Ideal for larger cell cultures and small animal applications

A compact, fully-shielded, self-contained x-ray irradiator that can be used almost anywhere, by anyone.

The MultiRad225 is a high power research platform used for cell and tissue cultures and ideal for targeted irradiation of small animals.

Offering a range of options, including programmable motorized shelf for infinitely variable SSDs. The system is cost effective and free of costly licensing, security and source maintenance fees, which provides a much lower cost of ownership than competitive products.
