FAQ:

Q1: What specific material is used, and is it suitable for contact with human blood and other bodily fluids?

A:​ We exclusively use 316LVM (Vacuum-Melted) medical-grade stainless steel. This alloy contains a low carbon content and added molybdenum, providing superior resistance to pitting and crevice corrosion caused by chloride ions in blood. It fully complies with ISO 10993 biocompatibility standards and is safe for direct, long-term contact with human blood, serum, and other bodily fluids.

2: What level of dimensional precision can you guarantee for the threaded connection and the side port alignment?

A:​ Our advanced 5-axis CNC machining centers ensure that the outer diameter (OD) and inner diameter (ID) of the needle shaft maintain a strict tolerance of ±0.01mm. The perpendicularity and concentricity of the side port relative to the central shaft axis are controlled within 0.02mm. This eliminates leakage risks and ensures a perfect seal when connected to pneumatic actuators or fluidic systems.

Q3: How does the threaded connector mate with standard IVD syringes or fluidic tubing?

A:​ The standard female thread is precision-machined to match common IVD fittings. We offer extensive customization for the thread type, including metric threads (e.g., M4x0.7, M5x0.8), G-threads, or Luer lock adapters. Additionally, the integrated mounting bracket features slotted holes, allowing for fine-tuning of the needle's insertion depth and angle within the diagnostic instrument chassis.

Q4: What is the expected lifespan if we plan to reuse these needles in our automated analyzer?

A:​ Thanks to the 316LVM material and a mirror-like electropolished surface finish (Ra typically < 0.2µm), the needle resists protein adsorption and thrombus formation. It is rated for 500+ high-temperature, high-pressure (HTHP) autoclave sterilization cycles. In rigorous internal testing, the dimensional stability remains excellent beyond 1,000 cycles, making it highly durable for high-throughput clinical analyzers.
