ABSTRACT:
There are described a cuvette and a method for sealing off flow such as flow in a passageway from an access port in the cuvette with a closure, that ensures a complete seal merely by applying the closure. The cuvette is improved in that it has the closure in a closure portion that is joined to the rest of the cuvette along a hinge line that passes through the passageway to be closed off, so that application of the closure by bending the closure portion about the hinge line pinches off the passageway.
