Exquisite craftsmanship and excellent accuracy
The whole product is processed by CNC precision machining
technology. The straightness of the needle body, thread precision,
and needle tip angle are strictly controlled to ensure batch
consistency, meeting the needs of high-precision medical
operations.
Smooth surface and low resistance
The needle body and base surface are polished/Passivated, with low
roughness, reducing liquid residue and tissue friction resistance,
and improving fluid passability and operational smoothness.
Multi-scene adaptation and flexible expansion
The standardized interface and sharp-tip design are suitable for
multiple medical scenarios (such as local delivery, minimally
invasive puncture, sample collection, etc.). It can also be used as
a substrate for customized medical components, with strong
expandability.
FAQs:
Q: What is the difference between this needle and a regular
straight needle? Why does it have threads and a flange?
A: Regular straight needles are mostly for free puncture, while
this needle is designed for precise fixation. The threaded tail allows secure connection to syringes, catheters, or dedicated
fixtures to prevent slipping. The flange (disc) in the middle acts as a stopper to ensure consistent insertion
depth, preventing over-penetration and injury, mainly used for micro-volume, controlled delivery or nutritional feeding.
Q: What is the material of the needle? Is it suitable for
experiments with high biocompatibility requirements?
A: This product is made of imported medical-grade stainless steel (e.g., 304/316L) with precision manufacturing and strict electropolishing. It
features high surface finish, excellent biocompatibility, corrosion resistance, and high toughness, making it safe for rodent (rat/mouse) experiments and various
biomedical micro-operations.
Q: In which fields is this type of needle mainly applied?
A: Mainly applied in life science research (e.g., animal gavage, nasogastric feeding,
stereotactic micro-injection), medical device R&D, in-vitro
diagnostics (IVD), and fluid control for small precision
instruments.
Q: What is the side opening style and shape of the needle tip? How
is the liquid flow rate ensured?
A: The tip features a micro side-opening with a beveled cut, and the edge is finely polished to be smooth without burrs. This
design effectively reduces friction during tissue puncture while guiding fluid flow directionally, ensuring a stable flow rate that is less prone to bubbles or
backflow, ideal for micro-perfusion sensitive to flow speed.
Q: What is the thread specification? Can it be adapted to syringes
or equipment from other brands?
A: Standard threads are Metric M6 or UNF 1/4-28 (depending on the model, please consult customer service for
specifics). Our thread tolerances are strictly controlled, allowing
perfect compatibility with most mainstream micro-syringes, Luer connectors, and custom
fixtures. We recommend confirming your interface dimensions before
ordering.
