Confocal Microscopy

LSM900 Inverted

The Zeiss LSM900 Inverted confocal laser scanning microscope comprises an inverted Zeiss Axio Observer 7, four laser lines, two GaAsP-PMT detectors, and a motorised stage. The microscope is easy to use and allows high-quality multicolour imaging, thus perfect for classic laser scanning confocal microscopy (CLSM).
