// WHY CHOOSE INJ
4 Pillars of Precision
Engineered for the exact demands of preclinical research labs.
Vein Visualization
Focused illumination and tail-guiding groove enable unmatched visibility of the lateral vein even in dark-coated mice (C57BL/6), ensuring accurate and stress-free injections every time.
Injection Precision
INJ's ergonomic catheter holder and fine-gauge compatibility (27–30G) provide full control during every procedure, reducing resistance, tissue trauma, and injection variability.
Temperature Stability
Integrated warming and anesthesia stabilization maintain optimal body temperature and vein dilation, helping researchers achieve consistent results while protecting animal welfare.
Reproducibility & Compliance
Developed with IACUC standards in mind, INJ combines precision technology with ethical research practices, empowering scientists to produce reliable, reproducible data.
// OUR PRODUCTS
Engineered for the Lab
INJ ECG Tail Injector
The first and only injection system designed to mount directly onto ECG imaging platforms. Enables accurate, repeatable injections without interrupting imaging — compatible with VisualSonics Vevo series.
INJ Bench Tail Injector Restrainer
Designed to make tail vein injections in awake mice easy, fast, and controlled. The mouse enters independently — no force needed. Backlit tail groove reveals the vein instantly for precise, repeatable injections.
