BMB-II-Laminar-S.-1,2 VIS-A-VIS
Microbiological safety cabinet class II VIS-A-VIS is designed to work with lab animals.
The design of VIS-A-VIS cabinet allows two operators working opposite one another at the same time.
It provides product, operator and environment protection when working with agents of biosafety levels 1, 2 and 3.
MAIN FEATURES
It is equipped with a system of monitoring the operating modes; optical sensors of the front glasses, the UV-unit and the safety closure position; a control panel with LCD touch screen, where operation information of the cabinet is displayed. The audio-visible alarm system is activated upon failure of the safety conditions.
Downward laminar air flow prevents the materials cross contamination in the working zone. The animals’ hair catcher is installed under the table top.
A unique pull out UV-unit is included into the basic configuration.
The cabinet is designed for operation in standing or seating position.
Support stand for operators in standing position (height of the working surface is 1,008 mm) .
