General

The protection chamber for weighing OK is designed for safe handling of dangerous pharmaceutical substances, mainly for laboratory weighing of small quantities and preparation of samples for analyses. The suction chamber with horizontal, laminar filter-directed air flow prevents the passage of material from the chamber into the environment and thus protects the operator and the environment. It is a precise weighing, sampling, filtration or any operation with open, especially highly active substances.

Working principle

The suction chamber works on 100% air exchange (the amount entering also exits the system - without recirculation). The chamber takes air from the surrounding area - the laboratory (from the front through the working aperture).

The air enters the workplace of the suction chamber from the front through the working aperture, using a fan mounted in the suction unit. The captured air then travels over the workplace and the first filtration quality H14 (EN 1822). Through outlet filters, the incoming air, which is contaminated with the substance within the working place, filters and purifies. The filtered air then returns to the place.

The first output HEPA filter quality H14 is installed directly behind the workplace. It is safe to replace the first output filters that are loaded with dangerous particles. The second output HEPA filter quality H14 is integrated into the suction unit and provides additional protection and assumes the role of air filtration in the event of a change or damage to the first or the other. the first two output filters. Through outlet filters, the incoming air, which is contaminated with the substance within the workplace, filters and purifies. The filtered air then returns to the place.

 

Control

The user screen is for visualization and more transparent management. It is located on the front of the chamber, next to  the user. Its basic task is to manage the system, display errors and manage service settings.
