Precision in Every
Injection

INJ came to this world with a simple goal: to provide researchers and doctors effective solutions that truly make a difference in their mission.

The First System Built for ECG-Platform Injection

Developed by Dr. Kain and Dr. Dagan, INJ is the first tail vein injection system designed specifically for mice on ECG platforms. It makes intravenous injections fast, accurate, and stress-free.

The system stabilizes the tail, instantly reveals the vein, and enables anyone to achieve precise and repeatable injections. Built for preclinical researchers, INJ improves data reliability, reduces operator variability, and saves valuable lab time.

One of our core missions is to bring systemic tail vein injection to the masses — making what was once a technically demanding procedure accessible to every researcher, from seasoned technicians to students doing their first injection.
