vertical-light-chambers

Vertical Light Chambers address a variety of applications that require sample exposure with light, along with temperature control and humidity.

  • Flexible set up addresses requirements for sample distance to light and sample volume
  • ICH light module for optimal light exposure according to guideline Q1B. Order desired number of modules separately
  • Specific light modules for plant growth and animal hatching also available
  • Solid door ensures there is no "light pollution" in the light exposure to samples

Address applications under optimal conditions with light choices. Wide light distribution is achieved with 7 fluorescent light bulbs.

Please refer to the following charts for temperature and humidity levels with light on. For broader temperature and humidity range, please use only one module in the chamber.

Plant Growth
plant-growth

The light modules for plant growth have light bulbs that emit increased red and blue wavelengths based on typical sunlight patterns, which are beneficial for plant growth. Install up to 3 light modules in the large unit (water-proof special electrical connectors are provided).

Insect / Animal Hatching
insect or animal hatching

The light modules for insect hatching have bulbs that mimic daylight – ideal for the required day/night simulation. A dusk/dawn feature enables a progressive program that simulates the rising and setting sun, switching on and off in three steps. This helps prevent stress to insects and animals from sudden high-light exposure.

Light Stability Testing
Light stability testing

A typical process to expose the samples with at least 1.2 million lux hours and 200 watt hours/square meter of UV-light will take less than 170 hours. Such a cycle can easily be programmed: The light will switch off automatically as the specified exposure time is reached.

Tip: For safety reasons we offer an additional “light protection” feature when following ICH testing guidelines. With this added, the light will automatically switch off as the door is opened, helping to prevent UV light exposure as it can be detrimental to the operators’ eyes. Special UV-googles are an alternative approach.
