Air-Tight Damper; User-Supplied Microscope Requirements - Scope-Ready; Tm Package Only - Labconco Cell Logic+ B2 User Manual

Air-Tight Damper

The exhaust housing on a Type B2 biosafety cabinet is sealed to the top of the
biosafety cabinet. All of the biosafety cabinet's airflow is exhausted through the exhaust
housing by the facility's remote blower. The Cell Logic+ Type B2 biosafety cabinet
includes an air-tight damper as an integral part of the exhaust housing. See Figure 2-4.
The air-tight damper allows for fine adjustment of the exhaust air volume provided, in
order to correctly set the necessary exhaust airflow for each biosafety cabinet. It also
allows the biosafety cabinet to be sealed off from the building exhaust system, should it
become necessary to do so.

User-Supplied Microscope Requirements – Scope-Ready
If installing a microscope, locate the Stand-Still™ Isolation Platform in a separate box
shipped with the cabinet. The Stand-Still Isolation Platform supports the microscope on
top of the stainless steel work surface to eliminate up to 94% of vibrations and to
promote safe airflow. If using a stereoscope with a forward extending base, the
extended Stand-Still XL Isolation Platform should be ordered from
Accessories. Figures from Appendix E should be used to assist your set-up.
