Abstract
A process for sampling and diluting a liquid to be diluted utilizing a device comprising a hollow tubular body and a sealed pre-evacuated container. The hollow tubular body includes a self-filling tube for drawing up and capturing by capillary attraction a predetermined volume of a liquid to be diluted. Additionally, the hollow tubular body includes a connecting tube in an air-tight sealing relationship with the self-filling tube. In a preferred embodiment, the container has a frangible tip for mutually interengaging in an air-tight sealing relationship with the connecting tube.
