Microbial-Vac Systems has released the Microbial-Vac wet-vacuum collection system, which uses LAMDAC principles (liquid and air-assisted microbial detachment and capture) to collect laboratory or field samples — typically from one to two square-feet of surface area per sample in 100 to 150 milliliter liquid. The M-Vac is designed to sample this larger area while recovering higher levels of pathogens in each sample than traditional methods, the company said.
