Application Scenarios and Precautions for Sterile Negative Pressure Filling Isolator

The core application of the Sterile Negative Pressure Filling Isolator focuses on the full lifecycle production of sterile, highly toxic, and highly potent preparations, covering every stage from R&D to large-scale manufacturing.

1. R&D and Testing Scenarios: Suitable for small-scale and pilot trials in pharmaceutical companies and research institutions, primarily targeting the development and trial production of various sterile injections and biological preparations.

2. Highly Toxic and Potent Preparation Production: This is the core application area of the equipment, specifically serving high-risk products.

3. Special Sterile Preparation Production: Designed for special preparations with extreme cleanliness requirements, such as lyophilized (freeze-dried) preparations, high-end biological products, and radiopharmaceuticals.

4.Compliance Production Scenarios: With the continuous upgrading of GMP standards, isolator equipment helps enterprises easily pass GMP and other industry standard audits, thanks to its comprehensive validation system, real-time environmental monitoring data, and traceable electronic operation records.

The long-term stable operation of a negative pressure isolator relies on standardized operating procedures and rigorous maintenance. Relevant precautions should be clarified from the following five dimensions:

1. Operational Precautions

(1) Qualifications and Training: Operators must undergo systematic professional training and pass assessments before they are allowed to operate the equipment.

(2) Pre-production Inspection: A comprehensive spot check must be completed before startup. Key steps include using a wireless leak detector to test glove integrity, confirming good chamber sealing, ensuring pressure parameters are met, and verifying that the sterilization system is ready.

(3) Monitoring and Wrap-up: During production, key parameters such as pressure, temperature, humidity, particle counts, and airborne microbes must be monitored in real-time. After production, strictly follow protocols for cleaning and sterilization, cut off energy supplies, organize the site, and archive batch records.

2. Daily Maintenance Precautions

(1) Daily Maintenance: Visually inspect the condition of sealing rings and gaskets to ensure there is no aging or damage; check the flexibility of air valves and pressure balancing devices; clean residues from the inner walls of the chamber and glove surfaces.

(2) Weekly Maintenance: Perform deep cleaning on airflow deflectors and chamber surfaces; conduct pressure decay integrity tests on gloves and sleeves; clean dust accumulation in the sealing grooves.

(3) Monthly Maintenance: Perform a chamber tightness test to ensure the leakage rate meets standards; check the pressure drop across HEPA filters and replace them promptly if resistance exceeds limits or alarms trigger; calibrate the interlock function and sealing of the RTP transfer device.

(4) Cleaning and Spare Parts: Strictly follow ISO and relevant cleanroom standards for disinfection. Be sure to drain accumulated water after cleaning to prevent corrosion, and establish a dedicated library for cleaning tools. Additionally, sufficient critical spare parts must be stocked.

3. Periodic Calibration Precautions

(1) Cycle Management: Develop a calibration plan based on GMP and equipment manual requirements.

(2) Execution Standards: Calibration must be performed by qualified professionals.

(3) Exception Handling: If deviations are found during calibration, the impact on the quality of previous product batches must be assessed immediately. Production must be suspended, and the equipment debugged or parts replaced. Production can only resume after recalibration passes.

(4) Sterilization System Special Calibration: Regularly perform performance verification on the VHP sterilization system, focusing on checking for drift in hydrogen peroxide concentration sensors, risks of pipeline crystallization blockage, and the temperature of the catalytic converter.
