1. A closure device for closing a particle capture volume, comprising:
an access element with an access element opening for providing an access to the particle capture volume,
a closure slide which is selectively displaceable relative to the access element into a release position or into a closure position, wherein in the release position the closure slide releases the access element opening and in the closure position closes the access element opening, and
a locking mechanism for locking the closure slide in the closure position with respect to the access element, wherein, for unlocking, the locking mechanism requires an unlocking element separate from the locking mechanism,
wherein the closure device further comprises the unlocking element,
wherein the closure device further comprises a blocking mechanism which in the release position of the closure slide prevents a displacing of the closure slide relative to the access element in the direction away from the closure position.
