The negative pressure weighing room is mainly used in the weighing, batching, and packaging stages of materials that are dusty, toxic, highly reactive, allergenic, and of high value. The core purpose is to prevent dust from spilling out, protect personnel and the environment, and prevent cross-contamination. The typical application scenarios are very concentrated:
1. Pharmaceutical industry (main application)
Raw material drug (API) weighing
Antibiotics, hormones, cytotoxic drugs, highly active drugs batching.
Solid dosage form workshop
Raw and auxiliary materials weighing and pre-mixing for tablets, capsules, and granules.
Traditional Chinese medicine factory
Weighing of fine powder and extract powder of traditional Chinese medicine to prevent powder flying and pollution.
GMP clean area support
For local negative pressure operations in D-level, C-level, and B-level clean areas.
2. Biosafety and laboratory scenarios
Laboratory reagent weighing
Toxic chemicals, volatile, allergenic chemical reagents.
Microbiology / biological laboratories
Preventing the diffusion of bacterial powder, toxins, and biological active substances.
Research and development pilot, pilot lines
Microscopic high-active material operations during new drug research and formulation testing.
3. Fine chemical and cosmetics industry
Fine chemical raw materials
Pesticide intermediates, dyes, pigments, catalysts, etc. dust materials.
Cosmetics / health supplements
Weighing of nutritional powder, efficacy raw materials, allergenic additives.
4. Other dust control scenarios
Veterinary drugs, feed additives
Batching of highly active drugs.
Food additive industry
High-purity, prone to contamination, and safety-risk food additives weighing.
