A multi-pipette system of the type having sample volume determined by size of cavities into which flexible membrane portions are drawn, provides a microporous block with the cavities formed in it for drawing the flexible membrane into the cavities when pressure is reduced above the microporous block. Slide-in-place location and replacement is provided for supply containers, disposable tube arrays for drawing up samples and for expelling them, and for flexible membranes. In an embodiment microporous block cavity size is adjustable.
