Thermo Scientific Forma Vertical Light Chambers

Thermo Scientific Forma Vertical Light Chambers address a variety of applications that require sample exposure in light, along with temperature control.

Key Features

  • Solid door is supplied as standard
  • Height adjustable vertical light modules allow flexibility to maintain distance between samples and light, for a wide range of sample volumes
  • Optimal conditions can be achieved through a choice of light settings. Wide light distribution is achieved with 7 light bulbs
  • Three different light modules are available to address applications

    • ICH stability testing: addressing light and UV exposure according to guideline Q1B
    • Plant Growth: addressing high red/blue radiation for optimal growth conditions
    • Animal hatching: providing daylight simulation

  • Program light cycles:

    • Day/night or individual on/off cycles for every day of the week
    • Dawn/dusk simulations with increasing intensity in 3 steps

  • Light modes can be active or inactive, making the chambers suitable for non-light applications, using temperature and humidity controls only
  • Install up to 3 light modules without humidity control or 2 light modules with humidity control in the large unit (waterproof special electrical connectors are provided)
  • Install up to 2 light modules in the small unit (waterproof special electrical connectors are provided)
