Hi !
I've problems taming this product. It seems I can't get consistent results mainly because of inconsistent dilution.
This week, I've met a chemist working in a lab with high viscosity liquids. I asked him a question about a proper way to mix HC110 syrup consistently into, say, dilution B. He told me that measuring syrups by volume is quite impossible to do acuratelly. He told me to WHEIGHT the concentrate for mixing it up. So simple I've not even thought about this.
So, anyone knows for sure the density of HC 110 syrup ? Or am I obliged to devise it myself ?
Thanks for your help !

I can't answer your question, but I can make a suggestion. I used to measure HC110 fairly consistently using a glass syringe, the kind that are used for animal husbandry. Slowly pull in a few more cc's than you need. Put the needle up. Tap until all bubbles are in the top. Squeeze out the air. Push out extra solution. If you do this for the recommended amount, you could always then weigh this, or weigh the syringe empty and with the syrup in. You'd then have a good idea of the weight of the proper amount of solution. It'd also be an easy way of weighing, i.e. weigh the syringe. This would be a fairly non-messy way of doing it.
Thanks Peter, but this is the way I'll do it except that the sirynge is plastic. Maybe I'm too sloppy ?
And I'vee seen that density translate in English as "specific gravity"... When a tongue is not your's mother's one....
