Ntega Vita




The integrating of the inverted microscope objective into the central base becouse of high mechanical rigidity provides stability of the system making quality images and long-term experiments possible. Inverted optical microscope stability is not so important any more.

Product Features

  • Different liquid cells are available: hermetic chemically stable liquid flow cell with a possibility of the temperature control at elevated temperatures; closed liquid flow temperature controlled cell for operating with Petri dishes; replaceable heater.
  • Hermetic liquid cell (MP4LCNTF)
    - Flow-through possibility and heating (up to 60oC stability ~0,05°C)
    - Control and changing of biochemical environment in solution during measurements
    - Range of sample positioning 1x1 mm, positioning resolution 5 um.
    - Chemically stable materials (stainless steel, fluoroplast) allow operation in aggressive solvents such as H2SO4, HCl.
  • Quasi-hermetic liquid cell for Petri dishes (MP5LCNTF)
    - Flow-through possibility and heating up to 50°C.
    - Range of sample positioning 1x1 mm, positioning resolution 5 um.
    - Removable heater for the separate cleaning. The heater and the temperature control sensor are located inside the fluoroplastic tube.
    - Changeable probe holder with a glass prism and a silastic membrane
