The VialTweeter enables for the simultaneous sonication of up to 10 vials at the same intensity. Thereby, the VialTweeter is a reliable lab homogenizer for homogenization, emulsification, dispersing and deagglomeration, extraction, lysis, dissolve, as well as the degassing of fluids. Due to the principle of indirect sonication, no probe is immersed into the sample so that cross-contamination and sample loss is completely avoided.
