High Shear Mixer
Hello,
Am looking into buying a high shear mixer for making my emulsions. However they tend to be around £600 up to £4000. I found some on Amazon UK and Alibaba/Ali-express/DHS, however am not sure whether I should go for them, as they are very expensive and can’t guarantee their quality if the sellers are from China. I have had bad experience with buying equipment from China.
Are you aware of any secondhand sites that sell lab equipment, and specifically high shear mixers? Because I found some sites, but they tend to sell factory size secondhand equipment. My budget for this is £750 max.
Thank you,

OMG I just got one, again from China. They always deliver something that works at least. However, I just bought a high shear mixer (no label of course) and its a beauty. This was from ebay, I got it for about $250 Aussie

Sorry the only thing is once again, the instructions are in chinese and it was in about 40 parts. That was the only downfall. Who needs instructions anyway! my dad didn’t…

That’s very expensive £600 you can buy second hand one for that price of good brand
I’m guessing this is a lab one?
-
There are auction websites, Ive even seen silverson second hand with all the parts for £800
I understand this is not homogenizer, but this is a used auction website ; but let me tell you, eBay auctions are always cheaper!

that’s just a stirrer and not a homogenizer - i would rather DIY a stirrer

@VitalikButerin thanks, what are differences between stirrer & homogenizer?
-
Stirrer just stirs.
Homogenizers like emulsifyers aim to combine the two difference molecules into one mixture. Like powders and oils, it really breaks them down a lot more whilst spinning them, not only just by stirring them
-
Instead of starting another thread to ask this question I could as well shoot here.
Is there any noticeable difference between lotion made with high sheer mixer and one made with a stick blender? Please I really need to know before I could consider investing in a high sheer mixer.
-
It depends on the stick blender. Some can produce high shear. Many don’t.

I have question:
1) all ingredients that are water soluble are mixed well with stirrer
2) all ingredients that are oil soluble are mixed well with stirrer.Now 1) and 2) are put together for emulsion
Question: should I use stirrer or homogenizer?thanks in advance

@Ellatorias, I managed to make water in oil and water in silicone with a stick blender although some say it’s impossible. It depends on a stick blender. Get yourself Bosch with two heads.
