Abstract
Devices and methods are provides for delivering fluids into reaction vessels. The present device is an interface head which allows a user to add reagents and wash solvents to a reaction vessel. Typically, the interface head can engage a plurality of these reaction vessels mounted in a cassette or frame and is adapted to removably engage passages leading into the reaction vessel. The interface head allows a user to manually inject materials into the plurality of passageways in the head which are fluidly coupled to the reaction vessel. In one embodiment, the interface head has a septa valve which opens and closes inlets of the plurality of passageways. The septa valve comprises an elongate member with a septum portion and a plurality of septum ports. The elongate member is slidable between a first position wherein at least one inlet of the passageways in the interface head is sealed by the septum portion and a second position wherein said at least one inlet is aligned with one of the ports to allow delivery of materials from the inlet into the reaction vessel. The septum portion is penetrable by needles and thus allows access for needle/syringe type delivery devices.
