<p>The invention is a device and method for separating liquids from solid particles in a laboratory. The device consists of a pipette tip, which has holes or slots arranged radially around the axis of the tip and the lower end of the tip, closed. The smallest dimension of the hole or slit is smaller than the diameter of the solid particles from which the liquid is to be separated. These holes or slits are positioned towards the lower end of the tip such that when plunged into a sample, they are below the level of the phase to be extracted. The method comprises mounting the device on a manual or robotic pipettor, plunging the tip into a mixture of solid particles and liquid to be separated, aspirating the liquid and removing the tip with the aspirated liquid, leaving the solid particles behind in the original container.</p> |
