SHOMEA Medical-Grade Stainless Steel IVD Multi-Channel Coaxial Sampling Needle

Manufactured from medical-grade 316L stainless steel, offering excellent biocompatibility and corrosion resistance

Multi-channel coaxial design enables efficient processing of multiple samples

Mirror-polished inner wall (Ra ≤ 0.4μm) + physical isolation between channels

Mirror-polished surface finish, exceptional mechanical strength and wear resistance

Precision welding technology ensures seamless construction without burrs, low surface roughness

FAQ:

Q1: What are the standard channel numbers and dimensions? Do you support non-standard customization?

A: Standard channel numbers: 3, 4, 5; standard tube diameter Φ1.0–Φ2.0mm, length 50–150mm. Full-dimensional customization is supported: channel number, tube diameter, length, tip morphology (straight/bent/side-hole), connector (Luer/quick-plug), etc., all adjustable on demand.

Q3: How does the multi-channel design avoid cross-contamination?

A: ① Physical isolation between channels (independent lumens, no fluid crosstalk); ② Mirror-polished inner wall (Ra ≤ 0.4μm) to reduce sample residue; ③ Directional hole/burring treatment at the tip to avoid sample adhesion. Actual residual volume ＜0.1μL, cross-contamination rate ＜0.01%.

Q4: Which IVD devices is it compatible with?

A: Compatible with automated IVD analyzers (e.g., biochemical, immunological, molecular diagnostic devices), POCT devices (handheld/desktop), microfluidic chips, etc. Customizable channel number, length, and connector according to the device’s fluidic path layout to ensure seamless integration.
