Rat Rotating Restraint Device

Reliable Restraint for Accurate Small Animal Research

The Broome-type Rat Rotating Restraint Device is a precision-engineered system designed to provide secure, stable, and low-stress immobilization of rats during laboratory procedures. Developed using advanced CAD design and manufactured through high-resolution 3D printing with durable biodegradable PLA+, the device ensures reliability, accuracy, and ease of use in modern research environments.

Optimized for minimally invasive and non-invasive applications, the system allows researchers and clinicians to perform procedures such as intravenous injections, blood sampling, blood pressure monitoring, and temperature measurement without the need for anesthesia. Its ergonomic cylindrical design ensures proper positioning of the animal while maintaining comfort, airflow, and full procedural access.

The modular architecture enables fast setup, easy adjustment for different rat sizes, and efficient cleaning or component replacement, making the device ideal for routine use in biomedical, and academic research laboratories.

Key Features

Adjustable Animal Positioning

A conical movable plunger with integrated head support allows precise adjustment for rats of different sizes, ensuring secure yet gentle restraint.

360° Rotating System with Automatic Position Locking

The integrated rotation mechanism enables full 360-degree positioning, allowing optimal access to the tail veins and improving procedural efficiency. The working position automatically locks during rotation, ensuring maximum stability and precise control throughout handling and procedural workflows.

Sliding Entry Door System

A TPU 95 sliding door allows quick and safe placement of the animal, featuring a dedicated tail exit opening to enhance comfort and reduce stress.

Secure Cylindrical Chamber

The cylindrical body design minimizes unwanted movement, protecting both the animal from injury and the handler from bites or scratches.

Optimized Ventilation Design

Perimeter ventilation openings combined with a ventilated nose section ensure continuous airflow and improved animal welfare.

Stable Anti-Slip Base

A TPU 95A base provides strong grip on work surfaces, while an optional version with neodymium magnets enables secure positioning on metallic benches.

Durable, Eco-Friendly Construction

Manufactured from high-strength biodegradable PLA+, offering durability while minimizing environmental impact.

Modular & Easy-to-Maintain Components

All moving and adjustable parts are modular and replaceable, supporting long-term use and simplified maintenance.

Rodent Restrainers and Recommended Body Weight Ranges

Each restrainer size corresponds to specific animal body weight ranges in order to ensure proper fit, animal welfare, and procedural accuracy.

  • The above weight ranges are indicative and may vary depending on animal strain, body composition, and specific experimental requirements. In practice, restrainer dimensions often support overlapping body weight ranges.
  • The dimensions of the devices (restrainers, anesthesia masks, etc.) can be customized upon special order according to the customer’s requirements.
