    摘要： A digital dispense system and method of using a digital dispense system, with unique low-cost pipette-fillable cartridges that provide feedback to a user if fluid chambers of the cartridge do not contain fluid or an incorrect fluid is pipetted into a fluid chamber, are provided. The digital dispense system includes a pipette-fillable fluid cartridge having one or more fluid chambers therein and having an ejection head attached thereto. The ejection head contains fluid ejectors thereon. The fluid ejectors are in fluid flow communication with the one or more fluid chambers of the pipette-fillable fluid cartridge. A fluid detection circuit is disposed on the ejection head and associated with at least one of the fluid ejectors for signaling the presence or absence of fluid in the one or more fluid chambers.

    摘要： The present invention provides a telescoping electric pipette controller, which comprises a handle, a head end portion, an outer shell and a manual retainer, wherein one end of the head end portion is arranged in an end portion of the handle in a penetrating manner, the outer shell is sheathed over an outer surface of the end portion of the handle, and one end portion of the manual retainer is rotatably connected to the outer shell; and by means of opening or fastening the manual retainer, one end portion of the manual retainer is released outwards or pressed inwards against the head end portion, allowing extension and retraction of the head end portion relative to the handle. According to the present invention, the extension and retraction and the locking of part of a grip structure are controlled by means of a switch of a mechanical structure, such that the grip can change the length within a specific range as desired, achieving adjustment of the length of the grip as desired.

    摘要： A microfluidic device for isolation objects from a liquid suspension comprises at least one fluid inlet and at least one fluid outlet, at least one fluid channel fluidically connecting the at least one fluid inlet to the at least one fluid outlet, a plurality of passive hydrodynamic trapping sites arranged along the at least one fluid channel, each trapping site configured to trap a defined number of objects from a liquid suspension flowing along the at least one fluid channel, and a plurality of nozzle channels, wherein each nozzle channel is in fluidic communication with one of the trapping sites and fluidically connects this trapping site with an associated nozzle orifice. A force may be applied concurrently to the trapped objects and the liquid columns in the nozzle channels so that a liquid aliquot containing the defined number of objects is ejected from each nozzle orifice.
