Abstract
A vial assembly integrates the functions of drawing up of a liquid sample through an inlet tube into a storage chamber (a vial), sealing the inlet tube, severing the inlet tube below the seal, identifying the sample for later analysis, and providing sample extraction. Liquid is drawn into the chamber by expanding a collapsed bellows inside the chamber, thereby producing a partial vacuum which draws liquid through the attached inlet tube into the storage chamber. A hot knife sealing shear is then activated to sever the end of the inlet tube from the storage chamber, while simultaneously closing and melting shut the chamber side of the tube. A unique bar code label is on each vial for sample identification.
