Not exactly the same, but very similar. We had an automatic stainer by the sink and one of the techs was washing glassware, the stainer was running. The water apparently splashed on the wiring and a fire broke out. We jumped into action. Just as we had been in-service. You are correct

Hello, I'm glad that you already solved the problem your way. I didn't read your first post, but we had exactly the same problem (and we're also using cover plates). This artifact is very likely caused by tiny air bubbles which are trapped under the cover plate. The crucial step is when you drip

One of those chemicals could have been chromic acid which will ignite when alcohol is introduced. One of my techs cleaned up the counter with alcohol after measuring chromic acid and we all ran for the extinguisher. She just stood there and shook her hands and stared at the flames. This was

A poor fixation will affect all the cell components. You may have a result but if the fixation is incomplete, the results will not indicate the real amount. At least 8 hours of fixation will be required. René J. --- On Fri, 2/26/10, Diana McCaig dmcc...@ckha.on.ca wrote: From: Diana McCaig
