====== Laminar flow hood ====== | ====== Presentation ====== |
The flow hood is a sterile air blower. The particles are separated from the ambient air by a prefilter, then by an HEPA filter. This results in clean air at 99.97%, which exerts a positive pressure on the work plan. | The flow hood is a sterile air blower. The particles of the air are separated by a pre-filter and a HEPA filter. This results in almost pure air, separated at 99.97% from particles greater than 0.3 µm. This clean air exerts a positive pressure on the work plan, allowing to easily produce axenic cultures. |
====== Prototype 1 & 2 ====== | ====== Prototype 1 & 2 ====== |
The first prototype met the expectations, but several details deserved to be improved. The plans, drawings and the budget of the second version are available below. | The first prototype met the expectations, but several details deserved to be improved.
