Strict quality control, medical-grade cleanliness standards

Each needle undergoes 100% hermetic/pressure testing and surface cleaning treatment, compliant with ISO 13485 medical device quality management system and USP Class VI biocompatibility standards. It ensures sterility, non-pyrogenicity, and zero residue, meeting the rigorous demands of clinical environments.

Smooth surface, low friction and easily operate

The needle body is finished with precision polishing to a mirror-like surface, significantly reducing puncture resistance and tissue friction, minimizing tissue drag injury, and facilitating instrument assembly and clinical handling.

FAQs:

Q: How is this straight-tail cannula fixed to the equipment?

A: Although the tail appears smooth, its outer diameter is usually precisely machined to fit snugly into​ matching Luer fittings or glass capillaries, relying on friction or interference fit to maintain a stable connection. It can also be secured externally using adhesives, O-rings, or micro-clamps if needed.

Q: What is the material of the product? Is it suitable for implantation or contact with organisms?

A: The product is typically manufactured from medical-grade stainless steel (e.g., 304 or 316L)​ with a polished surface, offering excellent biocompatibility and corrosion resistance, making it ideal for animal experiments, minimally invasive medical device components, or in vitro diagnostic equipment.

Q: In which specific experimental or medical scenarios can this needle be used?

A: Commonly used for stereotaxic injection in mouse/rat brains (lateral ventricle administration), micro-volume liquid transfer, tissue flushing, and as a guide cannula for microdialysis probes. Its slender design with a side hole is particularly suitable for precise and gentle fluid control in confined spaces.
