Humaneway™ Laboratory Needles
Ultra-sharp 25G disposable needles designed for laboratory mice and rats. The line includes Blood Collection Needles (50/box) for closed-system capillary-action sampling via 1.8mm tubes, and Winged Infusion Sets (100/box) with flexible butterfly wings for precise tail vein injection. Compatible with Humaneway™ Tail Vein Simulators for training.
What are the Humaneway™ Laboratory Needles?
The Humaneway™ Laboratory Needle line includes Blood Collection Needles and Winged Infusion Sets specifically designed for use with laboratory mice and rats. These ultra-sharp 25G disposable needles minimize tissue damage and animal discomfort, ensuring reliable and consistent blood samples and intravenous access during research procedures.
The Blood Collection Needles connect to 1.8mm (±0.1mm) capillary tubes for closed-system blood sampling via capillary action, improving sample quality and supporting humane protocols. The Winged Infusion Sets feature flexible wings for easy handling and can connect to any size capillary tubes or syringes, making them the ideal choice for tail vein injection practice with Humaneway™ Tail Vein Simulators.
Key Features
- Ultra-Sharp 25G Needles: Precision-ground tips minimize tissue damage and reduce animal distress during venipuncture procedures.
- Closed-System Blood Collection: Blood Collection Needles enable capillary-action sampling through a closed system, improving sample quality and reducing contamination risk.
- Flexible Winged Design: Winged Infusion Sets feature butterfly wings for stable grip and precise needle control during injection.
- Universal Compatibility: Winged Infusion Sets connect to any size capillary tubes or syringes for maximum versatility.
- Training and Research Ready: Designed for both live animal procedures and practice with Humaneway™ Tail Vein Simulators.

What needles are included in the Humaneway™ Laboratory Needles line?
The line consists of two purpose-built 25G disposable needles for mice and rats: Blood Collection Needles, sold 50 per box, designed for closed-system capillary-action sampling through 1.8 mm tubes; and Winged Infusion Sets, sold 100 per box, with flexible butterfly wings for stable tail-vein injection.
Why 25G specifically for mice and rats?
25G strikes the practical balance for rodent vasculature — small enough to cannulate mouse and rat tail veins without excessive tissue trauma, large enough to permit reliable capillary blood draw and infusion flow. It is the most widely used gauge in laboratory rodent venipuncture protocols.
How does the closed-system blood collection work?
The Blood Collection Needles connect to a 1.8 mm tube that fills by capillary action, keeping the sample in a closed, contained system from the moment of draw — reducing both contamination and operator exposure compared with open-needle dripping techniques.
Are the Winged Infusion Sets compatible with the Humaneway™ simulators?
Yes. The Winged Infusion Sets are matched to the Humaneway™ Rodent Tail Vein Simulators for hands-on training, letting new staff develop technique on simulators with the exact consumables they will later use in live animals.
Is local distribution and support available in Israel?
Yes. NBT Ltd is the Israeli distributor of the full Humaneway™ range, supplying needles directly to vivariums, breeding facilities, and research labs across the country with local stock and delivery.
