GV-700 can maintain a vacuum of 50mL or 100mL in the pump body. This allows the user to attach the appropriate tube to pump, and then in situations where it is necessary, to take the sample using one hand. In the body of the Adapter there is a small rod which can be moved in or out quite easily with one finger.
