Claim 1:
2. A system comprising:
a first closure device for closing a first particle capture volume, the first closure device comprising a first access element with a first access element opening for providing an access to the first particle capture volume,
a first closure slide which is selectively displaceable relative to the first access element into a release position or into a closure position, wherein in the release position the first closure slide releases the first access element opening and in the closure position closes the first access element opening,
a locking mechanism for locking the first closure slide in the closure position with respect to the first access element, and
an unlocking element separate from the locking mechanism,
wherein, the locking mechanism requires the unlocking element for unlocking,
wherein the unlocking element is attached to the first closure slide,
the system further comprising a second closure device with a second access element which comprises a second access element opening which provides an access to a second particle capture volume, and with a second closure slide which is attached to the unlocking element and with which the second access element opening can be closed.
