Abstract
A sample collection tube is disclosed for collecting a body fluid sample. The tube includes a closure arranged at an open end to close the open end and a partially evacuated inner space. The closure also includes a base portion connected to the sidewall and a cap portion coupled to the base portion, where the cap portion has an elastomeric material that is pierceable from outside of the tube for collecting a sample into the partially evacuated inner space and where the cap portion can be pivotable with respect to the sidewall such as to make the inner space accessible for withdrawing an aliquot of the sample. Alternatively, the cap portion can be separable from the base portion to make the inner space accessible and the base portion can include a self-resealable valve adapted to allow access of a pipetting unit into the inner space when the cap portion is separated and adapted to re-seal after withdrawal of the pipetting unit. Also disclosed is a work cell for handling sample collection tubes.
