The cup horn turns the QS4 system into a high intensity ultrasonic water bath. Cooling water can either be static, or can be flowed through the cup during sonication of your samples. Samples can be placed in sealed tubes or vials, and immersed in the bath. This is useful for samples that are temperature sensitive. The bath construction is acrylic, and has a 5.5” inner diameter. Within is a 2.5” diameter titanium probe tip.
