NdFeB Magnets For Magnetic Bead Separation Racks | Lab Instruments & Equipment
NdFeB magnets for magnetic bead separation racks is another magnet application for laboratory instruments & equipment. In previous article, we introduced different rare earth magnets for magnetic stir rod.
What is Magnetic Bead Separations System?
Magnetic Bead Separations System is a laboratory tool that can isolate all types of magnetic beads efficiently. It is also a popular magnetic bead separation devices for life scientist.
This biological separations system consists of three parts: the magnetic bead, test tube and magnetic bead separation rack. Among them, magnetic bead separation rack is the core part of this product.
They are specially designed for rapid and effective small-scale separations between liquid and magnetic beads.
The magnetic separator racks has many different structures, but all of magnetic separation racks will made rare earth magnets embedded housing. These powerful magnets will capture the magnetic beads in 10-20 seconds.
These magnetic racks are suitable for biological separation, such as antibody purification, immunoprecipitation, co-immunoprecipitation, cell sorting, and nucleic acid isolation.
What Magnetic Bead Separation Magnet To Use?
Good magnetic racks are using neodymium magnets. Almost all of magnetic separation stand companies use the most powerful commercially available – Neodymium Iron Boron (NdFeB) rare earth magnets, to ensure the fastest separation time possible with the least amount of bead loss.
For room temperature working environment, Neodymium magnet 52 MGO is best choice. There are other lower grades like N50, N48, N45, N42 available too.
The neodymium magnet shapes varies from disc, rod, cylinder to block. These depends on your unique design. Sometimes you many need irregular shape magnet to fit your rack structure. China Magnets Source Material Limited can custom strong neodymium magnets in many shapes, no matter simple shape or trapezoid-shaped.
