FAQ:

Q:​ What material is this sampling needle made of? Does it meet biocompatibility standards?

A:​ This product is manufactured from high-quality 316L medical-grade stainless steel, fully compliant with ISO 10993 biocompatibility standards. It has excellent corrosion resistance, can withstand various IVD reagents and body fluids, ensuring no metal ion leaching and guaranteeing the accuracy of test results.

Q:​ What is the specific purpose of the 90° bent and lateral connection design?

A:​ This unique structure is specifically designed for complex IVD instrument internal layouts. The 90° bend allows the needle to avoid obstacles in confined spaces, while the lateral threaded connection facilitates quick and precise docking with reagent kits or microfluidic chips, effectively avoiding pipeline interference and improving the overall integration of the equipment.

Q:​ What is the machining precision of the product? Can it meet the injection requirements of microfluidic chips?

A:​ We use advanced Swiss-type CNC machining, with key dimension tolerances controlled within ±0.02mm. The inner and outer walls of the needle tube are processed with ultra-precision cutting technology, with surface roughness Ra≤0.4μm, ensuring precise fluid control, no residue, no blockage, and perfectly meeting the injection requirements of microfluidic chips.

Q:​ What are the functions of the red and black wires? What is the electrical performance?

A:​ The red and black wires are used to connect external sensors or heating/cooling modules (e.g., temperature probes, liquid level sensors, etc.). The wires are insulated with medical-grade materials, with a temperature resistance range of -40℃~+105℃, and can withstand AC 500V/1min without breakdown, ensuring electrical safety and stable signal transmission.

Q:​ Is the needle tube surface specially treated? Is it easy to clean and sterilize?

A:​ The needle tube surface is mirror-polished and passivated by electrolysis, forming a dense oxide film. This not only enhances corrosion resistance but also reduces the risk of protein adsorption and sample residue. It supports high-temperature and high-pressure sterilization (121℃, 30min) and ethylene oxide (EO) sterilization, and can be customized for reusable or single-use applications.

Q:​ Which IVD instruments or testing projects is this sampling needle mainly suitable for?

A:​ It is widely used in fully automatic biochemical analyzers, immunoassay analyzers, molecular diagnostic instruments (e.g., PCR, NGS), microfluidic chip detection systems, etc. It can be used for precise aspiration and transfer of serum, plasma, urine, cerebrospinal fluid, and other samples, and is compatible with the reagent slots and sample positions of mainstream brand instruments.
