NEW CRYOSTAT MICROTOMEThe AO CRYO-CUT Adds New Comfortand Convenience to Frozen Sectioning

The newAO SpencerCRYO-CUT Microtome offers

many exclusive performance and convenience fea-

tures to make frozen sectioning easier, more routineand more precise than ever before possible. Fresh

tissue to finished slide takes only a few minutes and

the time-proved mechanism of the AO RotaryMicrotome assures uniform, undistorted sectionsfor more definitive pathologic diagnosis.You can sit down comfortably at the new CRYO-CUT. There's plenty of leg and foot room. The

feed and cutting controls are both external and

within easy reach. Convenient external temperaturesettings let you select operating temperatures within

range of -10' to -30°C. A completely automatic

control unit maintains the selected temperature to

within +1'C.A unique anti-roll device provides flat, uncurledsections for quicker, easier sectioning and mount-ing. A clear plastic breath shield prevents specimenwarming or frosting of specimen and knife to assuremore efficient sectioning.Easily accessible valve allows rapid defrost. A

convenient drain is in front of unit and accommo-dates a disposable plastic bag for catching water and

waste materials.There are many more outstanding performance and

safety features. Write for complete information or askyour AO Sales Representative for a demonstration.
