Help Me Clean My Flask

[DrWHY420]

Im trying to clean my boiling flask. There is a thin red film from my waste material boiling onto the sides. I have tried alcohol, acetone, papertowels on scrubbing brushes, soap and water, and now I am trying citric acid which doesnt seem to be helping. What should I do to remove these stains from my glass?

[PolyC]

stupid question but i have to ask

are you sure that those stains aren’t inside your heating mantle?

[DrWHY420]

Yeah, should have uploaded this too

just replying so I can track this thread because I am also curious

Base bath. Be careful though.

It’s not exactly the same, but when I couldn’t get the stains off my wiper evaporator, I used to soak it in limonene.

AlcoJet might work too, it’s really basic though so be careful, like @NewLevelProcess says.

[PCGextraction]

acetone works well

Acetone has been tried

this one has come up a couple or ten times…and there are some great solutions (including piranha) offered.

If you haven’t explored them all, I highly () recommend doing so.

@MagisterChemist

Aqua regia is one thing, great for inorganic contaminants and quite good for organics. But if you want ultimate cleanliness from organic contaminants, you want what’s called piranha solution – h2s04 and 30% hydrogen peroxide. It fits the name and has fascinating chemistry such as the production of atomic oxygen as active cleaning agent.

Works wonders

[ZizzleB]

that’s the one I was looking for.
I remember it from another thread but could not remember the name for the life of me.

thank you!

[SubstituteCreature]

No worries at all my friend

[PolyC]

Soak it in a base bath (8M NaOH) or acid bath (70% nitric acid) in a fumehood. Leave it overnight. Rinse with several volumes of water. Then try your organic solvents again.

Do you have access to a sonicator? Usually helps with stubborn grime on our parts.

[DrWHY420]

No I sold it using @RuderEquipment

AlcoJet might work too,

Alconox. Alcojet is the low foam version for use in dishwashers.

I use a bunch of quartz or stainless beads to help when I’m scrubbing a nasty residue off.

[Dannywarbucks]

Yeah, I was thinking another alconox product, Keylajet. I’ve used keylajet before but it’s very basic

[SubstituteCreature]

That sounds like a direct ketamine delivery system
