Thermocycler

Abstract

A thermocycler having a base fitted with a temperature-controlled receiving segment for reaction vials is provided. The thermocycler further includes a top, which can be moved into its operational position above the receiving segment and a hermetic seal or wall configured in the top in its operational position that extends between the top and the base thereby sealing both the top and the base.

1 . A thermocycler comprising:
 a base fitted with a temperature-controlled receiving segment for reaction vials;   a top which can be moved into an operational position above the receiving segment; and   a hermetic wall configured in the operational position of the top to surround the receiving segment while extending between the top and the base thereby sealing the top and the base.   
   
   
       2 . The thermocycler as claimed in  claim 1 , wherein a test optics is opposite the receiving segment when the top is in its operational position. 
   
   
       3 . The thermocycler as claimed in  claim 1 , wherein the hermetic wall is light-tight. 
   
   
       4 . The thermocycler as claimed in  claim 1 , wherein the hermetic wall is adjustable in length. 
   
   
       5 . The thermocycler as claimed in  claim 1 , wherein the hermetic wall is mounted by its upper open end to the top. 
   
   
       6 . The thermocycler as claimed in  claim 1 , wherein the top is fitted with a setting element to allow adjustment to the length of the hermetic wall. 
   
   
       7 . The thermocycler as claimed in  claim 1 , wherein the hermetic wall is a bellows. 
   
   
       8 . The thermocycler as claimed in  claim 1 , wherein one or more closed loop seals are constituted at the free end of the hermetic wall.
