2 CHAMBER FEATURES
2.1 Configurations
The base GEN1000 chamber can be fitted with any of the following specially configured kits and
each kit is also available with an LED lighting option:
•The Short Plant (SH) kit is a two-tier, or an SH-XTIER three-tier configuration, that uses
horizontal airflow over multiple shelves optimizing the growth area for shorter plants, like
Arabidopsis. Ideal for research in propagation, genetics, physiology, and other moderate
light experiments.
•The Tall Plant (TA) kit is a single-tier configuration that provides upward airflow,
maximum growth height, and light intensity for taller plants such as cereal crops,
horticultural plants, and silviculture.
•The Tissue Culture (TC) kit is a four-tier configuration that uses low light to maximize
space. It also provides upward airflow minimizing condensation in petri dishes and jars
used in propagation and genetics experiments.
•The Incubator (IN) kit is a four-tier configuration that uses horizontal airflow and low light
levels optimizing the incubation of plantlets and insects.
2.2 Control System
The control system provides advanced programming capabilities, allowing ramping or stepping
of environmental conditions to match research requirements. User programmable ″set and
forget″alarms track the chamber operation relative to user-defined setpoints. Visual and audible
notifications provide a further level of protection. For remote monitoring and control, the
chamber comes ready to communicate with Conviron’s Central Management™ or CMP-Link.
Refer to the included Conviron CMP6060 Operator’s Manual for complete instructions.
2.3 Air Intake and Exhaust
Air inside the chamber is exchanged through manually adjustable fresh-air and exhaust ports.
2.4 Humidity Control
Additive humidity is controlled through the use of an ultrasonic humidifier. Based on +21°C
(70°F) and 50% RH ambient conditions, a range of up to 90% RH with the lights off and 75%
with the lights on, limited by a +25°C (77°F) dew point.
The stated humidity range is for an empty chamber. The chamber may achieve higher
humidity levels with plant loading.
