High Potency Injectable Drug

The high potency sterile injectable manufacturing line is located at the drug product site in Wuxi City, China. Its Occupational Exposure Limit (OEL) is 10 ng/m3. The fully enclosed isolation systems and automated filling machines minimize both microbial contamination and cross-contamination risks. The line has two 20m2 lyophilizers and supports liquid and lyophilized vials of various specifications. This line can efficiently perform the filling of up to 200 units per minute, achieving an annual capacity of over 12 million units.
