BioCapt® Single-Use Microbial Impactor
Single-Use microbial impactor helps minimize false positives
The BioCapt® Single-Use Microbial Impactor is a lightweight, integrated air sampler designed for use with both portable and remote monitoring systems in remote sampling environments. Its single-use design reduces the risk of false positives and final product contamination associated with microbial sampling, while lowering investigation costs and avoiding non- conclusive results from traditional agar settle plates.
The innovative impactor design combines the media plate and sampling head into a single sterile, ready-to-use unit prefilled with medium, eliminating agar preparation, autoclaving, and stainless-steel head disinfection. Each unit minimizes handling and is supplied gamma-irradiated and double-bagged, with three units per package.
The single use impactor uses a radial slit design, validated at the Centre for Applied Microbiology & Research (CAMR), a Health Protection Agency (HPA) at Porton Down. It achieves isokinetic sampling for minimal air turbulence in compliance with ISO 146981 and can be used for sampling at 25 - 50 LPM. Potential for handling-related contamination is reduced through a simple process: the impactor is removed from the bag, installed in a portable or continuous monitoring system, and opened for sampling. After sampling, the lid is replaced and the unit is placed directly into the incubator. The lightweight design allows for easy one-handed operation.
