The 100% alcohol on our processor has been contaminated lately and I have been unable to pinpoint the cause.
Our processor recently had a PM and checked out ok. The alcohol was cloudy when tested with water, which is how we normally test for purity before/after the recycler. I was told by the manufacturer that I should check the alcohol with a hydrometer, the used 100% alcohol from the processor was over 100% (which I have never seen before). I also checked a new bottle of alcohol and it also read over 100% so then I wondered if the hydrometer is calibrated only to a specific alcohol or if it has been damaged. So far our tissue seems to be processing fine but I would like to fix this before it becomes an issue. Thank you for any input, Maria Samaan _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
