Wiperator

The transfer and persistence of materials is the basis for forensic science.  Our staff have studied this topic extensively and have published peer-reviewed papers on this principal. Transfer and persistence are also applicable outside the confines of forensic applications to a wide range of investigations, from the study of disinfectant or decontamination efficiency to durability and abrasion testing. To conduct these types of investigations, Microtrace is equipped with the Wiperator, a specially designed apparatus for wipe efficiency and abrasion testing. This device ensures reliability and precision beyond the capabilities of manual methods. The Wiperator delivers accuracy of results that not only meet the requirements of quality assurance and compliance testing, but can be compared between sample sets and even separate laboratories. This equipment is the basis for the ASTM International Standard Test Method E2967-15 (Assessing the Ability of Pre-wetted Towelettes to Remove and Transfer Bacterial Contamination on Hard, Non-Porous Environmental Surfaces Using the Wiperator).

The customizable pressure, time, speed, and substrate settings allows this equipment to be tailored for specific applications. Microtrace’s ISO accredited laboratory is equipped with a suite of analytical instrumentation to provide detailed support of the Wiperator testing results, including UV-VIS-NIR imaging, as well as detailed chemical detection and quantification. Our scientists have developed tailored wipe efficiency comparisons, customized tests to evaluate disinfectant efficacy and longevity, and fiber shedding and other transfer and persistence studies.
