The SRI21D Diurnal Plant Growth Chamber Incubator from SHEL LAB is a precision laboratory growth chamber designed for plant research and experiments that require a day-night cycle simulation. This unit allows researchers to replicate natural diurnal conditions with controlled temperature and light cycles for accurate, reproducible results.

Equipped with dual-program selector dials, the SRI21D manages two independent temperature settings and corresponding ON/OFF light cycles. For example, it can simulate an 8-hour day cycle at 30°C with light followed by a 16-hour night cycle at 18°C without light, creating realistic environmental conditions for plant growth studies.

Forced air circulation ensures uniform temperature distribution throughout the chamber, while a hermetically sealed compressor maintains stable cooling. The independent over-temperature safety controller and one-amp interior outlet allow safe use of shakers, stirrers, roller bottles, or other laboratory apparatus.

Key Features:

• Day/Night temperature and light control for diurnal cycle simulation

• Microprocessor control with precise temperature regulation

• LED display for setpoint and chamber temperature monitoring

• High and low limit temperature protection for safety

• Interior electrical outlet for lab equipment

• Fan-assisted forced-air circulation for uniform growth conditions

• Hermetically-sealed compressor for stable low-temperature performance

• 24-month limited warranty

Applications:

Ideal for plant growth research, diurnal cycle studies, agricultural experiments, photosynthesis and photoperiod studies, and controlled environment plant testing in laboratory settings.
