FAQ:

Q1: What are the standard dimensions and customization ranges?

A: Standard dimensions: needle length 50–100mm, needle diameter Φ0.5–Φ1.0mm, side-hole diameter 0.1–0.3mm, yellow Luer connector hub. Customizable ranges: needle length (20–200mm), needle diameter (Φ0.3–Φ1.2mm), number of side-holes (single/double), side-hole angle (15°–45°), interface type (Luer/threaded/quick-plug), plastic hub color/shape, etc.

Q2: What are the advantages of the side-hole design? How is it different from a normal straight-hole needle?

A: The side-hole design allows liquid to flow out from the side of the tip, avoiding damage or splashing caused by the "vertical impact" of straight-hole needles (e.g., to cells, gels); it also reduces the "adsorption effect" of the tip, improving the transfer accuracy of μL-level samples. Normal straight-hole needles tend to cause sample residue, cross-contamination, and have poor compatibility with fragile samples (e.g., cell suspensions).

Q3: What IVD scenarios is this needle suitable for? Can it be compatible with other devices?

A: Suitable for μL-level sample handling (e.g., reagent aspiration in biochemical analyzers, sample dilution in immunoanalyzers, rapid testing in POCT devices), cell/tissue puncture (e.g., flow cytometry sample preparation), high-viscosity reagent transfer (e.g., protein electrophoresis aspiration), etc. Customizable interfaces (e.g., Luer connector, threaded, quick-plug) ensure compatibility with most IVD instruments (e.g., devices from Roche, Abbott, Mindray, etc.).
