Is an incubator necessary for microbial testing?
Hello, I would like to purchase a microbial testing kit to test a few of my products, but the instructions require incubating at 35C for a day for bacteria and at 30C for 2 days for fungi. Is an incubator a necessity with these kits? Can an alternative be used - an oven or even leaving out at room temperature for a longer amount of time (I live in the tropics; it is 30C right now at 9pm at night) - or is precision regarding temperature and timing required for accurate results? Thanks.
