Humaneway™ Rodent Restraint Devices
Precision-engineered rodent restrainers with a bell-shaped entrance for smooth, stress-free animal handling. Fully autoclavable and available in six sizes — three for mice (Φ28, Φ32, Φ35) and three for rats (Φ47, Φ64, Φ70). Designed for tail vein injections, blood collection, and tail-access procedures with minimal animal distress.
What are the Humaneway™ Rodent Restraint Devices?
The Humaneway™ Rodent Restraint Devices are precision-engineered restrainers designed for smooth, low-stress handling of laboratory mice and rats. Featuring a distinctive bell-shaped entrance, these devices allow animals to enter naturally without injury, reducing handler-induced stress and supporting the 3Rs principles of Refinement in animal research.
Available in six sizes — three for mice and three for rats — the restrainers are fully autoclavable and designed for repeated use. They are ideal for tail vein injections, blood collection, subcutaneous and intramuscular injections, and other tail-access procedures. The restrainers also serve as an essential companion to the Humaneway™ Tail Vein Simulators for realistic training workflows.
Key Features
- Bell-Shaped Entrance: Innovative funnel design allows smooth, stress-free animal entry and prevents injuries during restraint.
- Six Sizes Available: Mice restrainers in Φ28 (15–25g), Φ32 (20–40g), and Φ35 (30–50g); rat restrainers in Φ47, Φ64, and Φ70 for a full range of body weights.
- Fully Autoclavable: Designed for sterilization and repeated use in cleanroom and vivarium environments.
- Tail Access Design: Provides unobstructed access to the tail for injections, blood collection, and other procedures.
- Ergonomic Base: Stable base platform keeps the restrainer steady during procedures, improving handler safety and procedural accuracy.
- 3Rs Compliance: Minimizes animal distress through gentle restraint, supporting Refinement of animal handling techniques.

Research on rodent restraint device design and its impact on animal stress, procedural accuracy, and welfare outcomes in laboratory settings.
What are the Humaneway™ Rodent Restraint Devices used for?
Rigid, transparent rodent restrainers with a bell-shaped entry that guides the animal in smoothly with minimal handling stress. They are designed for tail-access procedures — tail-vein injection, blood collection, and tagging — while keeping the animal calm and the operator's hands free.
What sizes are available and how do I choose the right one?
Six sizes total: Φ28, Φ32, and Φ35 mm for mice (covering juvenile through adult), and Φ47, Φ64, and Φ70 mm for rats (covering young adults through large strains). Matching the restrainer diameter to the animal is the single biggest factor in stress-free restraint.
Are the restrainers autoclavable?
Yes — the restrainers are fully autoclavable, making them suitable for SPF and barrier facilities where everything entering the animal room must be sterilized between uses.
What makes these less stressful for the animal than standard restrainers?
The bell-shaped funnel entry, the smooth transparent material that lets animals see ahead, and the size range that lets each animal be matched to a snug-fit tube. Together these reduce the resistance and panic associated with poor-fit restrainers and lower cortisol exposure for the animal.
Is the product available locally in Israel?
Yes. NBT Ltd distributes the full Humaneway™ line in Israel, including the restrainer sizes and complementary tail-vein simulators and training needles, with local stock for quick delivery to vivariums and research facilities.
