An apparatus for the precise transfer of liquid droplets (so-called ‘liquid handler’) measuring approximately 540 × 680 × 930 mm and weighing approximately 128 kg. The apparatus consists of two devices for receiving microplates (source plate and destination plate), two deionisation rods and an ultrasound head incorporated in a compact housing with a control LED, a small display and an emergency button. The apparatus utilises the Acoustic Droplet Ejection (ADE) method which uses sound energy (targeted ultrasonic pulses) to move ultralow volume of droplets of liquid from a source plate to an inverted destination plate with extremely high precision and accuracy. The system transfers droplets of 2,5 nano-litres per ejection enabling the transfer of larger volumes of liquid. Multiple droplets are ejected from the source at up to 500 times per second. The apparatus is used in the preparation of samples in laboratory sites to transfer specific volumes of reagents from one microplate to another.
