Abstract:
Filter pipette tip with a small tube with a relatively large aperture at one end for attaching to a pipette, a relatively small aperture at the other end for the passage of liquid and a through-channel between the large aperture and the small aperture and a porous filter arranged in the through-channel, filling up a portion of the through-channel and comprising at least two layers arranged in series in the direction of the through-channel of which a fine-pore layer has a pore size of a maximum of approximately 20 μm and a coarse-pore layer a pore size of approximately 20 to 50 μm, the two layers having different pore sizes.
