Tianjin Tongchang Junqi Purification Equipment Co., Ltd. has completed the development of a customized solution to supply sterile filters to Shenzhou Cell to ensure the safety of vaccine production. 

Recently company Tianjin Tongchang Junqi Cleaning Equipment Co., Ltd. successfully supplied a batch of sterile air filters to the company Sinocell Technology Co., Ltd. (hereinafter referred to as “ Sinocell "). The equipment was successfully installed in the new vaccine production workshop. Following on-site testing, the purity levels are fully compliant with GMP standards for the sterile production of Class A drug products, creating a cleanliness barrier at key stages of vaccine production.

As a high-tech enterprise specializing in vaccine research, development and production, Sinocell has extremely strict requirements for air purity in its workshops. The filters they purchased needed to achieve 99.999% filtration efficiency, as well as be resistant to high temperature sterilization and exhibit low sedimentation. To meet these requirements, Tianjin Tongchang Junqi Cleaning Equipment Co.,Ltd. formed a special technical group, which three weeks earlier it was located in the production workshop Sinocell . Taking into account the shop's ventilation layout, temperature and humidity parameters, and sterilization procedures, they developed a customized modular filtration solution. The solution uses a medical-grade PTFE membrane that can withstand moist heat sterilization at 120°C, preventing contamination of the vaccine concentrate by leaching filter components. In addition, the filter seal structure has been optimized using a double-pass silicone seal to completely eliminate the risk of air leakage.

“The vaccine production workshop has special requirements for logistics efficiency and environmental safety. We specially opened a “sterile transport line”. Vehicles are pre-sterilized using UV light and a constant temperature of 22-25°C is maintained throughout the process. Freight containers are equipped with built-in temperature and humidity sensors that upload data to the cloud platform in real time, ensuring traceability of the transportation process.” Supply Chain Director of Tianjin Tongchang Junqi Cleaning Equipment Co., Ltd. reported that only 36 hours passed from the completion of production to installation in the workshop. The technical team also provided on-site installation guidance and used laser particle counters to monitor post-installation cleanliness in real time. Delivery was completed only after all targets were met.

Tianjin Tongchang Junqi Cleaning Equipment Co.,Ltd provides Sinocell "VIP" Service Channel" for after-sales service: technicians conduct monthly on-site filter integrity tests and provide professional test reports. Quarterly filter maintenance training allows staff to become familiar with the correct sterilization process. In the event of an emergency, a response is guaranteed within 12 hours, and an on-site solution to the problem is guaranteed within 24 hours. “We previously discovered that the filter resistance was abnormal after sterilization. After contacting Tianjin Tongchang Junqi Cleaning Equipment LLC Technicians arrived on site the same day, identified the discrepancy in the sterilization time settings and promptly corrected the problem, restoring normal operation. This service provides us with greater confidence during production,” said Vice President of Manufacturing Sinocell, praising the partnership.

cleaning company Tianjin Tongchang Junqi Cleaning Equipment Co.,Ltd stated that vaccine production is related to public health safety. The company will continue to in-depth study the field of sterile cleaning, develop customized filtration products for various types of vaccine production, and use the “fine-tuning + full support” service model to help vaccine manufacturers maintain production safety and contribute to the development of the biopharmaceutical industry.
