INJ Bench Tail Injector Restrainer

Effortless Injection for Awake Mice

The INJ Bench Tail Injector Restrainer is designed to make tail vein injections in awake mice easy, fast, and controlled. The mouse walks in independently through the built-in channel — no pushing or forcing is needed.

Once positioned, the restrainer locks securely, the tail is aligned over the backlight for clear vein visualization, and the injection angle can be fixed for a stable and repeatable injection experience.

Components are made from durable, autoclavable materials. The system is reusable after proper cleaning and sterilization following standard lab protocols.

Three Steps to a Perfect Injection

Mouse entering INJ bench restrainer tunnel

01

Tunnel-Guided Self-Entry for Stress-Free Positioning

The built-in tunnel allows the mouse to enter the restrainer independently, without handling pressure or force. This reduces stress, improves cooperation and creates a smoother workflow during tail-vein procedures. The result is faster setup, better animal welfare and a more consistent injection process.

Precision angle control mechanism

02

Precision Angle Control for Clear Vein Access

The system allows smooth and controlled rotation of the mouse, ensuring optimal alignment for tail vein visualization without unnecessary handling. Once the ideal angle is reached, the position can be locked, providing stability during injection. This improves accuracy, reduces time and minimizes stress for both operator and animal.

Enhanced Backlit Vein Visibility

The integrated backlight illuminates the tail from below, making the vein clearly visible and easy to locate. This reduces guesswork and improves accuracy, even with less experienced operators. The result is faster injections, fewer attempts and a more consistent workflow.
