Device suitable to withdraw and distribute automatically analitical samples into plates containing culture media for microbiology.

摘要

The proposed device allows to perform all operations concerning the microbiological analysis automatically without intervention of the operator and in particular : - collection and withdrawal of samples; - distribution of material into the Petri plates containing the culture media; - sterilisation of the loop used to withdraw and distribute the samples. This is obtained by the device composed by : - means to collect, withdraw and distribute the samples to be analysed including the device for the direct contact with the samples; - means for positioning the samples; - means for positioning the plates; - means for opening the plates and for their successive closing; - means to position the plates; - means to allow the motion of the above-mentioned means; - means to provide the sterilisation of the device which is in contact with the samples; - means to control all operations and interface with operator.
