Abstract: A pipet gun for drawing liquids into and dispensing liquids from a pipet which includes a variable flow valve assembly. The valve assembly includes a valve which is capable of accommodating a plurality of flow rates, and which is progressively adjustable during pipetting between a first air flow rate and a second air flow rate which is in excess of the first flow rate and which is non-progressively adjustable during pipetting to a third air flow rate which is substantially greater than the second air flow rate. The valve assembly further includes a threshold detector in the form of a spring detent, which provides an indication to the operator that the pipet gun is operating at the increased fluid rate, i.e., the “express mode” of operation.

Abstract: The present invention is an additive preparation for use in bodily fluid collection devices. The additive preparation has an additive, an organic acid and a metal carbonate compound. The preparation effervesces when in contact with a body fluid sample, thereby efficiently dispersing in a body fluid sample. The formulation is desirably tabulated to provide an effective, easily stored, and handled preparation. However, a binding or bulking agent may be added to the additive preparation formulation to provide binding and lubricating properties to the formulation. A binding agent enables granulating of the formulation without the forming of a pellet.
Abstract: The present invention is a collection container assembly comprising a container having a wall space between the inner and outer wall of said tube whereby the external dimensions of the container are substantially the same as a standard-sized blood collection tube but with a reduced internal volume.
Abstract: The present invention is a collection container assembly comprising a container having an inert plug inside the bottom end of the container and wherein the external dimensions of the container are substantially the same as a standard-sized blood collection tube but with a reduced internal volume.
