Apparatus and methods for droplet dispensing

摘要

Droplet dispensing apparatus and methods are disclosed for reducing or eliminating deleterious effects caused by pressure transients on the droplet dispensing action of a droplet dispensing device. The droplet dispensing device usually comprises a plurality of nozzles. In the method fluid reagents are passed through a porous medium and into the droplet dispensing device. The porous medium is usually adjacent an inlet into the droplet dispensing device. In one embodiment the porous medium is coated with a desiccant material. In another embodiment the porous medium is in combination with a second porous medium, which is coated with a scavenger material.
