Abstract
The invention relates to a means for separating magnetic particles from a composition. The means comprises an elongated protective cover (1) that comprises a recess (2) extending from the upper end towards the lower end thereof, the recess comprising a movable magnetic rod (4), the proportion of the length of the rod to its thickness being at least about 2:1. The invention can be used in different applications especially in the fields of biotechnology, biochemistry, and biomedicine. Collecting particles by using the means is easy and fast.
Claims13
A means for separating magnetic particles from a composition, comprising:
- (a) a separation rod comprising a rod magnet including an elongated magnet at a lower end and a ferromagnetic arm attached to the elongated magnet;
- and
- (b) an elongated protective cover with a tip,
- wherein the resulting magnetic field is strongest at the lower end of the separation rod for accumulation of the particles from the composition on the tip of the protective cover, and wherein the protective cover covers the separation rod and is movable with respect to the rod, for release of the particles from the means for separating.
A method for separating magnetic particles from a liquid composition in a vessel, comprising:
- (a) providing a means for separating the magnetic particles, comprising:
- (i) a separation rod comprising a rod magnet including an elongated magnet at a lower end and a ferromagnetic arm attached to the elongated magnet;
- and
- (ii) an elongated protective cover with a tip, wherein the resulting magnetic field is strongest at the lower end of the separation rod, and wherein the protective cover covers the separation rod and is movable with respect to the rod;
- (b) placing the means for separating in the vessel containing the composition to accumulate the particles from the composition on the tip of the protective cover;
- and
- (c) removing the means for separating, along with the particles, from the vessel.
