摘要： A releasably attachable manual dispensing aid is operable with a syringe having a syringe body and a syringe plunger that is movable within the syringe body. The dispensing aid includes a dispensing aid body that is releasably attachable to the syringe body. The dispensing aid further includes a dispensing aid plunger that is attachable to the syringe plunger, and has a slide that is slidable within the dispensing aid body. A fine adjustment, bottom stop, Chaney stop, and/or drag brake for the slide are optionally provided. An electronic linear position measuring device has a first portion fixed to the dispensing aid body and a second portion fixed to the dispensing aid plunger. Optionally, the dispensing aid includes a microprocessor that receives as inputs a calibration value for a particular syringe and the position signal, and determines as an output signal the true volume of liquid displaced by the syringe plunger movement.

摘要： A liquid handling system includes a translation mechanism, and a probe mounted on the translation mechanism. The probe has a number of lumens extending along the length of the probe. The lumens are open at their lower ends and connectable at their upper ends to a compressed air source and sources of liquid solvents. The system further includes multiple seal heads that can be attached to the lower end of the probe to perform various functions. Some seal heads seal to the tops of various sized containers placed below the probe, with a cylindrical splash guard overlying the exterior of the top of the container to prevent splashes that might injure personnel. Other seal heads rotatably attach to other structures, such as filters. The seal heads may be parked and then used, one at a time, by inserting the probe into the appropriate seal head. After use, the seal head is returned to the parking location and drawn off the end of the probe.
