Purification Comparison

Category Spin Column Method Magnetic Bead Method
Equipment Spin column for Centrifuge Machine Magnetic
Time More than 30 minutes Less than 10 minutes
Scale Need various scale and kind of spin column Simply increase the quantity of Bead
Equipment Automation Possible but need centrifuge machine or vacuum pumps (Increase Equipment footprint) To process various samples in a short time (Decrease equipment footprint)
