In a sample holder (9) for decomposition or analysis of sample material by heating the sample material in a heating appliance (1) such as a microwave oven, comprising a receiving part (11) having a filling opening (15) for the sample material, a lid (14) to close the receiving part (11) and a valve (16) in the upper part of the sample holder (9) that comprises a valve seat and a valve member that bears, counter to its direction of closure, against an elastically yielding thrust piece (31), the cross-section of the thrust piece (31) in the plane running in the direction of closure of the valve (16) is shaped as a plate spring.
Claims17
A sample holder for decomposition or analysis of sample material in a heating appliance, said sample holder comprising a receiving part having an upper peripheral rim which defines a filling opening for receiving sample material and which also forms a valve seat, a lid which has a resistance to deformation and bending for closing the receiving part at the filling opening, a moveable valve member formed on one side of said lid, said valve member being configured to close on said valve seat and an elastically yielding thrust piece formed by a plate spring with a dome shaped body having flanks and which diverges to an outer peripheral rim, said thrust piece being positioned to press elastically against said lid on the side thereof opposite said valve seat.
