Ring Magnet Benefits:
SBS footprint for broad compatibility, gripper grooves for easy robot access, and integrated Spring Cushion Technology
Alpaqua magnet plates with integrated Spring Cushion Technology give way when tips come in contact with a well bottom. This compensates for physical tolerances between labware and pipettors that can compromise precision aspiration and ultimately improve pipetting.
The 96S is compatible with a variety of microplate types such as PCR plates, deep well plates, U- & V-bottom plates and most skirted, non-skirted, and semi-skirted 96-well PCR plates.
Example plates that work well include the Corning Costar 3795 (round bottom), ABgene AB-2800 SuperPlate (low profile skirted PCR plate), ABgene AB-1127 (1.2 mL square well storage), ABgene AB-0661 (2.2 mL round bottom storage) and the Ritter riplate (2 mL round bottom storage).
There are many more plates that are fully compatible with the 96S. If you are unsure of your microplate compatibility, contact Alpaqua scientists or submit a sample to Alpaqua for testing.
Alpaqua generally recommends rigid PCR plates, like the Bio-Rad Hard-Shell, Eppendorf twin.tec, or 4titude FrameStar plates. The reason is that single-component polypropylene plates can sometimes be warped, especially after thermocycling. A warped plate can be difficult for a robot gripper to properly place on the magnet.
If the work is done by hand, then this is not an issue; the user can press the plate down on the magnet manually to ensure proper seating. Also, some plates are better than others, so it is absolutely possible that a non-rigid plate may work just fine, even on a robot. But for an automated workflow, rigid plates are a safer, more reliable choice.
The full-skirted Eppendorf® twin.tec 96 well PCR plate is not compatible because the wells do not reach far enough into the magnet ring. The semi-skirted and non-skirted versions of this plate are fine.
The 96S is generally not recommended for use with flat bottom plates.
