I would like to know about the experiences and views about different ultrasonic processors used by various researchers for nanofluid sonication. There are many ultrasonic processors available in the market but i am not sure how to pick one and i don't want to take a chance by randomly buying one since they are very expensive and the money is funded by the state.
So i will be extremely grateful if someone can share his/her experiences or recommend me the name of a good ultrasonic processor making company!
Thank you very much!
