I. Core Technical Highlights

1. High-Quality Stainless Steel Structure, Adapting to Biological Scenarios

    

   304 stainless steel structure, 1.0–1.2mm thickness, special antibacterial treatment, 40% higher corrosion and antibacterial resistance than ordinary carbon steel models, adapting to humid and bacteria-prone biotechnology laboratories, complying with GMP, CE standards.
    
2. Low-Noise Operation, Ensuring Experimental Precision

    

   Silent fan and shock-absorbing structure, operating noise ≤50dB, 30% lower than ordinary pass-through boxes (≥70dB), avoiding interference with cell culture, PCR and other precision experiments.
    
3. HEPA + UV Dual Protection

    

   HEPA filter and UV germicidal lamp, completing sample surface sterilization in 30 seconds, 80% lower pollution risk than single-filtration models, protecting samples from microbial contamination.
    
4. Electronic Interlock System, Preventing Cross-Contamination

    

   Electronic interlock, door switching response ≤2 seconds, completely blocking air circulation, 60% lower misoperation rate than mechanical lock models, avoiding cross-contamination.
    

II. Quick Selection Guide

1. Cell Culture Laboratories: Low noise + HEPA + UV, ensuring quiet and clean sample transfer.
2. Genetic Testing Centers: High-quality stainless steel + electronic interlock + transparent windows, for high-frequency reagent and sample transfer.
3. Vaccine R&D Laboratories: Low noise + high-efficiency purification + no installation, meeting quiet experiment needs.
4. Biopharmaceutical Workshops: Antibacterial stainless steel + fast interlock + large size, for bulk material transfer.

III. Installation Process

1. Confirm size (standard 400×400×400mm or customizable).
2. Take out pass-through box, place or embed into wall.
3. Test electronic interlock, UV and HEPA, ensure noise and purification meet standards.
4. Airtightness and response testing, train operators.

IV. Daily Precautions

1. The HEPA filter shall be replaced every 1 to 2 years, and the primary filter every 3 to 6 months to ensure stable high-efficiency purification performance.
2. Wipe stainless steel surfaces and transparent windows with 75% alcohol daily; turn on the ultraviolet disinfection lamp for more than 30 minutes every week.
3. Inspect the fan and damping structure quarterly to ensure the operating noise is ≤50dB and prevent increased noise caused by component wear.
4. In case of interlock failure or filter alarm, contact the 24-hour after-sales support for quick parts replacement and service recovery.
