CO2 Incubator Water Jacket Temperature Control

Precise Uniformity

Water Jacket Temperature Control

In-VitroCell Water Jacket CO2 Incubators maintain accurate temperature with the large 18 gallons (68.1-liter) water jacket that surrounds the inner chamber. Heated water in this jacket circulates around the growth chamber, keeping the temperature uniform within the growth chamber ±0.2°C. Precise temperature control is aided by the R5 insulation that lines the outer chamber walls that minimize heat loss.

The door and perimeter heaters are microprocessor-controlled to adjust to the room's ambient temperature. They can also be adjusted manually from ±20 percent to reduce condensation within the growth chamber.
