Old-fashioned Glass Distiller

Hello,

We have one of those old-fashioned glass distillers in our lab to provide distilled water (the one that looks like a big round-bottom flask). It's getting a bit grubby now, and I wondered if anyone knows what cleaning procedure(s) are used to get the gunk out? Thanks in advance for any replies.

Or use chromerge nasty stuff tho hexavalent chrome & sufuric acid recipe is in many Chem books or just google "Chromerge"

Forget the Chromerge. It is

Forget the Chromerge. It is too toxic and difficult to dispose of.

Hell ,

You may clean it with sulphanilic acid or else conc, sulphuric acid followed by water and finally with sandoclean to get good shine

Soak the glassware an acid

Soak the glassware an acid bath (HCl is easiest) for several hours or overnight. If everything hasn't dissolved move it to a base bath (NaOH) for a similar period of time. Soak the glassware in Distilled water overnight as a last step.

If you use the base bath you will need to soak the glassware in the acid bath for a couple of hours before rinsing it and moving it to the water bath.

Hi all I am new member here and I am here to share my views on distilled water. Actually few months back I fell ill and after my check up the reports showed that it is because of the dirty water which i am continuously drinking. After that I thought that the water coming in my home in the taps was not actually pure. I realized the importance of clean water in our daily life and then i switched to a product names water distiller. This product is really amazing and now I am 100% sure that the water I am drinking is extremely clean. Thanks to this amazing product and I can see the improvement in my health also.
