Tianjia UV Sterilization Pass-Through Box: Safety Gatekeeper for Clean Zone Material Transfer

In pharmaceuticals, biological experiments, electronics manufacturing and other scenarios, material cross-clean-zone transfer is a high-risk cross-contamination link. Traditional pass-through boxes have incomplete sterilization, poor sealing and lack of control, failing ISO 1–8 strict requirements. Tianjia’s UV sterilization pass-through box features dual sterilization, intelligent control and ready-to-use.

I. Core Technical Highlights

Dual Sterilization Protection

Equipped with UV germicidal lamp and HEPA two-stage purification, UV quickly kills surface microorganisms, HEPA thoroughly intercepts particles, ensuring material surface and transfer air meet Class 100, eliminating cross-contamination. Ordinary pass-through boxes only have physical isolation.
Intelligent Interlock Design

Mechanical or electronic interlock, doors cannot open simultaneously, preventing airflow leakage. SUS304 stainless steel, double tempered glass windows, seamless and protrusion-free, easy to wipe with disinfectant wipes, withstands frequent alcohol disinfection. Simple pass-through boxes have no interlock.
Ready-to-Use

No complex installation, out-of-box use, compact size, quickly embeds walls of different thicknesses, customizable specifications. Optional dynamic laminar function for higher cleanliness. Fixed models cannot adapt to complex walls.
Full-Life-Cycle Cost Optimization

Antimagnetic, cold-resistant, heat-resistant, long filter and UV lamp life, maintenance every six months. Seamlessly connects with air showers and laminar flow hoods, 40% lower long-term cost than ordinary pass-through boxes.

II. Quick Selection Guide

Biosafety Laboratories / Vaccine Production (ISO 1–5): Dynamic laminar model with UV + HEPA + MES, for high-risk materials.
Pharmaceutical Workshops / Medical Device Production (ISO 6–7): Standard with UV + HEPA + interlock, for aseptic materials.
General Laboratories / Electronic Assembly (ISO 8): Basic with UV + interlock, for routine materials.

III. Installation Process

Confirm wall opening matches outer size, reserve 220V power.
Embed pass-through box into wall, seal gaps with cleanroom silicone.
Connect power, test interlock, UV and HEPA.
Pass particle test for cleanliness, train operators and sign acceptance.

IV. Daily Usage Notes

Check UV lamp and HEPA pressure difference weekly; replace filters if pressure difference exceeds standard.
Wipe interior and door with 75% alcohol in one direction; do not scrape stainless steel.
Stop use immediately for interlock failure or UV lamp off; use original parts.
Avoid heating equipment nearby; turn off power and cover windows and vents before fumigation.
