Use a syringe much more accurateI use a pyrex 25 mL graduated cylinder left over from undergraduate chemistry to measure stock (from the Kodak bottle) HC110. It takes a while for it to run run down to the bottom in order to get a proper measurement. That has remained consistent over time (decades). Somewhere between honey and maple syrup (the real stuff that now comes in small plastic jugs).
I use a 50 ml graduated cylinder similar to the one that Focomatter uses, but I use it in a different way.
I put something like 20 ml or 30 ml of water in it. I then slowly add the syrup to the water, making sure that the syrup doesn't contact the side of the cylinder above the water. I watch the level of the water rise until it reaches my target total - from 30 ml to 36 ml, if I am trying to add 6 ml.
I then rinse the graduated cylinder thoroughly into my final measuring graduate, and then top it up to the final volume.
Does anyone have experience of using HC-110 as a print developer?
I remember people reporting a thinner consistency of HC-110 after Kodak changed the manufacturer. If your bottle says "Made in Germany" then it is the new stuff and was most likely produced by Tetenal (as mshchem noted). This change doesn't seem to affect development times or results in any way.
Because if there is no water, the viscose HC-110 sticks to the side of the graduated cylinder and it is much more difficult to measure.Question:
Why don't you just add the HC-110 first?
Then you can rinse and have all kinds of fun,
and fill up with water, to your target level.

I believe Covington's webpage addresses the two configurations (domestic vs European) of HC-110 when Kodak was manufacturing the product and doesn't address the current product produced by Tetenal. Tetenal has been manufacturing HC-110 in Germany since Kodak folded its tent and farmed out its products.Michael A. Covington's website http://www.covingtoninnovations.com/hc110/index.html explains the difference between the US and the European versions of HC-110. Mr. Covington writes:
Note: In Europe, HC-110 is also sold in 500-mL bottles as a less concentrated syrup which you dilute 1:9 to make dilution B. If you are using that product (Kodak CAT 500 1466), follow the instructions for the European concentrate, not those for the syrup. Although the European type of HC-110 is sold in England, there does not seem to be an English data sheet for it. Full-strength syrup is also sold in Europe so make sure you know which one you have.
You will also find dilution guidelines for the two versions in this article.
Conclusion: I believe the formula was adjusted when Tetenal assumed production and even though they claim development times should be the same, the resultant negs do not reach the same densities as the original formula when comparing negs in my files using both developers. If you search the web, you will find others have made the same observation.

The meniscus created by a mixture of a relatively small amount of syrup in a larger amount of water is very consistent and easy to read against the graduations in the cylinder. The meniscus created by a 6 ml (for example) quantity of the syrup - not so easy to read against the graduations in the cylinder.

That works fine if the two liquids add volumetrically. Some don’t. An example is water and ethanol, which, when mixed result in 10% less volume than the volume of the two constituents.
Whether this is a factor when mixing HC-110 I don’t know, but it might be.
