Magnetic Particle Processors

Confirm the magnetic rod and tip comb mechanism moves smoothly and the plate carrier positions correctly. If the unit is heated, check the heater still reaches and holds its set temperature. Ask for the run count and a recent processing result to see it still recovers beads cleanly.

Match the plate capacity to your busiest run, since batching many samples is where these units earn their place. Compact designs handle a single plate, while multi plate models raise daily throughput. If your volume varies, a mid capacity unit usually gives the best balance.

These instruments use format specific tip combs and plates that must match the deck. Check these consumables are still in production before you buy. The seller can confirm current supply and whether compatible alternatives exist.

Programmable models handle several bead protocols, but the plate layout and volumes need to suit each chemistry. Confirm the unit supports the assays you run and lets you adjust protocols. A flexible design is worth having if you switch between extraction and assay work.

Platform sellers are vetted, and every listing includes condition information you can question directly. You contact the owner to confirm run history and included consumables before committing. That checked seller and direct line together lower the risk of a used purchase.
