FAQ:

Q1: Does the material of this needle truly meet medical-grade standards?

A:Yes. The product is made of medical-grade stainless steel​ (e.g., 316L or equivalent), which has passed biocompatibility tests (e.g., cytotoxicity, sensitization testing) and meets the strict safety and hygiene requirements of the IVD industry, ensuring safe contact with biological samples.

Q2: Can the length and bending angle of the needle body be customized?

A:Customization is supported. We can flexibly adjust the needle length, L-shaped bending angle, as well as the size of the flange/knob according to your equipment interface, operating space, sample type, and other requirements, ensuring perfect adaptation to your IVD instruments.

Q3: Is the puncture resistance of the needle tip high? Will it damage samples or equipment?

A:The needle tip adopts a precision polishing + micro-bevel design, with extremely low puncture resistance. It can collect samples (such as blood, body fluids) in a minimally invasive way, which not only reduces damage to the sample (e.g., cell activity, protein structure) but also lowers the risk of wear to equipment pipelines/components.

Q4: Is the fixing method of the flange firm? Will it shift during operation?

A:The flange adopts a double-hole screw fixation + knob locking​ dual design, with strong stability after installation; the knurled texture of the knob increases friction, and tightening after adjustment can firmly fix the needle body, avoiding displacement due to vibration or external force during the experiment, ensuring operational repeatability.
