The performance of our recently developed non-contact mixing device was evaluated by using a serum and a reagent as a test liquid. The non-contact mixing device can mix the liquid-without actually making contact with the liquid itself-by ultrasound irradiated from a sound source installed out-side of the vessel containing the liquid. The present study shows that a mixture of the serum and the reagent can be visualized by the Schlieren imaging method, which uses the difference in their refractive indexes. The gray-scale data from the Schlieren images obtained before and after mixing were used to evaluate the performance of the mixing device. Moreover, under the condition that the dilution of the serum is a parameter, the mixing performance was evaluated in laboratory trials. The trial results show that a highly diluted serum (i.e., twice as diluted as a standard serum) can be mixed with the new non-contact mixing device.
