Abstract
A particle dispensing device including a hollow tube and a plunger inserted through the tube is used to transport and dispense solid reagents such as resin. The particle dispensing device can be coupled to a dispenser assembly that is a component in an automated system for processing biological materials.
Claims29
A particle dispensing device having a proximal end and a distal end, said particle dispensing device comprising:
- a hollow tube having a proximal end with an opening, a distal end with an opening, and an inside surface;
- a plunger slideably inserted through the proximal end of the hollow tube;
- and
- one or more particles of solid reagent disposed within the distal end of the hollow tube.
A particle dispensing device having a proximal end and a distal end, said particle dispensing device comprising:
- a hollow tube having a proximal end with an opening, a distal end with an opening, and an inside surface;
- and
- a plunger slideably inserted through the proximal end of the hollow tube,
- wherein the proximal end of the particle dispensing device is configured to be coupled to a dispensing assembly comprising an array of particle dispensing devices.
A particle dispensing device having a proximal end and a distal end, said particle dispensing device comprising:
- a cylindrically shaped hollow tube having a proximal end with an opening, a distal end with an opening, and an inside surface;
- a cylindrically shaped plunger slideably inserted through the proximal end of the hollow tube, said plunger having a proximal end and a distal end, the proximal end of the plunger configured for coupling to a flat plate, wherein a space is formed between the distal end of the plunger and the distal end of the hollow tube, said space defining a predetermined volume;
- and
- one or more particles of a solid reagent substantially filling the space formed between the distal end of the plunger and the distal end of the hollow tube,
- wherein the proximal end of the particle dispensing device is configured to be coupled to a dispensing assembly comprising an array of particle dispensing devices.
A method of dispensing a solid reagent comprising:
- providing a particle dispensing device comprising:
- a hollow tube having a proximal end with an opening, a distal end with an opening, and an inside surface;
- and
- a plunger having a proximal end and a distal end, said plunger slideably inserted through the proximal end of the hollow tube;
- positioning the plunger within the hollow tube so that a space is formed between the distal end of the plunger and the distal end of the hollow tube, said space defining a predetermined volume;
- positioning the distal end of the hollow tube over a reservoir comprising one or more particles of said solid reagent;
- forcing the distal end of the hollow tube into the reservoir, thereby filling the space with one or more particles of solid reagent;
- positioning the particle dispensing device over a solid support;
- and
- using the plunger to push the one or more particles of solid reagent out into the solid support.
