An assembly for dispensing fluid is described. In some implementations, an assembly can include a housing containing fluid, where the housing includes a conduit. The assembly can also include an actuator operably attached to the conduit of the housing. The actuator can include a body portion surrounding a cavity a tip portion having a fluid path that is fluidly connected to the cavity, the cavity being fluidly connected to the conduit, and a channel support including a fluid passage space under pressure. The assembly can further include a collector having a collection zone configured to collect the fluid dispensed by the actuator.
