Abstract: The present invention relates to an apparatus and a method for automatically performing chemical, biochemical and biological analyses using the apparatus. The apparatus comprises: a plurality of subsystems for each performing different operations on microtiter plates; a transporting subsystem for automated movement of microtiter plates in three directions X, Y and Z in order to transport plates from one subsystem to another subsystem within the apparatus; a liquid handler comprising at least two liquid handling probes, wherein said liquid handler is integrated in the transporting subsystem; an insertion/removal subsystem for inserting, removing and storing microtiter plates and equipment for sampling and dilution operations, wherein said insertion/removal subsystem is mechanically operated, without the need for electrical components implemented in that subsystem.

Abstract: The invention concerns a container 1 with chambers 2 which each comprise at least one pair of electrodes including a first 4 and a second electrode 5 for the application of electric voltage for generating an electric field within one chamber 2. At least two first electrodes 4 of different chambers 3 are conductively coupled and at least one second electrode 5 of said chamber 2 is separately conductively connectable. The invention further concerns a method for manufacturing said container 1 as well as a device for electrically contacting at least one of said containers 1.

Abstract: Disclosed is a method for treating biological material via electrical current, in which the biological material is added to a small volume of a buffer solution having relative high ionic strength. A strong electrical field is generated in the buffer solution by a high voltage pulse having a preset duration. The biological material is added to at most 50 ?l of a buffer solution with an ionic strength of at least 100 mmol/l. By at least one voltage pulse having a preset duration of at least 10 ?s, an electrical field with a field strength of at least 1 kV/cm is generated in the buffer solution. The voltage pulse is hereby interrupted at least once for a duration of at least 100 ?s and is then again continued.

Abstract: The invention relates to a container 20, 30 for receiving an aqueous solution, which is formed at least partially by an outer limit 21 forming an inner chamber 22, 32 for receiving the solution, and which comprises at least one area which acts as an electrode 25, 26, 33, 34 when an electric voltage is applied and a subsequent discharge occurs, wherein at least one electrode 25, 26, 33, 34 is made of a conductive synthetic material at least based on a plastic material which is doped with at least one conductive substance. A container 20, 30 of the above-mentioned kind is created this way, which is simple and economical to produce and also, for example, enables an efficient transfection of living cells by means of electroporation or an effective electrofusion.
