Pass Box 2025: No More Wiping Doors and Walls with 70% Alcohol Every 5 Minutes!
Introducing 7 new Iranian and international pass box models that self-sterilize with UV-C + plasma + ionization.
Ordinary pass box = No. 1 source of secondary contamination in cleanrooms! In this article, you'll see 7 2025–2026 pass box models that fully sterilize in 45 seconds, eliminating the need for alcohol spray and wipes.
In November 2024, a well-known medical diagnostic laboratory in northern Tehran (we won't mention the name) was close to losing its molecular license due to recurring PCR contamination (almost weekly False Positives). After 3 months of investigation and sampling, they finally discovered: The source of external DNA and RNA contamination was precisely the ordinary pass box between the extraction and amplification rooms! Because every time the operator opened the door, their hand touched the handle, then touched the kit inside with the same hand. Alcohol wiping was forgotten every 2 hours!
Solution? A new 2025 pass box that self-sterilizes 100% in 45 seconds, without human intervention.
The above story is just one example. In 2025, no professional cleanroom operates without a "self-sterilizing" pass box.
Why Were Ordinary Pass Boxes Officially Banned in 2025?
The Food and Drug Organization and General Directorate of Medical Equipment announced in the October 2025 circular: "Pass boxes without active sterilization system (UV-C 254 nm or H2O2 plasma) are not permitted in Grade A and B cleanrooms."
Reasons?
- 92% of secondary contaminations come from internal door surfaces and handles
- 70% alcohol only lasts 30 minutes, then evaporates
- Disposable wipes themselves are a source of fibers!

- Cold Plasma → Produces OH and O radicals that kill even Bacillus spores
- Negative Ionization → Pulls suspended particles inside the pass box to the ground, preventing escape
- RFID lock + Internal camera → Only authorized card opens door + Full cycle recording
- Material presence sensor (UV cycle won't start if vial or syringe inside)
