Method for checking the state of a pipette, pipetting method, pipetting device, and suction tube for a pipetting device |
摘要 |
The invention relates to a method for checking the state of a pipette, which pipette includes a suction tube and a pipette tip. According to the invention, ultrasound is coupled into the wall of the suction tube and the damping of the ultrasonic signal is measured as a function of the frequency. The measured frequency-dependent damping is compared with at least one reference measurement or a calibration curve based on the reference measurements, in order to determine whether the pipette is in a functional condition and/or whether the pipette contains or has made contact with fluid. Furthermore, the invention relates to a pipetting method which uses the inventive method for checking the state, a suction tube arrangement for a pipetting device for pipetting fluid, and a pipetting device with which the inventive methods can be carried out. |
