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。

摘要： A liquid chromatography column apparatus which utilizes sorbent packing material in a tube having a first end portion and a second end portion. The first end portion of the tube includes a plug having a passage therethrough. The plug fits in the tube adjacent the packing material and is movable within the tube. 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.
摘要翻译：一种在具有第一端部和第二端部的管中使用吸附剂包装材料的液相色谱柱装置。管的第一端部包括具有穿过其的通道的塞子。插头适合于与包装材料相邻的管中，并且可在管内移动。在塞子附近也采用端部配件。端部配件具有穿过其的通道，其与插头的通道连通。在管和端部配件之间的管内使用密封。管的第二端部被封闭，并且还包括从管的内部到外部的通道。手动致动的齿轮机构结合在管的第一端部的端部配件中，以便于对包装材料施加轴向力，从而压缩包装材料，以消除包装材料中的空隙和通道。还公开了其他特征。
