摘要： A chromatography column apparatus which utilizes sorbant material in a tube which has a first and second end portion. The first end portion of the tube includes a plug having a passage through the same. The plug fits in the same, adjacent the sorbant material, and is movable within the tube. An end fitting is also employed which has a portion that is placed within the tube adjacent the plug. The end fitting has a passage therethrough which communicates with the passage of the plug. A seal is used inside the tube between the plug and the end fitting. The end fitting and plug are held together. The second end portion of the tube is enclosed and also includes a passage from the interior to the exterior of the tube.

摘要： A sample injection valve using a member having four ports as a fluid system inlet, a sample injection inlet, a fluid system outlet, and a vent. The valve also uses a fluid sample reservoir and includes a controller for simultaneously connecting the fluid system inlet and outlet and interposing the fluid reservoir between the sample injection inlet and the vent. A switch changes the position of the fluid reservoir to one of interposition between the fluid system inlet and the fluid system outlet.

An end fitting is also employed adjacent the plug. The end fitting has a passage therethrough which communicates with the passage of the plug. A seal is used inside the tube between the tube and the end fitting. The second end portion of the tube is enclosed and also includes a passage from the interior to the exterior of the tube. A manually actuable gear mechanism is incorporated in the end fitting of the first end portion of the tube for facilitating application of axial force to the packing material, thereby compressing the packing material so as to eliminate voids and channels in the packing material. Other features are also disclosed.

摘要： A hand-held manually operated pipette having an adjustable plunger stroke and calibrated electronic digital volumetric display draws-up and dispenses viscous, dense or high vapor pressure liquids by means of an easily replaced, disposable, integral, positive displacement type plunger tip and capillary assembly. The pipette in another form utilizes a disposable air displacement capillary. The plunger adjustably strokes to a first stop in a first mode for calibration or sample draw-up and dispensing with the volume of pipette liquid contents continuously displayed. In a second mode an over-travel arrangement enables the plunger shaft to stroke beyond the first stop to permit collet type attachment and ejection of the integral plunger tip and capillary for positive displacement service or to eject an air displacement capillary.

摘要： A needle injection device for delivering fluid through an opening in a body utilizing a pair of bushings placed substantially in end-to-end orientation. A filter is placed adjacent one of the bushings generally within the opening. The bushing nearest the filter is constructed of sealing material such that forcing of the first bushing against the second bushing seals the area between the needle and the sides of the opening immediately above the filter.
