Magnetic Separation Aspirate Needle

Magnetic-Separation Wash Function
Purpose-built for magnetic-particle immunoassay platforms — precisely aspirates and removes supernatant during the wash step while magnetic beads stay captured at the reaction site.

Low-Binding, Bead-Safe Bore
Medical-grade 316L stainless steel with a mirror-polished, inert, low-binding internal bore that minimizes bead/reagent adsorption and prevents wall residue.

Carryover & Bead-Adherence Control — Dual Defense
A specialized outer-wall coating reduces carryover and bead adherence, while the integrated automatic wash (external flushing + through-needle internal purge) drives carryover to the ultra-low level required for a clean signal.

OEM-Grade Precision & Fit
OEM-grade dimensional consistency delivers drop-in fit and repeatable aspiration volume — a reliable, cost-effective alternative for magnetic-separation wash applications.
