High Flow Aspiration and Injection Needles

The 18g needle is an indispensable device for efficient medication preparation and rapid fluid transfer in clinical settings. The wide bore size of this gauge is essential when working with viscous medications or when rapid aspiration is required, significantly minimising the time spent drawing up solutions compared to smaller gauge alternatives.

This specific gauge is internationally recognised by its distinctive red needle hub, allowing for fast, error-free identification in busy clinical environments. We carry red needles by trusted brands, including Agriject. Each needle in this collection is manufactured with a sharp, precision-ground bevel to ensure smooth operation and reduced friction.

Frequently Asked Questions

Are the 18g needles in your collection colour-coded for easy identification?

▼

Yes. We stock 18g needles that feature the internationally recognised red hub. This colour-coding allows healthcare professionals to quickly and accurately identify the 18 gauge size in a busy clinical environment, helping to prevent dosing or preparation errors.

What is the difference between an 18G blunt fill needle and a sharp needle?

▼

The primary difference is the tip design. 18G blunt fill needles (often red) feature a non-sharp tip designed to draw up medication from vials without the risk of accidental needle-stick injuries or 'coring' the rubber stopper. 18G sharp needles are designed for penetration and are typically used in veterinary medicine or specialised clinical procedures where a wider gauge is necessary for injection.

Do you carry blunt drawing-up needles in your 18g red needle range?

▼

Yes. Our collection features several blunt-fill options. These are essential for safely drawing up medications from vials while reducing the risk of accidental needlestick injuries.

Are 18G needles suitable for thick or oil-based medications?

▼

Yes, the 18G needle is one of the most effective sizes for handling viscous or oil-based solutions. Because the internal diameter is wider than higher-gauge needles (like 21G green needles), it experiences less resistance. This makes it the standard choice for drawing up thick medications efficiently before switching to a finer needle for the actual injection.
