The invention concerns a device for cleaning pipette needles or stirrers, the device comprising a trough which holds cleaning fluid and whose lower region has a fluid duct for filling and/or emptying purposes and whose upper region has at least one feed pipe which leads into at least one nozzle directed into the trough interior. Advantageously, the device has a cylindrical trough and an insert with nozzles which is screwed into the trough. The invention further concerns a method of cleaning pipette needles or stirrers, the material to be washed being introduced into the trough interior and sprayed with a washing fluid. The device can also be used to flush the interior of a pipette needle.
