Stop bath 60% ADOX Acetic Acid 500 ml
Can be used as a universal stop bath. Acetic acid, chemically pure, 60% conc.
Industry-standard, usable also for synthesis. Acetic acid lasts longer as a stop bath than citric acid. But it smells and the concentrate even "bites your nose".
If diluted to 2% or 3% everything is fine and the workhose can stop many sheets of paper.
Becasue of the fact that this is a chemical base compound the applied VAT is only 7%.
