TAOMSUN slotted piercing needles and tubular stainless steel custom parts are designed for laboratory analytical equipment, suitable for piercing laboratory reagent bottles. The slot structure effectively relieves pressure and vents air, preventing negative pressure or splashing during piercing. Materials optional SUS304 / SUS316L, corrosion-resistant with high strength. Slot width × depth customizable per drawing, finish Ra 0.2; outer surface roughness Ra 0.1 μm or less; inner surface polishable to Ra 0.06 μm or less; straightness 0.05 mm or less, ensuring accurate piercing position. Optional PTFE (Teflon) coating, anti-adhesion and easy to clean. Trial orders of 1–10 pieces supported, custom machining per drawing, stable lead time. This product is a laboratory equipment component for laboratory use only. Overseas sales / technical support provided by METICULAB (Korea).
