I'm using the all famous Alconox powder detergent to clean my laboratory glassware, the powder is a pain to store near the sink and to use. Would like to make a more friendly concentrated liquid to use in its stead. They sell "Liqui-Nox" which I assume is Alconox in liquid form . . and it's twice the price.

I have tried a few things, obviously just water and mixing, even up to overnight. It really doesn't go into solution very well, even at seemingly low concentrations. Ive got it up to about 20% w/v but I've tried heat, glycerin, adjusting pH to ~8.8, adding EDTA. I have not added these things in any scientific way, just kind of pouring glycerol or EDTA in.

Wondering if anyone in here has experience with detergents like this , or has done something like this before. Thanks in advance!

for usual cleaning a regular liquid detergent should be sufficient. I subsequently wash it thoroughly with milliQ water. Unless you are doing some sensitive experiments such as mass spectrometry, the minute amounts of residual detergent should not be a problem. For what purpose do you use Alconox ? –  WYSIWYG Apr 22 at 5:03
Obsessive compulsive disorder mostly. I like having clean glassware. I pulled up msds on alconox and liquinox. They are very different chemicals. Would have been nice to be able to make a viscous concentrated liquinox out of all the powder alconox we have though. –  rhill45 Apr 22 at 5:08
