FAQ:

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

A1:Suitable for micro-sample collection, injection, or spotting in automated diagnostic equipment such as High-Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), Mass Spectrometry (LC-MS/MS), Immunoanalyzers, and Nucleic Acid Extraction Instruments. Applicable to therapeutic medicine monitoring, metabolomics analysis, infectious disease marker detection, etc.

Q2:Is the material biocompatibility certified?

A2:Yes. We use medical-grade 316L stainless steel​ (or 316LVM), compliant with ISO 10993 biocompatibility standards, safely contacting human samples (blood, serum, urine, etc.) without cytotoxicity, sensitization, or irritation risks.

Q3:Can the needle length, outer diameter, or hub be customized?

A3:Absolutely. We support non-standard customization based on customer equipment interfaces (e.g., thread specifications M6/M8, flange dimensions), needle length (50mm-300mm optional), outer diameter (0.3mm-1.2mm optional), tip angle (e.g., 15°/30° bevel), etc. Contact our technical support for exclusive solutions.

Q4:How is the cleanliness of the needle body ensured? Will there be cross-contamination?

A4:The needle undergoes electropolishing + ultrasonic cleaning + high-pressure sterilization​ (optional), with surface roughness ≤0.4μm and extremely low residual particles/proteins. For reusable needles, regular maintenance with dedicated cleaning reagents is recommended; or choose our disposable sterile version​ to avoid cross-contamination from the source.

Q5:What is the minimum sample volume that can be handled?

A5:Thanks to the ultra-fine tip (inner diameter can be as small as 0.1mm) and precision manufacturing, our sampling needle can accurately handle 1μL-100μL​ of micro-liquid (depending on inner diameter and injector pump precision), meeting the "micro-precision" needs of IVD.
