FAQ:

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

A: Yes. We use 316LVM or equivalent medical-grade stainless steel, compliant with ISO 13485 and passing biocompatibility tests (e.g., cytotoxicity, sensitization), ensuring safe and contamination-free use in IVD applications.

Q2: What is the precision of the needle tip? Can it ensure accurate transfer of trace amounts of liquid?

A: The tip is processed by ultra-precision grinding, with a minimum diameter down to micron level. Liquid transfer accuracy reaches within ±1%, meeting μL or even nL-level sample spotting/injection needs.

Q3: Is compatibility with automated equipment (such as chromatographs and mass spectrometers) supported?

A: Yes. The fixation flange/threaded hub of the needle can seamlessly connect with mainstream automated injectors, chromatograph/mass spectrometer injection modules. We provide customized interface solutions based on your device model to ensure stable installation and operation.

Q4: How to control the cleanliness and residue level of products?

A: We control cleanliness via triple processes: electrolytic polishing + ultrasonic cleaning + high-temperature baking, with surface roughness Ra≤0.4μm and near-zero residual volume. Production is completed in a GMP-compliant cleanroom, and final products pass particle counting and microbial testing before shipment.
