X-ray irradiators for cells

Two CIX2 X-ray cabinets from Xstrahl have been acquired. One is localised at Campus Solna and one at Campus Flemingsberg. They are 220kV self-contained cabinet irradiators.


Irradiation of biological material using an X-ray machine. The primary use of the irradiator is to irradiate cultured cells suspended in cell culture medium in 15 ml and/or 50 ml centrifugation tubes or growing in tissue culture vessels as a mono-layer in sizes up to 175 square-centimeter cell culture bottles or different type of multi-well plates i.e. 6-well up to 384-well plates.
