Decontaminators are technologies and procedures used in laboratory and clinical environments to eliminate or inactivate biological, chemical, and molecular contaminants from surfaces, instruments, and controlled spaces. In peer-reviewed literature on laboratory biosafety and contamination control, decontamination is consistently identified as a critical step for maintaining experimental validity, preventing cross-contamination, and ensuring operator and environmental safety, particularly in molecular biology, cell culture, and high-precision analytical workflows.
In advanced analytical systems such as electron microscopy and vacuum-based instrumentation, contamination—especially hydrocarbon deposition—can significantly degrade performance. Studies in surface science and electron microscopy demonstrate that organic residues within vacuum chambers can lead to imaging artifacts, reduced resolution, and beam instability. Plasma-based decontamination systems have therefore been widely adopted as an effective non-contact method for breaking down carbon-based contaminants into volatile compounds that are removed under vacuum conditions, restoring instrument performance without mechanical or chemical abrasion.
Similarly, in molecular biology and diagnostic laboratories, decontamination protocols are essential for eliminating nucleic acid contamination (DNA/RNA carryover), which is a well-documented source of false-positive results in PCR-based assays. Peer-reviewed studies in laboratory contamination control emphasize that effective decontamination strategies significantly reduce amplification artifacts and improve diagnostic reliability.
