Bright 8250 Large floorstanding cryostat

Bright Instruments


Bright Instrument Company specialise in the use of cryostat microtomes to prepare frozen sections for microscopy. The 8250 was developed for applications where these cryostats are simply not large or powerful enough.
The most usual application is in whole body autoradiography (WBA) which is used to trace radio-labelled drugs or other compounds in the frozen bodies of test animals.
There are many other uses of the 8250 cryostat including the fields of anatomy training and outside the biological field for use by material scientists to cut objects as diverse as electrical insulation, timber and plastic automobile chassis joints.
