FAQ:

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

A: Yes. This product is made of 316LVM medical-grade stainless steel, compliant with ISO 13485 medical device quality management system, and has passed biocompatibility tests (such as cytotoxicity, sensitization, skin irritation tests), fully meeting the medical-grade application requirements of the IVD (In Vitro Diagnostics) field.

Q2: What are the advantages of the tip design of the sampling needle?

A: The tip of our sampling needle adopts precision grinding process, with sharp and uniform edge, which can achieve accurate transfer of μL-level micro-liquid, while avoiding sample wall adhesion or residue; the ultra-fine and smooth inner wall of the needle further reduces liquid adsorption and improves detection repeatability.

Q3: Is the interface design compatible with common IVD devices?

A: Yes. The sampling needle is equipped with a knurled fixation flange/threaded hub, which can be firmly adapted to mainstream automatic samplers, chromatographs, mass spectrometers and other devices; if your device has special interface requirements, we support non-standard customization (such as M6, M8, 1/4-28UNF and other thread specifications) to ensure seamless docking.

Q4: Can sampling needles be customized according to our instrument model?

A: Absolutely. We have a professional R&D team, and can provide full-dimensional customization services such as needle length, outer diameter, inner diameter, tip angle, interface form, etc., according to the parameters of your instrument brand, model, needle cabin size, interface specification, etc., to ensure that the sampling needle perfectly matches your equipment.
