Live Cell Imaging In Your Incubator

Live Cell Imaging In Your Incubator

With Etaluma’s high resolution, versatile, and compact inverted LS Microscopes that actually fit inside your incubator, you get stable temperatures and CO2 levels throughout your assays.
  • Quality comparable to traditional, high-cost microscopes
  • Compatible with microplates, dishes, chamber slides, flasks, microfluidic chips
  • 3-Color fluorescence, phase contrast, brightfield
  • Images, time-lapse & live video
  • 1.25-100x objectives
  • LS720 pictured above with phase contrast: Auto XY stage & autofocus








LS620 Microscope
Blue, Green & Red Fluorescence with Manual Stage
LS Microscopes (previously called Lumascopes) utilize LED light sources, Semrock filters, advanced optical engineering, and CMOS sensors to provide near diffraction-limited (theoretical maximum) resolution. Powered only by its USB connection, the LS620 easily records your photos, time-lapse series, and videos directly to your computer. And its compact size enables working in challenging locations, including inside incubators, biological safety cabinets, and environmental control workstations.
LS620
LS720 Microscope
Blue, Green, & Red Fluorescence and Walk-Away Automation
The powerful, new LS720 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 HCS systems. Whether imaging multiple fields in your flasks or 1536 wells of cells with 3 fluorophores in a 48 hour time-lapse, the 720 offers a whole new world of automated microscopy!
LS720
Features 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
Both utilize 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 that is larger than the sensor used in LS500 and LS400.
