[100s] NIPRO Hypodermic Needle 18G x 1.5" (38mm) | Thin Wall Drawing Needle | Sterile | Pink Hub EMIS+

Product Overview

NIPRO Hypodermic Needles are manufactured by NIPRO Corporation (Japan), one of the world's largest medical device manufacturers producing over 11 billion needles annually. The 18G x 1.5 inch (38mm) thin-wall variant is engineered for clinical applications requiring high flow rates, including aspiration of viscous medications from vials, reconstitution of lyophilised drugs, drawing blood samples, and intramuscular injection of oil-based preparations. The thin-wall design maximises the internal lumen diameter while maintaining the standard 18-gauge outer diameter (1.20mm), resulting in faster fluid transfer and reduced aspiration time compared to regular-wall needles.

Each needle undergoes automated electro-polishing and silicone coating of the cannula surface to minimise insertion friction and tissue trauma. The tri-bevel lancet point geometry is precision-ground to ensure clean tissue penetration with minimal coring. The pink colour-coded polypropylene hub conforms to ISO 6009 international colour coding standards for needle gauge identification, and features a female Luer-lock fitting compatible with all standard Luer-lock and Luer-slip syringes. Packaged in individual peel-open blister packs, each box contains 100 sterile needles suitable for hospital pharmacy, ward stock, and clinic dispensary use in Singapore.

Specifications

Clinical Indications

• Aspiration of viscous medications, reconstituted biologics, and oil-based preparations from vials and ampoules where standard-wall needles provide insufficient flow rates
• Intramuscular injection of depot formulations, vaccines, and medications requiring deep tissue delivery via the deltoid, vastus lateralis, or gluteal sites
• Blood specimen collection for laboratory analysis when vacuum tube systems are not available or appropriate
• Reconstitution of lyophilised medications requiring rapid solvent transfer through large-bore needle access
• Fluid aspiration in minor clinical procedures including abscess drainage and joint aspiration under physician supervision
• Medication preparation and drawing-up in pharmacy compounding and ward-level drug preparation

Frequently Asked Questions

What is the advantage of thin-wall over regular-wall construction in 18G needles?

Thin-wall construction maintains the same 1.20mm outer diameter as standard 18G needles while reducing the cannula wall thickness, resulting in a larger internal lumen. This provides approximately 20-30% faster flow rates compared to regular-wall needles of the same gauge, which is clinically significant when aspirating viscous medications, blood products, or reconstituting lyophilised drugs. The external gauge remains identical, so tissue penetration characteristics and patient comfort are equivalent to standard-wall needles.

Why is the hub colour-coded pink for 18G needles?

The pink hub colour follows ISO 6009 international standards for hypodermic needle gauge identification. This standardised colour coding system enables rapid visual identification of needle gauge in clinical settings, reducing medication administration errors. Healthcare professionals can immediately confirm the correct gauge selection during medication preparation without reading printed text, which is particularly important in emergency and high-acuity care environments per WHO injection safety guidelines.

Are NIPRO needles compatible with all standard syringes?

Yes. The female Luer-lock hub is manufactured to ISO 594-2 and ISO 80369-7 standards, ensuring universal compatibility with all standard Luer-lock syringes. The hub also fits Luer-slip syringes, though Luer-lock connection is recommended for secure attachment during aspiration of viscous fluids where disconnection under pressure is a risk. NIPRO needles are compatible with syringes from all major manufacturers including BD, Terumo, and NIPRO.

What sterilisation method is used and how long is the shelf life?

NIPRO hypodermic needles are sterilised using ethylene oxide (EO) gas sterilisation, a validated low-temperature method suitable for heat-sensitive medical devices. Each needle is individually sealed in a peel-open blister pack that maintains sterility for 5 years from the date of manufacture when stored in the original packaging at room temperature, away from moisture and direct sunlight. The sterilisation process and validation comply with ISO 11135 requirements.

Can these needles be purchased by healthcare facilities in Singapore?

Yes. NIPRO Hypodermic Needles are HSA Singapore Class B registered medical devices available for purchase by licensed healthcare facilities, clinics, and pharmacies through EMIS+. The product is CE marked under EU MDR 2017/745, FDA 510(k) cleared, and manufactured in ISO 13485-certified NIPRO facilities. Bulk ordering for hospital and clinic procurement is available with delivery throughout Singapore.
