FAQ:

Q1: What IVD scenarios is this sampling needle suitable for?

A: It is suitable for sample collection (e.g., serum, plasma, urine) of fully automated biochemical analyzers, immun analyzers, and POCT instant testing devices, as well as laboratory micro - fluid handling (e.g., reagent dispensing, calibration品 addition). The side - port design is particularly suitable for precise sampling of high - viscosity and bubble - prone samples.

Q2: What are the advantages of the side - port over the traditional end - port?

A: Traditional end - ports are prone to air bubble ingestion (especially for high - viscosity samples) due to negative pressure and have large fluid resistance. The side - port reduces bubble generation through "tangential liquid intake" and lowers sampling resistance. Combined with inner wall polishing, it can achieve "zero - residue" sampling (residue volume ＜0.1μL).

Q3: What is the adjustment range of the T - handle? Can it be adapted to our customized device?

A: The angle adjustment range of the T - handle is ±15°, and the length fine - tuning range is ±2mm​ (can be extended to ±10mm by replacing the extension rod); the mounting hole positions support double - ear (hole spacing 10mm/20mm optional) and single - ear​ customization. It can be pre - assembled and verified with your device's 3D drawing (free first - piece trial assembly service is provided).

Q4: Will there be any impact on performance after sterilization? Is there a limit to the number of reuses?

A: After 100,000 times of high - temperature and high - pressure sterilization cycles, the needle body strength (tensile strength retention rate ＞95%), dimensional accuracy (tolerance still ≤±0.015mm), and port patency (no blockage/deformation) all meet IVD requirements; if single - use is required, independent sterile packaging (gamma irradiation sterilization, SAL = 10⁻⁶)​ is available.
