Sample needle for Sysmex Coagulation Analyzer CA7000

Sample Aspiration & Cap-Piercing
Purpose-built for the Sysmex CA-7000 — high-precision aspiration of patient plasma from the collection tube, combining closed-tube piercing and aspiration in a single needle.

Smooth Piercing, OEM Geometry
A precision-machined tip angle and edge sharpness ensure smooth stopper penetration without rubber fragments, while OEM bore diameter and taper secure accurate aspiration volume and consistent sampling timing.

Low-Binding, Residue-Free Bore
Medical-grade 316L stainless steel with a mirror-polished, inert, low-binding internal bore that prevents plasma protein from adhering to the wall.

Carryover Control — Clinically Critical
The integrated automatic wash (external flushing + through-needle internal purge) drives inter-sample carryover to ultra-low levels, keeping cross-contamination from perturbing clotting times.
