33 gauge, Neuros Replacement Needle, Small Removable Hub, PN: 65461-01 Details

The Neuros Replacement Needle (PN: 65461-01) is a fine gauge 33 G needle engineered for compatibility with Neuros Syringes. Its 76.9 mm stainless steel shaft with a blunt Point Style 3 tip allows for safe, controlled injections, especially in sensitive or small animal models. The Small Hub fits securely at the syringe zero line, significantly reducing dead volume and enhancing dose accuracy. Fine gauge needles are ideal for animal research, as they reduce tissue damage and variability in sample delivery. Each pack contains 6 high-precision needles.

Fine gauge 33 G needle minimizes tissue damage and injection variability during animal procedures

Small Hub RN design ensures zero-line mounting, minimizing dead volume and enhancing dosing precision with Neuros Syringes

Zero-Line Removable Hub for Accuracy

  • The Small Hub RN design ensures secure mounting at the syringe’s zero point, minimizing dead volume and maximizing sample delivery efficiency
  • Removable needles are preferred over luer or luer-lock for precision in low-volume applications

Precision Tip and Animal-Friendly Design

  • The blunt Point Style 3 tip and 33 gauge shaft provide smooth, controlled fluid delivery
  • The fine gauge reduces the injection site diameter, helping to limit tissue damage and improve consistency in animal injections

Instruction

Instructions - Neuros Syringes

The Neuros Syringe accurately dispenses 50 nL to 100 μL of liquid through an ultrafine needle protected by a custom-designed sleeve. Developed specifically for the neurosciences, the Neuros minimizes injection site damage by increasing needle rigidity and delivering a microvolume of liquid to an exact location.
