Sample Needle for Beckman Coulter

The needle body is precision-fabricated from medical-grade 316L stainless steel, with precision-ground and surface-hardened geometry that delivers a flat, wear-resistant tip — engineered to withstand continuous open-vial aspiration over extended operation without burring, curling, or deformation. A mirror-polished internal bore ensures smooth, residue-free fluid flow, while the automatic external probe wash works in concert to suppress wall adhesion and carryover contamination.

This compatible component unites durability with precision: it sustains stable aspiration performance through long-term continuous operation on the DxH 500, with a service life on par with the OEM equivalent. OEM-grade dimensional consistency safeguards volumetric repeatability at the 12 µL micro-volume level, needle after needle — making it a high-value, reliability-driven alternative for DxH 500 workflows.
