Passive vs. Active Pass-Throughs: Material Transfer Best Practices

Episode Overview

Material transfer isn’t just about whether you unwrap first or disinfect first — it also depends on where the transfer happens. In this episode of Inside the Cleanroom, Christina Adkison and Patricia Igneczi discuss how passive and active/HEPA-filtered pass-through boxes work, why door interlocks matter, and how airflow can impact disinfectant wet contact time. They also explain why selecting the right disinfectant is critical for achieving microbial kill before materials move into a cleaner, more controlled space.
