Manufactured from medical-grade 316L stainless steel, offering excellent biocompatibility and corrosion resistance
High - precision threaded connection + customized fixed bracket, significantly enhances the repeatability and accuracy of IVD testing
Integrated Design, Easy Installation & Integration
The surface of medical - grade stainless steel is passivated, exceptional corrosion resistance and long-lasting durability
Q1: Is the material of this sampling needle compliant with medical industry standards?
A1: Yes. We use medical - grade 316L stainless steel, which has passed the ISO 13485 quality management system certification and complies with ASTM F138 (stainless steel for surgical implants) standard. Biocompatibility tests (e.g., cytotoxicity, sensitization) are all qualified, and it can be safely used in the IVD sample contact link.
Q2: How is the precision of the sampling needle? Can it meet the needs of high - precision IVD testing?
A2: Our sampling needle has a concentricity＞99% and a needle tip positioning error of ＜0.01mm. Combined with the precision fixed bracket, the repeatability CV value of sample collection/transfer is ＜3% (the industry's excellent level is ＜5%), which fully meets the needs of high - precision IVD testing such as chemiluminescence and molecular diagnosis.
Q3: Is this sampling needle corrosion - resistant? Can it be used for samples containing acid and alkali?
A3: Yes. The surface of medical - grade 316L stainless steel is passivated, which can withstand the corrosion of acid - base environments with pH 1 - 14, common organic solvents (e.g., ethanol, methanol) and human body fluids (e.g., blood, serum) for a long time. In the IVD testing scenario, the service life can reach more than 5000 sampling cycles.
Q4: Can the length, diameter or interface of the needle be customized?
A4: Of course. We provide customization services for needle length (50 - 300mm), needle diameter (0.3 - 1.2mm), and interface type (e.g., SMA, BNC, custom threads). You just need to provide the equipment model or technical parameters, and our engineers will provide a customization plan within 24 hours.
Q5: What is the delivery cycle and minimum order quantity?
A5: The delivery cycle of standard products (conventional length, diameter, interface) is 7 - 10 working days, and the minimum order quantity is 50 pieces; the delivery cycle of customized products is 15 - 20 working days, and the minimum order quantity is 100 pieces. For urgent orders, we can provide expedited service (with an additional 10% - 15% expedited fee).
