NPD Insect Growth Chamber
Model NPD-242 | Controlled Insect Rearing, Breeding & Entomological Research
The NPD-242 provides controlled temperature, humidity, airflow and light/dark cycles for repeatable insect-rearing and laboratory studies. Designed for insectaries and research on mosquitoes, beetles, moths, Drosophila and other insect colonies.
Precise Insect Rearing & Environmental Research
The NPD-242 Insect Growth Chamber is built for life-cycle observation, insect breeding, behavior studies and other entomological research that requires controlled environmental conditions. Programmable temperature, humidity and photoperiod functions help laboratories maintain species-appropriate rearing environments.
Horizontal airflow distributes conditioned air across shelf positions. The interior uses Type 304 stainless steel with a 2B finish, while the powder-coated steel exterior and CFC-free PUF insulation support durability. Coated refrigeration coils are intended to resist the corrosive conditions associated with insect cultures.
Lighting and humidity settings can be selected around a study's protocol. The supplied document cites 27°C, 80% RH and a 12:12 light/dark cycle as an example used for some mosquito colonies—not a universal setting for all species.
