Application case of weighing hood products —— freeze-dried powder injection production

Freeze-dried powder injection is a preparation form of medicine. After dissolving medicinal ingredients (raw materials) and auxiliary ingredients (excipients) in a solvent (such as water), it is prepared into a solution of a certain concentration, which is divided into ampoules or cillin In containers such as bottles, freeze at low temperature in a sterile airtight environment, and then sublimate the solvent (such as water) in the product by lowering the ambient air pressure and slowly increasing the temperature of the product, leaving a loose block or powder in solid form Formulations of drugs. When using, it is necessary to add a vehicle (such as water) to dissolve the drug into a solution and then use it for injection or infusion to treat diseases.

Freeze-dried powder injection is a drug for direct injection into the human body, so the entire production environment must ensure a certain level of cleanliness, and the containers, equipment, and packaging materials used in production must be processed to ensure sterility and pyrogen-free. In order to meet the production environment of freeze-dried coupon injections, in addition to clean rooms, the production workshop also needs to be equipped with weighing hoods, laminar flow hoods, isolators and other equipment to meet higher cleanliness requirements.

The clean weighing hood can provide a self-circulating negative pressure clean micro-environment. This system prevents cross-contamination and protects operator safety during weighing or sampling of pharmaceutical raw materials. The weighing hood is equipped with an intelligent information processing device, automatic operation, automatic weighing, label printing, and data storage, and cannot be modified after storage, reducing human operation errors and ensuring data accuracy. More in line with FDA/CGMP/GMP regulations.

Therefore, the weighing hood plays a very important role in the production process of freeze-dried powder injection, and is mainly used in the weighing of raw materials and activated carbon. The weighing hood ensures a sterile environment in the production process of freeze-dried powder injection and ensures the quality.
