at-a-glance viewing of airflow, operating parameters, and alarm messages.
 -  The intuitive interface delivers a constant read-out of working area temperature, air velocity/volume, filter life span, total running time.
 -  Patented filter life indicator is designed to measure filter life according to actual condition of membrane. 

Exhaust Connection Design
If biosafety cabinets are used for minute quantities of volatile toxic chemicals and trace amounts of radionucleotides required as an adjunct to microbiological research, they must be exhausted through properly functioning exhaust canopies.
                  
Independent exhaust system                  Central exhaust system case 1                            Central exhaust system case 2

Central exhaust system case1: Applicable to the condition where air volume and pressure of central exhaust system are sufficient
Central exhaust system case2: Applicable to the condition where air volume is sufficient, while pressure of central exhaust system is not enough. Need to choose special designed exhaust blower to support the pressure requirement.
 
Constant air flow valve
-  Class II type B2 biosafety cabinet should be normally working under the condition when the exhaust air volume is consistent
-  It minimizes the potential air velocity fluctuation during work. Constant air flow guarantees your safety!



Electric anti blow back valve 

-  Electric anti blow back valve prevents air flow back to safety cabinet and cause air fluctuation
-  Valve can be synchronized open or closed with the power switch button of the cabinet


Comprehensive Performance Testing

Every HFsafe model manufactured by Heal Force is individually tested, documented by serial number and validated with the following test methods.

Inflow/Downflow velocity                             Air particle count test                                   UV radiation test


Scan test for filters                                        Vibration test                                Illumination test
 
KI Discus containment test according to EN12469 (Potassium Iodide)

One of the few companies in the world equipped to perform the KI Discus test for validating the operator/personnel protection capabilities 
Excellent correlation with the microbiological test method for operator protection, and is useful for validating the actual containment performance of the cabinet on-site.
The KI-Discus takes only 45 minutes as opposed to 2 days for microbiological testing. Thus, Each HFsafe model is factory tested on a sampling basis using the KI-Discus method for operator safety.
