Method and Device for Handling Sedimenting Particles
First Claim
1. A method for manipulating particles suspended in a carrier liquid, comprising the steps:
- take-up of the carrier liquid containing the particles into a liquid siphoning device,generation of electric and/or magnetic separating fields in the liquid siphoning device,sedimentation movement of the particles in the liquid, wherein each particle has sedimentation speed which depends on an effect of the separating fields on the particle, and the particles form a plurality of particle fractions as a function of their sedimentation speeds, anddischarging of the particle fractions from the liquid siphoning device.

Abstract
The invention relates to a method for handling particles (1, 2) that are suspended in a carrier liquid (3). The method includes the following steps: the carrier liquid (3) is received with the particles (1, 2) in a liquid siphoning device (10) including at least one siphoning opening (11), electrical and/or magnetic separating fields are generated in the liquid siphoning device (10), a sedimentation movement of the particles (1, 2) is created in the liquid, each particle having a sedimentation speed that depends on the action of the separating fields on the particle (1, 2) and the particles (1, 2) forming a plurality of particle fractions (5, 6) according to the sedimentation speeds thereof, and the particle fractions (5, 6) are separately extracted from the liquid siphoning device (10). The invention also relates to a handling device (100) for handling suspended particles (1, 2).
