ABSTRACT:
The invention relates to a thermocycler apparatus for implementing chemical and/or biological reactions and a method for activating the thermocycler apparatus. The thermocycler apparatus in accordance with the invention comprises a basebody in which for accommodating one or more reaction vessels open at the top an accommodating portion is configured. For closing off the accommodating portion of the basebody a cover is provided. Spring elements are arranged on the thermocycler apparatus such that the cover and the reaction vessel(s) are urged together and the reaction vessels are closed off directly by the cover or by means of an interlayer.
The invention is characterized by an electrochemical linear motor arranged such that the cover and the reaction vessel(s) are urged together by a pressure higher than that produced by the spring.
Providing the linear motor enables the additional compressive force to be exerted independently of the closing action of the cover and permits the compressive force to be freely varied and precisely defined.
