TAOMSUN analyzer sampling needles are precision-machined components designed for laboratory analytical instruments, providing reliable liquid sample handling for biochemistry analyzers and other laboratory analyzers. Materials SUS304, SUS316L, titanium and titanium alloy, meeting different corrosion resistance and strength requirements. Outer surface roughness Ra 0.1 μm or less; inner surface polishable to Ra 0.06 μm or less, minimizing sample residue. Straightness 0.05 mm or less to avoid deflection and jamming in automatic analyzers. Optional PTFE (Teflon) coating (domestic / imported), easy to clean, corrosion-resistant and anti-adhesive. Length, diameter and tip shape customizable to drawing; small-batch trial orders (1–10 pieces) supported. Overseas sales / technical support provided by METICULAB (Korea).

Q: What is the minimum order quantity?
A: Standard products are available from 1 piece. Custom products are evaluated from the drawing; small-batch trial orders (1–10 pieces) are supported.

Q: How long does sampling take?
A: After drawing confirmation, sampling typically takes 30+ working days, depending on complexity.

Q: What is the lead time?
A: In-stock items can be shipped within 1 week. Custom samples and production orders typically require 30+ working days. The above lead time is factory lead time and does not include international shipping time. Adjusted according to quantity and specifications.

Q: How do I choose the coating?
A: Imported coating offers higher wear resistance; domestic coating is more cost-effective. We can recommend based on your environment and budget.

Q: Can you provide material certificates?
A: Yes. Batch material certificates are available, and complete inspection reports can be provided for volume orders.

Q: How do I send my drawing?
A: You can send PDF or CAD files by email or WhatsApp; we will review and reply within 24 hours.
