384-well Magnet Plates

Alpaqua 384 Post Magnet Plate

The 384 Post Magnet Plate contains 96 Neodymium-Iron-Boron (NdFeB) post magnets - one for each group of four wells. It is designed for 384 well PCR plates. We strongly recommend rigid plates (dual-component-plates) because simple PP-plates may warp - sometimes right out of the box, but certainly after thermocycling.

Rigid 384 -well PCR plates are available from three vendors:

- Bio-Rad Hard-Shell® plates

- Eppendorf twin.tec® plates

- 4titude FrameStar® plates

The ABgene Diamond Plate AB-1111 that we used to recommend here is no longer available, but the three models above all work very well.

Like all Alpaqua magnet plates, the 384 Post Magnet Plate contains patented* spring cushion technology to greatly simplify supernatant removal and eluate transfer.



Note: This magnet plate is identical to Beckman Coulter P/N A29165.

Plate Features
  • Optimized for robotic access
  • Post magnets for use with high density PCR plates
  • Strong NdFeB magnets for efficient bead capture
  • 15 µl elution volume
  • Compatible with common magnetic bead chemistries and protocols for product and application flexibility
  • Integrated spring cushion technology for complete liquid removal without tip occlusions
Post Magnets

The Alpaqua 384 Magnet Plate contains strong, Neodymium-Iron-Boron (NdFeB) post magnets for efficient magnetic bead separations with automation in mind. They have an SBS footprint to fit into standard liquid handler plate nests, plate hotels and stackers as well as gripper grooves on the long sides to provide space for robotic arms or grippers when moving microplates on and off the magnet plates.

Integrated Spring Cushion Technology

All Alpaqua magnet plates contain integrated Spring Cushion Technology. This technology allows plates 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.

Liquid level at 10 - 12 - 15 - 18 - 20 µl elution volume in a 4titude FrameStar® 384-well PCR plate. 40 µl of undiluted Ampure XP was added to the wells to obtain clearly visible bead spots. After removing supernatant, the above volumes were added. The experiment shows that 15µl of elution buffer is sufficient to completely cover the beads.
Plates are compatible with 384-well PCR plates
A single post magnet simultaneously sequesters magnetic beads into the corners of four wells
Alpaqua offers a line of magnet plates for use with 24-well, 96-well, 96-deepwell and 384-well microplates
