LEEC Plant Growth and Seed Germination Cabinets - 1

Plant Growth/Germination Cabinets LEEC A-PDF Split DEMO Plant growth and germination cabinets are based on the cooled incubators detailed on pages 13 and 14. Day and night conditions are automatically simulated and can be easily programmed. Temperature Control All plant growth cabinets use the same temperature control systems as the cooled incubators on which they are based. Temperature performance can be marginally affected during the “lights on” cycle due to a small amount of heat from the lights radiating into the growth chamber. The temperature is cycled using a 24 hour timer. Chart recorder. Audible alarm. Humidity control. Remote alarm contacts. Additional light available by quotation. Illumination All models are fitted with a digital 24 hour timer to control the day/night cycle of lights on and off. Each incubator door is fitted with one pair of white fluorescent tubes. These give a lighting intensity of approximately 3000 lux on each shelf. For higher lighting intensities and specialised applications, extra lights or UV lamps can be added. All lights are mounted in the outer door which is vented at the top and bottom. This means that the unwanted heat can escape into the laboratory. Cabinets fitted with four or more lights in each door also have a small extract fan in the door to help remove heat. This helps to maintain stable control, especially at lower operating temperatures. High Humidity Models Two models (SL2 & SL3) are sealed chamber versions of models PL2 and PL3 respectively and should be used for high humidity applications.
