Schoonmaken van laboratoriumglaswerk

[malayboy]

Hallo meneer, ik heb de "Alconox"-producten bekeken en het blijkt dat ze een productlijn hebben voor laboratoriumtoepassingen. Is het goed als ik al hun producten gebruik, zoals Citranox, Alconox, Liquinox en Tergazyme, in plaats van mijn eigen wasoplossing te maken zoals u voorstelt, een mengsel van sulfochroom, kaliumpermanganaat en alkali-alcohol?

omdat ik me in mijn situatie zorgen maak over het afval dat ik afwas of weggooi en dat de ondergrond van de gootsteen zou aantasten, toen zag ik het product van alconox, ze beweerden dat het de gootsteen niet zou aantasten en dat spoelen gratis was.

My friend used alcanox, and swore but it. He used it to clean stainless and glass, and used an ultrasonic cleanser to clean it in

ok bedankt, ik zal het proberen met alkali/ethanol en kaliumpermanganaat, neem een experiment.

REALLY GREAT ARTICLE !!! I was actually trying to find a post about cleaning glassware from a laboratory and was about to make a new post until I found this one ! Great post !

What is the best way to clean the inside of a flask?
If you don’t have a bottle brush, the best way to clean the inside of a flask is by creating friction by using rice, salt or bicarbonate of soda. As we shared in this article, you can pour rice into the flask and fill half of it with cold water. Close the flask then shake it for a few minutes. You can use the same process with salt and bicarbonate of soda.

Or
Bottle brush or a cleaning cloth with hot water

Or a round-bottom flask brush

Question

In the attached picture... After distilling safrole from sassafras oil, the RXN glassware appears really dirty (burnt organics?)

How would swim go about cleaning the glassware clean so swim could use the same glassware again next time ???

 

[G.Patton]

H2SO4 c + K2Cr2O7 mixture or KMnO4 + org acid will clean it up

 

[Chemtrail]

Swim doesnt have that

Swim does have sodium hydroxide and ethanol

Would a base bath do ??

Alkali alcohol solution.​

The alcohol-hydroxide cleanser is used to clean glass. It is an effective cleaner.

*To clean the above picture

 

[G.Patton]

Try and check. What a problem?

 

[Chemtrail]

What "cleaning brush" do you recommend??

SWIM DOESN'T WANT A BRUSH THAT WOULD SCRATCH THE INNER GLASS WALLS !!!

Plus the brush needs to be able to curve as so to clean a round bottom flask

?

Different combinations of strong oxidizing acids. "Piranha solution" - Concentrated H2SO4 "liquid fire" drain cleaner and %3 H2O2 hydrogen peroxide solution from the pharmacy. Add equal parts (not too much!) and swirl in the glass piece you want cleaned. Definitely wear gloves and goggles and all that other crap, you don't want to mess with this stuff!

You can make all different kinds of these solutions for cleaning purposes, if you don't have one reagent, try another. Double check to make sure that you aren't going to make any poison or explosive gas.
