Check the listing for details. Magnetic rack beads separator biomolecules purification, 5 mL - 50 mL tubes. Condition: New. Listed at 49.00 USD. A separator for purifying DNA, RNA, or other biomolecules with magnetic beads. Designed to hold 50 mL, 15 mL or 5 mL centrifuge tubes with conical bottom.It contains the strongest possible neodymium magnets, which effectively pull magnetic beads from the suspension towards the side of the tube, clearing the solution within a few minutes. Beads accumulate near the wall, somewhat above the bottom of the tube, so you can easily pipette all the liquid out without worrying about accidentally uptaking any beads.To use, insert your tube into the rack and wait for a few minutes until the solution clears.This rack works with any magnetic bead-based purification kit, including Dynabeads, Ampure beads, and others.Great for many applications, for example, purification of a PCR product or selecting DNA strands of a specific size from the DNA library.Technical specification: - Dimensions: 108 x 85 x 58.5 mm- Contains neodymium magnets of N52 grade- Color: white- Fits 2 tubes simultaneously- Beads will be pulled 3-4mm up from the bottom of a typical 50 or 15 mL tube- Compatible with 5 mL centrifuge tubes- Compatible with 15 mL centrifuge tubes
