Airborne microbes pose a potential risk of contamination for products and raw materials. Therefore, air sampling with active devices is a method commonly used for evaluation of particles, fungi, spores and microorganisms – even of viruses and bacteriophages. Sampling of a specific volume of air in a defined time can be performed with two different physical methods: filtration or impaction. Sartorius offers both solutions to suit your particular application. In addition, Sartorius defined growth media enable you to obtain qualitative and quantitative results.
