18 – WHY IS SUGGESTED TO ADOPT AN ACTIVE AIR SAMPLER WITH 2 OR 3 ASPIRATING HEADS INSTEAD THAT JUST A SINGLE ONE?


There are several advantages:

  • The use of different media at the same time (e.g.: TSA for bacteria and SDA for moulds)
  • The use of the same media for real statistical results
  • The use of the same media (e.g.: TSA) at different incubation temperature for bacteria and moulds
  • To save operator time
  • The application of continuous monitoring during the daily working shift
  • To reduce the operator contamination risk because the plates handling is reduced
