Zusammenfassung:	A dispenser (10) for applying small amounts of liquid to a substrate. The dispenser (10) includes a dispenser body (12), an actuator in the dispenser body, and a dispensing element including a dispensing element body (52) removably coupled to the dispenser body (12). A valve stem (60) is mounted for reciprocating movement within the dispensing element body (52). Additional aspects include a deformable valve seat (62), a deformable and resilient valve stem tip (60a) and a method of applying liquid in discrete amounts to a substrate.
