Claim:
1. A sample application valve for an apparatus for synthesis, analysis and/or separation purposes, the valve having at least three liquid connectors, having a housing as a valve part, and having a valve body as another valve part, for optional connection of the liquid connectors by way of at least one flow channel delimited at least in part by sealing surfaces between housing and valve body, wherein housing and/or valve body are mounted so as to be movable relative to one another, wherein at least one valve part that borders on the sealing surfaces and has a plastic material is configured to be plastically deformable, as a function of a relative position of the valve body, in order to be able to withstand increased pressure stresses in the flow channel, in liquid-tight manner, in this relative position of the valve body, wherein in this relative position the at least one valve part plastically deforms irreversibly to withstand the increased pressure stress in the flow channel.
