Blue, Green, & Red Fluorescence and Walk-Away Automation
Request a Quote!

The powerful, new LS720 Microscope (Lumascope) adds walk-away automation to the many features and high performance of the flagship 3-color LS620. Exquisite XY motion control, motorized focus that allows autofocus and z-stacks, and easy-to-configure software combine to facilitate your microscopy experiments and high content screens. Place the LS720 in your incubator and you have a live cell imaging system at a fraction of the cost of conventional High Content Analysis systems. Whether imaging multiple fields in your flasks or 1536 wells of cells with 3 fluorophores in a 48 hour time-lapse, the LS720 offers a whole new world of automated microscopy!

 

ls720-phase-incub-2402br-178Features and Benefits
  • Automated XY stage with autofocus in Z provides images (photos), time-lapse series, and videos recorded directly to your computer
  • Fully functioning microscope empowers users to visualize cells from microplates, flasks, slides or custom labware
  • Modern LED and advanced optical design provide near diffraction-limited (theoretical maximum) resolution
  • Robust software allows set-up and control across many locations, including microplates and custom arrays
  • Versatile and compact design enables use inside cell culture incubators and hoods
  • Detects blue, green and red fluorophores, including BFP, DAPI, FITC, Fluo-4, GFP & mCherry
  • Flip-up deck allows easy objective access
  • Used manually, but also robot compatible (RS485, RS232, 5V digital interfaces)
  • Objective compatibility with standard lenses permits use of your own objectives

 

Like the LS620, the LS720 utilizes a Semrock Brightline® Pinkel filter set optimized for 405 nm, 488 nm, and 594 nm LED light sources. The 5-filter set is comprised of 3 exciting filters, 1 triple-band emitting filter, and 1 beam-splitting filter. The 720 also contains the same CMOS sensor as the LS620.
