Compendium of the Classification Opinions

Laminar airflow cabinet used for the preparation and handling of cell cultures in laboratories, etc., and consisting of a metal cabinet containing :

(i) an air recirculating hood incorporating an electric fan and a filter to purify the air;

(ii) a perforated sheet located below the hood to serve as a work surface;

(iii) a tank beneath the perforated sheet to collect any spilled liquids. The cabinet is open at the front and is designed to be placed on a workbench or table. The hood sets up a laminar airflow which creates a protective barrier at the opening of the cabinet to shield the operator from any possible contamination while handling biological material.

Cabina de flujo laminar utilizada para la preparacion y manejo de cultivos de celulas en laboratorios, etc, consiste en una cabina de metal que contiene:

1) Una campana aspirante que incorpora un ventilador y un filtro para purificar el aire

2) Una superficie perforada que sirve como superficie de trabajo (area de trabajo)

3) Un tanque debajo de la superficie para recolectar liquidos que derramados

"La campana produce un fjlujo de aire laminar que crea una barrera protectora en la abertura del cabinete para protegere al operador de cualquier contaminacion posible al manejar material biologico".
