FAQ

Q1: How is the corrosion resistance of this sampling needle? What reagents can it withstand?

A: The medical - grade stainless steel material endows it with excellent corrosion resistance. It can withstand common acid - base solutions, organic solvents (e.g., ethanol, isopropanol), some enzyme reagents, etc. in IVD testing for a long time; however, strong oxidizing acids (e.g., concentrated nitric acid) or high - concentration strong alkalis may have a certain impact on it. The specific tolerance range can be referred to the product technical manual.

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

A: The needle tip is finely polished, with low resistance and high smoothness during puncturing, which can reduce damage to the measured sample containers (e.g., blood collection tubes, reaction cups); at the same time, the sharp and uniform needle tip can improve sample collection efficiency and reduce the risk of sample residue.

Q3: Has the material passed biocompatibility certification? What test reports are available?

A: Made of 316L medical-grade stainless steel, certified by ISO 10993-5 (cytotoxicity) and ISO 10993-10 (sensitization), material reports and biocompatibility test reports (e.g., third-party CMA/CNAS reports) are available.
