Japanese Patent JPH09500593
Kind Code:
A
Abstract:
A liquid transfer device including a holder for a pipette array. A flexible preformed membrane (17) having cups (19) is over the proximal openings of the pipettes (23) and sandwiched therebetween with a housing (11) with the cups extending into the proximal openings of the pipettes. A vacuum drawn in the housing everts the membrane from the proximal openings thereby creating reduced pressure in the pipettes which when their distal ends are immersed in a liquid will draw up some of the liquid into the pipettes in substantially equal amounts. In one embodiment a movable abutment (13) is provided to control the upward travel of the everting membrane and thereby the amount of liquid drawn into the pipettes. A method for fabricating the preformed membrane is also shown.
