摘要： A multichannel air-displacement pipette liquid-end assembly having a modular construction, which enables individual components to be easily replaced when they become contaminated or worn. The modular liquid-end assembly also enables selected piston and cylinder components to be selectively removed so that any one of a number of predetermined multichannel pipetting configurations can be employed. Additionally, the modular liquid-end assembly preferably comprises an ejector for providing low-friction mechanical advantage in order to facilitate dislodging spent tips.

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 volume adjustable pipette, comprising a plunger mounted for movement in a housing to and from a stop to aspirate a fluid into and dispense the fluid from a tip extending from the housing. An axially moveable volume setting member in the housing defines the stop and a volume setting for the pipette and is axially moveable by a user turnable volume setting member. Turning of the volume adjusting member also controls a coarse volume setting means and a fine volume setting means, the course volume setting means being responsive to a relatively small turning of the volume adjusting member for moving the volume setting member a relatively large axial distance and the fine volume setting means being responsive to a relatively large turning of the volume adjusting member for moving the volume setting member a relatively small axial distance.
摘要翻译：一种体积可调移液管，包括柱塞，所述柱塞安装成用于在壳体内和从止动件移动以将流体吸入并从从壳体延伸的尖端分配流体。壳体中的可轴向移动的体积调节构件限定止动件和移液管的体积设定，并且可由用户可转动体积设定构件轴向移动。音量调节构件的转动还可以控制粗略的体积设定装置和微细体积设定装置，该音量设定装置响应于体积调节构件相对较小的转动，用于使音量调节构件移动相对较大的轴向距离，微细体积设定装置响应于体积调节构件相对较大的转动而使体积调节构件移动相对小的轴向距离。
