I have tried out a new setup for concentrating peroxide. I don't really like talking about peroxide concentration because it is quite hazardous, but suffice in to say it was quite successful. I have now reached the limit of what I can achieve using my current method (about %84.5), and I am able to produce a large batch in a time frame I am happy with. I am concerned that the large concentration of stabilisers might affect the density, so I would like to try a volumetric approach to calculate concentration.
