BMB-II-"Laminar-S."-1,2 SAVVY SL Class II Biological Safety Cabinet
The microbiological safety cabinet Class II SAVVY SL is designed for work with agents of biosafety levels I, II and III. It provides product, operator and environment protection.
Savvy SL is a new generation of the microbiological safety cabinets that inherited all the advantages of the previous models.
KEY BENEFITS
POWER DRIVEN FRONT SASH.
Five specified positions of the front sash:
- Operating position is settled in accordance with EN 12469
- Completely closed position is used in Stand-by Mode
- Down position – for cleaning and disinfection
- Up position – for loading the working chamber
- Stop before closing
FRONT SASH STOP PRIOR TO CLOSING. Automatic stop of the front sash at 40 mm height from the surface prior to complete closing of the front opening prevents any injury of the operator’s hands.
STOP AHEAD OF OBSTACLE. To ensure maximum safety, the moving front sash automatically stops in case of contact with an object or a hand of the operator.
MICROPROCESSOR CONTROL SYSTEM. The cabinet is featured with a microprocessor control system that immediately informs an operator on the reduction of the level of the cabinet protection via alarm messages displayed on the touchscreen and via an audible and visible alert.
The fan motor control system SintelL-1 minimizes the power consumption of the operating cabinet as well as reduces the level of acoustic and electromagnetic noise.
The system of static airflow stabilization AIS LS automatically maintains the air balance in the work chamber increasing the fan rpm as filters get clogged. Upon reaching the clogging threshold, the alarm is activated.
Mode monitoring system featured with audible and visible alarm indicates any disturbance of the air balance in the work chamber.
AUDIBLE AND VISIBLE ALARM SYSTEM. Alarms are automatically activated in case the airflow parameters deviate from the preset values.
LOW LEVEL OF NOISE.
TOUCHSCREEN CONTROL PANEL. It ensures clear visualization of operating modes and simple control of the cabinet as well as provides the user with more service and maintenance information. The screen allows for work in gloves and disinfection with liquids, i.e. hydrogen peroxide.
