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.
