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.

Q4: What is the main application of this product?

A:This product is specifically developed for medical IVD (In Vitro Diagnostic) applications, mainly used as a sampling / piercing probe in automatic clinical chemistry analyzers, immunoassay analyzers, hematology analyzers and coagulation analyzers, where it pierces stoppers of blood collection tubes or reagent bottles to aspirate and dispense biological samples or reagents. Manufactured from medical grade 316L stainless steel with electropolished finish, it is designed for highprecision, repeatable liquid handling inside certified diagnostic instruments and is not intended for direct human invasive procedures.
