The 96R and 96S magnet plates are the original "SPRIPlates" designed by Agencourt Bioscience for use with the SPRI magnetic bead chemistry
96S Super Magnet Plate
Allround economical magnet plate
Product is identical with Beckman Coulter P/N A32782, and can be used with a wide variety of 96-wll PCR plates and -strips. Recommended reaction volume up to 1000 µL.
On a ring magnet plate the magnetic beads form a circle around the perimeter of each well bottom. This leaves a bead-free area of several millimeters in diameter in the center of the well allowing pipet tips to efficiently aspirate sample supernatant, wash fluids, or eluates. The 96S Magnet plate contains stronger magnets than the 96R, which allows for faster magnetic bead separation.
The 96S plate contains integrated Spring Cushion Technology so you can get that last microliter without bending tips! Spring Cushion Technology allows the microplate to give way when tips come in contact with a well bottom, thus compensating for physical tolerances between labware and pipettors that can compromise precision aspiration.
