If anyone happens to come back and see this video, an easy solution for the organics would be a quick piranha solution (concentrated sulfuric acid + hydrogen peroxide). It would've cleaned it up much faster than waiting for the sodium hydroxide. The more you know as you age!
I believe the ebay classifications of your test tube results would be: 2 items -"New, Unused (box missing), I just bought too many / Unwanted gift" 3 items -"Vintage, No Defects, Perfectly Functional!" 1 item -"broke in the mail, take it up with the post office"
I became a fan of using sodium hydrosulfite and sodium thiosulfate to remove some transition metal related stains. They seem to work on some other types of stains as well. Much of the other harder to clean stuff I just make piranha solution.
I find videos like this super useful and rare to find!everyone wants to see fires and explosions.just doesnt make sense to me,cause if all your glass isnt clean you cant do anything!great job thanks for sharing.
A sol’n of HCl & H2O2 will kill most metal salts & metals incl copper. For those really tough stains there’s piranha sol’n or just go straight to the nitric (10%) > 3 hrs. Your base bath needs to be more stout (10% or 4 M NaOH). Careful, it etches glass so 1 hr will do. That’s how I roll, good luck.
Hi there! I decided to make a poll to see which videos you might want to see first. I have all the options listed at the end of the video in the poll, so feel free to go ahead and vote: www.strawpoll.me/14744223. Thanks!
how do you I clean a large Pyrex demijohn with a white mineral scale? Unable to scrub effectively due to narrow neck. What about an abrasive with agitation?
You are using too many chemicals to clean test tubes. I just use a very strong solution of Sodium Hydroxide and then heat it in the test tube until boiling to clean all my testubes and glassware.

Pretty much calls for piranha solution to remove the organic remnants no?

Sir how to laboratory check the quality of toilet cleaner
Try hot acetone or mek on the hot glue. You could always try a heat gun on it instead of a torch
How do you dispose of the waste from the washings?
Happy new year bra...
Expecting great content as always.
Sodium Hypochlorite Happy New Year! Thank you for watching!

How about aqua regia?
