We recently use a very handy testkit to check the microbial contamination inside the fueltanks of the 737. This test is done during a c-check and in the past we had to collect fuelsamples and send them to an expensive test-lab to get the results, after 1 or 2 days. Now we use a testkit named FUELSTAT RESINAE PLUS from Conidia which gives us a quick result on the fuelsamples taken from each fueltank. The testkit has a sample bottle and a test-paddle. This paddle gives you the result within 10 minutes ! Full description and usage of this kit can be found on the website of Conidia at http://www.conidia.com/aviation-products-services/. See the animation video below for a short impression.
