Sterile 14 Gauge 1.5 Inch Luer-Lok Needles (10 Pack)

Title: Sterile Needle 2.0*40mm (Luer) 14G x 1 1/2″ – 10 Pack

Description:

This listing features a 10-pack of sterile, disposable 14G (2.0 x 40mm) injection needles with Luer fitting. These needles are essential for local anesthesia, precisely delivering solution from a carpule into the surrounding tissue. Key components include a metallic tube (cannula), a Luer adapter for syringe connection, and a beveled tip for smooth penetration. Some manufacturers include a bevel indicator for accurate tissue insertion.

Needle selection depends on two primary factors: gauge (diameter) and length. International standards define these dimensions, with manufacturers often categorizing needles as long, short, or very short, often color-coded on packaging. Length is measured in both inches and millimeters.

Gauge (G) refers to the inner diameter of the needle; a higher gauge number indicates a smaller inner diameter. This is analogous to camera aperture; a higher f-stop number denotes a smaller aperture. The relationship between gauge and inner diameter isn’t linear, as it’s based on the cross-sectional area.

While the outer diameter is more intuitively understood, it’s not standardized across manufacturers due to variations in cannula wall thickness. Therefore, the correlation between gauge and outer diameter is approximate, although both are typically indicated on product packaging. This pack provides reliable, high-quality needles for precise and efficient injections.
