So based on @123456 excellent data above (Thanks!), for automated valves my notes show that a standard direct acting valve will not generally work with liquids over 50cP (like 50% cream). For anything over 600 cP (like SAE 30 oil) you want to use a coaxial valve or air operated angle seat piston valve.

Dang, those terps really seem to thicken things up.

27

If I can ask, what viscometer are you using?

28

NO they donā€™t!!

they are clearly reducing the viscosity!!!

15% lowers viscosity at 10C to that of 5% at 30C

5% lowers viscosity at 30C by 50%

makes sense with terps being a solvent in their own right.

30

evolved by the plant explicitly to solubilize the cannabinoids some would argueā€¦

this interesting little thread didnā€™t get much attention

anyone integrated viscometers into their workflow that would care to share anything?

Iā€™m mostly looking at capillary viscometers and ball drop tests, Iā€™d be interested in any feedback on rotational viscometers/rheometers/rheosense equipment as well

This might be the best post on the forum right here.

Gold!

I have been thinking about getting one for awhile, my plan is to measure different batches of HTE to determine viscosity before filling carts to make sure they wont clog

Thatā€™s the application I was thinking of

You can measure your raw distillate/decarbed THCa, then each batch of HTE. Would give you an idea whether or not youā€™d benefit from distilling part of the hte and reintroducing the terps, or just what ratio of terps/HTE:disty flows best for any given cart

I was told about this forum through a customer of mine. If anyone has any questions about RheoSense viscometers for cannabis use please DM me. I am one of the Reps.

What units go above 100,000 cps?

38

Usually for measuring the flow of very thick, bordering on solid things, a Rheometer is used.

Centipoise is equivalent to millipascal seconds. Most of us use centipoise and in the industry, Poise is very rarely used. Our viscometers can test up to 300,000cP and measure with 100uL of sample volume. More questions welcome. I have application notes on cannabis oils as well if anyone is interested message or email me dfox@rheosense.com

You seem like a nerd that is just going to measure it yourself anyways.
