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.
