Abstract
Aspects of the invention relate to liquid transfer systems including a pipette tip having a body defining an inner volume and having first and second ends, the first end arranged to transfer a volume of liquid into and out of the pipette tip and the second end arranged for attachment to a pipette, and a bladder sealingly attached to the body. In some embodiments, the bladder is disposable in the inner volume. The bladder may be defined by a membranous sac and/or a planar membrane. The bladder may be moveable in response to an applied pressure to transfer liquid. The bladder also may be stretchable to accommodate a volume of fluid. In some embodiments, the pipette tip is used in a cell culture incubator, with a manipulator including a pipette that is in fluid communication with the pipette tip.
