Is the cannula for drug pipetting disposable?
No. There is no need to change it, because the Teflon-coated cannula will be completely washed out between different compound applications. The washing of the cannula is achieved by a continuous flow of washing solutions that are delivered from the back of the device to the tip, just like it is common in many industrial standard pipetting robots. In addition, washing of the cannula is assisted by ultrasonic vibration. However, if a new drug cannula is necessary for any reason, the cannula and the corresponding tube can be quickly and easily exchanged.
