Abstract
In a fluidic device with a storage compartment communication is allowed between the storage compartment and other portions of the device. The communication is controlled through a valve arrangement and a membrane covering the compartment. The valve arrangement can be provided through a sealing clamp with clamp fingers. The clamp fingers control communication between the storage compartment and remaining portions of the fluidic device.
