Beijing Wantai Biological Pharmacy Enterprise Co., Ltd. (Wantai BioPharm) was founded in 1991 and is a high-tech enterprise specializing in the research, development, and manufacturing of in vitro diagnostic reagents and vaccines. Guided by its mission of “contributing to human health”, Wantai BioPharm is committed to transforming advanced biotechnologies into high-quality products that serve public health worldwide.
The company operates seven subsidiaries, with a diversified product portfolio covering automation systems and production lines, biochemistry, chemiluminescence, ELISA, colloidal gold assays, molecular diagnostics, raw materials, quality control products, and vaccines.
In 2005, approved by China’s Ministry of Science and Technology, Wantai BioPharm partnered with Xiamen University to establish the National Institute for Diagnostics and Vaccine Development (NIDVD). The center serves as a critical bridge between scientific research and industrialization, accelerating the commercialization of diagnostic reagents and vaccines while significantly shortening product development cycles and advancing China’s diagnostics and vaccine industry.
Hangzhou Wantai Biotechnology Co., Ltd., a key subsidiary of Wantai BioPharm, is a leading innovative biopharmaceutical company dedicated to the R&D and production of vaccines, diagnostic reagents, and biopharmaceutical products.
Its newly constructed large-scale manufacturing campus consists of multiple production buildings and dozens of cleanrooms and laboratories with different cleanliness classifications. Such a complex production environment places extremely high demands on time accuracy, consistency, and compliance.
Large Spatial Scale
Absolute time consistency must be maintained across different workshops, floors, and buildings.
Strict Regulatory Compliance
Time stamps must meet GMP, FDA, and international regulatory requirements, ensuring accuracy, traceability, and tamper resistance for electronic records.
Cleanroom Environment Requirements
All equipment must comply with dust-free, sterile, and easy-to-clean cleanroom standards.
Diverse Application Scenarios
Production areas, corridors, changing rooms, and control rooms require different clock types and display formats.
Wantai BioPharm required a fully integrated, highly compliant time synchronization system, not just individual clock products, to address these challenges.
After in-depth analysis of Wantai BioPharm’s operational and regulatory requirements, Changsha Tianqiong Electronics designed a comprehensive, modular solution combining:
Satellite-Synchronized Master Clock + Embedded Digital Cleanroom Clocks + Analog/Digital Slave Clocks
This solution ensures complete coverage of all production and auxiliary areas.
A high-precision GPS/BeiDou dual-mode satellite master clock was installed in the central control room/data center as the single authoritative time source for the entire campus.
Receives satellite signals to obtain national standard time with millisecond-level accuracy
Distributes time to all systems and clocks via the plant network using the NTP protocol
In critical clean production areas, including sterile workshops, aseptic laboratories, and QC testing rooms, embedded digital cleanroom clocks from Tianqiong Electronics were installed.
Key Advantages:
Flush-mounted, seamless integration with cleanroom sandwich panels
No hygiene dead corners; extremely easy to clean and disinfect
Clear, highly visible display providing operators with precise, real-time time references
Ensures accurate batch production and inspection time records
In corridors, lobbies, gowning rooms, and packaging areas, large analog or digital slave clocks were deployed.
Key Advantages:
Automatically synchronized with the master clock via wired or wireless transmission
No manual adjustment required
Large display surfaces ensure clear readability from long distances
Sealed cleanroom-grade design provides dust-proof and moisture-resistant protection
The entire clock system is seamlessly integrated with Wantai BioPharm’s:
MES (Manufacturing Execution System)
LIMS (Laboratory Information Management System)
Video surveillance systems
This integration provides a unified, authoritative time reference for all electronic records and monitoring data.
Following implementation, the customized solution delivered significant operational and compliance benefits:
Campus-Wide Time Unification
From R&D to production, and from core zones to auxiliary areas, all facilities now operate under a single, synchronized time standard, eliminating risks caused by time discrepancies.
Full Regulatory Compliance
Precise, traceable timestamps fully meet stringent domestic and international GMP and FDA audit requirements, safeguarding product quality and data integrity.
Improved Management Efficiency
Automated synchronization replaces manual calibration, simplifying maintenance and significantly reducing long-term operating costs.
Cleanroom Compatibility
All clock devices comply with cleanroom standards, ensuring both time accuracy and environmental cleanliness.
Enhanced Corporate Image
A unified, precise, and standardized time system reflects Wantai BioPharm’s rigorous, scientific, and efficient management philosophy, reinforcing its modern enterprise image.
The Facilities Manager commented:
“Our cleanrooms vary greatly in size and classification, making time synchronization extremely complex. Tianqiong Electronics did not offer a ‘one-size-fits-all’ solution. Instead, they conducted on-site studies and delivered a truly tailored combination solution. From the master clock to embedded clocks and slave clocks, each component precisely addressed specific scenarios. This system is not just a tool—it is a foundational element of our quality management system. Its stability and professionalism have earned our full trust.”
The successful collaboration with Hangzhou Wantai Biotechnology Co., Ltd. highlights Changsha Tianqiong Electronics’ deep technical expertise and customized solution capabilities in cleanroom and regulated pharmaceutical environments.
Tianqiong Electronics has evolved beyond a clock equipment supplier to become a strategic partner, helping enterprises enhance compliance, optimize operations, and strengthen quality management systems. Through high-reliability, end-to-end time synchronization solutions, Tianqiong Electronics continues to support the high-quality development of China’s biopharmaceutical industry.
