X-RAD 320 Biological Irradiator

AHCMCC2 - Image - 250x232 - X-Rad UserThe X-RAD 320 is a self-contained X-ray system for delivering a precise radiation dosage to specimens in a biological or small animal research laboratory.

The shielded cabinet includes an Adjustable Specimen Shelf, Sample Viewing Window and Beam Hardening Filter Holder.

The X-RAD Control Panel is a multilanguage selectable graphical interface with all x-ray parameters and system status clearly displayed.

Programmable exposure settings allow for fast and repeatable exposure setup.

The X-ray tube is used specifically for radiation therapy having a highly homogenous beam.
