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： A dashpot piston mounted in a closed chamber is coupled by an axially movable shaft to a pipette piston to regulate return movement of the pipette piston within a pipette cylinder to draw fluid into the cylinder. The dashpot shaft is movable within limits relative to the dashpot piston to accommodate a blow-out of residual fluid from the pipette by the shaft driving the pipette piston beyond a home position to blow residual fluid from the pipette cylinder. An air inlet port in the bottom of the chamber allows air to be drawn into the chamber with upward movement of the dashpot piston while a valve adjacent to the air inlet port opens in response to downward movement of the dashpot piston to exit air from the chamber. Control of the relative sizes of the air inlet port and valve outlet regulates the relative rates of upward and downward piston movement in the cylinder. The dashpot piston carries a movable plate of a variable capacitor transducer for monitoring the position of the pipette piston within the pipette cylinder.
摘要翻译：安装在封闭室中的缓冲器活塞通过可轴向移动的轴联接到移液管活塞，以调节移液管活塞在移液管气缸内的返回运动，以将流体吸入气缸。缓冲器轴可相对于缓冲器活塞在极限内移动，以通过驱动移液管活塞的轴超过原始位置来容纳来自移液管的剩余流体的吹出，以吹送来自移液管的残余流体。在室的底部的空气入口允许空气随着缓冲器活塞的向上运动而被吸入室中，同时与空气入口相邻的阀响应于缓冲器活塞向下移动以从腔室排出空气而打开。控制进气口和阀门出口的相对尺寸可调节气缸中上下活塞运动的相对速率。缓冲器活塞承载可变电容换能器的可移动板，用于监测移液管活塞在移液管内的位置。
