Coagulation Reagent Needle with stirring function

Dual Function: Dispensing + Stirring
Purpose-built for coagulation analyzers — dispenses reagent and then stirs the plasma–reagent mixture with the same probe, removing the need for a separate mixing mechanism, shortening cycle time, and eliminating the cross-contamination an extra component would bring.

OEM Geometry for Uniform Mixing
Precision-machined to OEM geometry and tolerances — tube straightness, concentricity, and tip dimensions identical to the original — ensuring stable stirring action, uniform mixing, accurate dispensing volume, and zero-deviation sampling timing.

Corrosion-Resistant, Anti-Fibrin Surface
Medical-grade 316L stainless steel with a mirror-polished, inert, corrosion-resistant internal bore, plus a specially prepared outer surface that prevents fibrin strands from wrapping and adhering to the needle during stirring.

Elevated Carryover Control
The integrated automatic wash (external flushing + through-needle internal purge) drives carryover to ultra-low levels — essential here, since the needle enters the reaction mixture and carries a higher contamination risk than a pure dispensing needle.
