Weighing equipment
The weighing room distributes raw and auxiliary materials according to the process prescription. Only one kind of material is allowed to be weighed and prepared at the same time. In the weighing process, a large amount of dust will be produced, so pollution and cross pollution should be avoided to the greatest extent.
It is recommended to operate in an area equipped with a dust removal system to minimize the operator's exposure to the product.
At present, there is a relatively new dust removal method, which adopts local dust removal facilities. The system is equipped with primary, intermediate and high-efficiency filters, and operates in self circulation mode with vertical downward air outlet. This method can effectively control the dust from flying; all dust is collected on the primary effect filter bag, and the unified product is replaced regularly or according to the differential pressure indication, and different active ingredients are replaced Different filter bags can not only avoid cross pollution but also air pollution. For highly sensitized materials, it may be required to operate in a separate cabinet with half body or glove holes.
Cross contamination control through negative pressure environment option.
Full unidirectional airflow provides superior aseptic work zones.
GMP modular design with minimized joints and seams.
All components meet or exceed applicable safety requirements.
