Hi I want do standard Pm (Preventative Maintenance) for instrument and to do that I need to have PM check list as I check service manual in the documents section dont have it RE: Leica Biosystems - CM1850 UV
Our cryostat was working normally for the past year, easily maintaining -23C, then all of a sudden would not go below a temp of -9C. I decided to defosted it for 24 hours and it filled up the catch bucket overnight. But even after I had it back up and running for the last 8 hours, -9 is all she'll give me still. I noticed that the metal grate covering the cooling coils, just under the glass, is very warm. I know something keeps the glass warm, just don't remember it being that warm.Any info would be appreciated! John
