The LS 40 noise protection box is used to reduce the noise level generated when liquids are exposed to sound. The sound process can be observed through the large Plexiglas window in the robust door (1). The ultrasonic transducer is used both during direct sonication with sonotrodes and during indirect sonication using a cup resonator or sonication cup completely in the noise protection box with the help of a holding frame (e.g. HG 40). The sample vessels can be positioned directly in the collecting tray or on the perforated plate above. An anti-slip mat is included to prevent slipping and tipping. If necessary, adjustable recording tables (e.g. scissor table) can also be placed directly in the noise protection box. For flow-through sonication, external cooling or the use of a temperature sensor there is an opening (2) on the back of the noise protection box for hose or cable entry. On the right side there is a push button (3) for switching on the lighting and the ventilation systMeer tonenMinder tonen
