Abstract
A pin-in-capillary apparatus for depositing droplets of fluid onto a surface is described. The apparatus has an off-axis channel for supplying fluid to the capillary. In the capillary the fluid wets the tip of the pin and is delivered to the surface when the pin is extended from the capillary. The capillaries and pins are flexible, allowing spatial reformatting for fluid delivery. Methods of delivering fluid to a surface are also described.
Claims20
An apparatus for depositing a fluid from a fluid source onto a substrate, the apparatus comprising
- an off-axis channel adapted to being fluidically coupled to said fluid source,
- a flexible capillary in fluid communication with the off-axis channel, the capillary having a downstream capillary end adapted to receiving fluid from said fluid source,
- a flexible pin slidably disposed within the capillary, the pin having a downstream tip disposed adjacent the downstream capillary end, the tip being adapted to being wetted by said fluid in the capillary, and
- a pin driver operably coupled to the pin,
- wherein the pin driver is operable to move the tip toward the substrate to deposit said fluid onto said substrate.
