I purchased this magnetic stirrer to mix as well as create custom inks from pigments.

This works perfect for small jars of inks and also tiny vials (2-15ml) of ink as long as the ink isn't too thick. When working with inks that have mica pigments often the mica settles to the bottom rapidly meaning I need to mix my inks just before dipping my nibs to ensure that the pigments are mixed up, this stirrer is perfect for that. The stirrer is quiet and has adjustable speeds. Instead of using stirrer bars since my bottles are tiny, I actually purchased rust proof bbs meant for pellet guns that are just shy of 1/4 of an inch and they work great. Depending on my jar or vial size I put 2-5 bbs in the ink, if it doesn't start mixing at about 1/4 of the full speed on the dial, I add another until mixing starts. If the vial is too light I put tape around the vial to prevent it from moving.

There are actual ink mixers but are small, you could not use them for mixing larger batches, this stirrer does small to large batches and in some cases I can actually mix 2 small vials at one time.

Really happy with my purchase and I highly reccomend this stirrer for calligraphy inks.

Obviously this is an inexpensive stirrer and initially it did not work for me. I'm using it for beer yeast harvesting and with the slurry you cannot see what is going on. Initially I put my flask on it and fired it up to full speed but nothing looked to be working. I could not tell if it was not spinning or if the magnet got thrown off. After reading the instructions, I realized that you have to start real slow and gradually turn it up. By doing that it worked great for me. Now we'll see how long this thing lasts.

There simply isn’t anything negative that I could possibly say about this unit. It is fully adjustable from a light stir, to a full out oxygen incorporating cyclone to break up mycelium & spore clumps in your sterile jars.
I suggest that you buy a bunch of extra magnetic stir bars as this unit only comes with 1.

Perfect for making structured water at home.

I ordered this for my mycology hobby. It arrived as described and on time.

This is easy to use since it's literally plug and play. I appreciate the fact it came with one magnetic stirrer most of all.

I'm pleased with it and recommend it.
