Probe diameter and amplitude
A small tip concentrates energy in a small volume; a large tip spreads it thinner. Ask the amplitude for each probe offered.
No DramaBuyer guide · Lab & process
An ultrasonic homogenizer is sold by watts, but the energy reaching your liquid depends on tip, amplitude and volume, so a beaker result does not scale to a tank with a bigger generator.

01
A small tip concentrates energy in a small volume; a large tip spreads it thinner. Ask the amplitude for each probe offered.
A flow cell treats liquid pumped past the tip, for continuous work. Non-contact units treat sealed tubes.
Cavitation erodes the tip. Ask whether tips are replaceable and their price.
Sonication heats the liquid. Ask for pulse mode and a temperature cut-off.
It is loud. Ask whether a sound box fits your vessel.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

|---|---|
| Treat your sample at the offered settings and measure particle or droplet size before and after. | Size reaches your target, repeated on three separate batches. |
| Log sample temperature through the whole run. | Temperature stays below your limit throughout the run. |
| Inspect the tip before and after a long run on your product. | Tip wear within what the supplier states, with no metal flakes in the sample. |

A high shear homogenizer or a vacuum emulsifying mixer; three listings under this name were exactly that.
A planetary mixer, which moves viscous mass that ultrasound cannot circulate.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.
07
Every machine we source in this area is on the Lab & process page. How a project runs, stage by stage, is on how it works, and what it costs is on pricing.
Straight answers
One whose probe, amplitude and cooling match your volume, proven on your sample.
Compare tip amplitude, tip life and repeat results on your sample, not watts.
Probe set and spare tips, amplitude per probe, temperature cut-off, enclosure, and measured results on your sample.
Your business when you buy from outside the EU. You check the declaration matches the unit and add your name.
