Laser Microdissection Microscope

Laser microdissection offers researchers a tool for precise non-contact and contamination-free preparation of cell groups or single cells cut out of histological tissue sections.

The Leica Laser Microdissection Microscope – ASLMD uses the DMLA upright Leica microscope including motorized nosepiece, motorized stage, the xyz-control element and all other advantages of the new DMLA microscope. The laser used is a UV laser of 337 nm wavelength. The movement during cutting is done by the optics, while the stage remains stationary. The region of interest can be marked on the monitor and is cut out by PC control. The sample falls down into PCR tubes without extra forces. The result of the cutting can be easily checked by an automated inspection mode.

Leica AS LMD Overview

Laser microdissection has established itself as a powerful technology essential to a range of downstream applications in pathology, cancer research, life sciences, medical diagnostics and biotechnology.

The Leica AS LMD offers a powerful tool for contamination free separation of cells or cell groups in preparation for PCR, RT-PCR and Proteomics, to name a few.

The Leica AS LMD, a "third-generation" micro-dissection platform, was developed combining automated upright microscope architecture, three-dimensional optical control of the dissecting laser beam and the dissected area, non-contact tissue sampling and motorized post-dissection handling
