 +====== Laminar flow hood ======
 +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.

 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.
