Abstract
A sample ejection device for pipetting or dispensing very small quantities comprises a sample ejection head (10). The sample ejection head (10) is provided with a plurality of pipettes (12), a plurality of micropumps (46) for conveying very small quantities, and at least one storage container (24) connected with the pipettes (12). The sample ejection device further comprises a control unit (26) for controlling the sample ejection head (10) and a monitoring unit (28) for monitoring the sample ejection head (10). For facilitating exchange of storage containers (24) or pipettes (12) the sample ejection head (10) is exchangeable as a whole. It is thus not necessary to exchange individual storage containers (24) or individual pipettes (12) during a pipetting process. Exchange of the entire sample ejection head (10) can thus be effected considerably more quickly.
