Dispensing / Sampling Booth 
| The Dispensing Booth is a containment solution for the weighing, the handling and the dosing of chemical and pharmaceutical active products with the operator outside the LAF (laminar airflow) area. This Dispensing Booth is a vertical laminar flow of Class M 3.5 (Fed. Std. 209 E) air, with a vertical return grid on the frontal side supplied with absolute filter on recovery and recirculation air. The cabinet is designed with part of the air re-circulate and quote of air exhausted outside, after absolute filtration. The operator and product protection by cross contamination between environmental / product and vice versa will be obtained with a physical containment into handling area powder, with a slight negative pressure inside the cabinet and a airflow barrier at level of front working aperture. The air front barrier is designed to permit an aspiration equal to 30% of the total air with a minimum air frontal velocity of 0.40 m/s and recirculation of the remaining 70% of the air on the working area in laminar air flow condition equal to a velocity of 0.45 m/s +/-20%. |
The sterility – cleanness of working area is guaranteed by a filtration of the air by absolute HEPA filter H14 and velocity of 0.45 m/s +/-20%. As far as product protection from the operator is concerned, it also relies on the down-flow of the HEPA filtered air, as well as on the appropriate personal protection devices like individual garments including mask, headgear, white coat, gloves and compliance with all the sanitary and safety regulations recommended in the Operating Manual of the Dispensing Booth and in the user safety procedures (like CGMP).
