Magnetic Separator Stand 50, for 50 mL Conical Tubes

Product Overview

The Magnetic Separator Stand 50 holds conical 50 mL centrifuge tubes against a permanent magnet array, pulling superparamagnetic beads to the tube wall so the supernatant can be drawn off without centrifugation or filtration. It generates a field of 4000 Gs, which is what makes separation practical at 50 mL — the volume where a small-tube stand runs out of reach.

This is the preparative-scale member of the BEAVER separator range. It is the matching stand for protein purification at 2 × 50 mL and 4 × 250 mL bead volumes, and for nucleic acid extraction from large sample volumes.

How to use it

Place the tube in the stand, let it stand a few minutes until the beads are drawn to the wall and the solution clears, then remove the solution with a pipette. Separation time is not fixed: it depends on bead diameter — smaller beads take longer — and also on the viscosity and composition of your solution. Sub-micron beads in a viscous lysate can take several times longer than micron beads in buffer. An elongated pipette tip makes it easier to reach the bottom of a 50 mL tube without disturbing the pellet.

Safety — read before use

This is a strong permanent magnet, not an electromagnet. It cannot be switched off.

Keep it away from electronics, watches, magnetic storage media and any object sensitive to magnetic interference. Anyone with an implanted electronic device such as a cardiac pacemaker should maintain a safe distance of at least 50 cm. Prevent metal objects from being pulled onto the magnet — knives and other blades in particular, which can injure the operator on impact.

Do not disassemble the separator. Do not use it above 50 °C or in a strong external magnetic field. Strong acids, alkalis and organic solvents corrode it; avoid contact. Clean by wiping with a damp cloth and drying — not with alkaline solutions or detergents. Avoid prolonged sunlight or UV exposure. Store it in its box in a dry, cool place, and never leave it stuck to an iron plate or to another magnet. If the magnet works loose, stop using it and contact us for service.
