Heat Up Transition Time* 5°C per minute typical
*Note: Transition times are measured after a 1 hour soak at the respective start temperature with an empty chamber,
as indicated on the temperature controller, 23°C ambient. Measured with set point beyond the start and end
temperatures. Does not include the effect of proportional band when approaching set point. Measured at nominal
line voltage of 120V, 60 Hz.

the floor, in a free-standing environment)
NOTE: Performance is typical and based on operation at 23°C (73°F) ambient and nominal input voltage. This
product is designed for use in a normal conditioned laboratory. Operation at higher ambient temperatures will result
in decreased cooling performance. Additional ports and shelves will also affect performance. Operation above 30°C
(85°F) or below 16°C (60°F) ambient is not recommended.
