Stupid me.... I bidded on Ebay on what I thought was an egg incubator. It's not, its a microbiology incubator & used. My other 2 incubators are both scrapped, they broke, a brinsea eco at £65 & some chinese import thing that ran at too low a temp at £50. Apparently this specific type of incubator was used to do something with chemicals & water & nothing would (should) have been placed directly in it. I have bleached the thing. Its part of a test kit apparently. I've been waiting for ages for it to show up because I had quail eggs sitting on the side that needed incubating ASAP & It was cheap at £20. But I'm concerned - it is a fan incubator, but I don't think its designed to run with the lid open, but if I shut the lid there is not ventilation. There is a second clear plastic lid over the incubating section. Also the temp at one end (nearest the heat source) reads 43oC whilst the other end furthest from the heat source reads 37.5oC. At the moment its running with the case lid open & the plastic lid on like below: I could always drill holes in the lid, but I don't want to damage it incase I need to return it. But even if I get my money back, I'm a long way off being able to afford a new incubator because the egg ones are just so expensive for some reason. Apart from the above, its running like an egg incubator. DH is more concerned about what might have been kept in it.
