‘For the first time, high laser power and high repetition rates, are combined within one system,’ Leica Microsystems explains. ‘The laser’s high pulse repetition rates are ideal for the fast excision of single cells, cell clusters, or thin and soft samples. Additionally, high laser power allows the dissection of thick or hard specimens.’
The new Leica LMD6500 and LMD7000 laser microdissection systems both use gravity to collect samples. ‘The dissected material, whatever its size or shape, is collected in a contact-free, contamination-free manner. No additional procedures are necessary for collection.’
The laser beam movement of the Leica LMD7000 and LMD6500 is controlled by high precision optics, whereas the microscope stage and the sample are both fixed. ‘This allows precise cutting accuracy at high magnifications, as well as high cutting speed at low magnifications. Both are prerequisites to obtain homogeneous material for downstream analysis and reliable results.’
Leica Microsystems’ new, intuitive, user interface eases everyday research, the manufacturer reports. ‘Additional consumables, such as a non-fluorescent, glass-like membrane for all contrast methods, complete the extensive consumables programme.’
The company also adds that these new systems are ideal for biomarker research, molecular pathology, and many more applications..
