[Histonet] VIP issue

[Gudrun Lang]

Dear all!

I have a question for those, who are familiar with the VIPs from Sakura. 

Last time we changed the reagenses the cleaning-ethanol (96%) was very milky
and even was full of many small particles. It was a paraffin-soup.

What is the cause for such a case?  We have been using the organic solvent
(ShellSol) for decades as xylensubstitute. 

Maybe the quality has suffered and the ability of solving paraffin has
decreased. But are there other explanations? Maybe a malfunction of the
instrument?

 

Thanks in advance
