A device configured for lysing a sample includes a holding element configured to hold an energy-transmitting element such that the holding element lies around the held part of the energy-transmitting element and envelops the held part of the energy-transmitting element and/or that the holding element lies against the held part of the energy-transmitting element. The holding element is further configured to cause lysis with the energy-transmitting element when the holding element is immersed into the sample to be subjected to lysis or comes into contact with the sample to be subjected to lysis. A method includes inserting the energy-transmitting element into the holding element. A system configured for lysing a sample by way of ultrasound includes the device and the energy transmitting element.
