The Yamato IC-903CW is a 567 L large-capacity natural-convection incubator with an observation window and twin reinforced-glass inner doors, holding room temperature +5 °C to 80 °C at ±0.5 °C control at 37 °C. The Yamato IC-903CW brings the IC series' gentle, fan-free air-jacket heating to a floor-standing cabinet with a two-column, 29-step shelving layout, so a lab can incubate a large sample load at a tightly controlled temperature. It is the top of the general-purpose incubator range for high-volume microbiology, sample conditioning, and constant-temperature work. It is the 115 V model; the 220 V sibling is the IC-913CW.

Application Profile
The IC-903CW is the high-volume member of the IC general-purpose incubator line. A 567 L, floor-standing cabinet that holds a large sample load without giving up the gentle natural-convection, air-jacket heating that defines the series. That combination of scale and fan-free uniformity (±1.0 °C distribution, ±0.5 °C at 37 °C) suits shared microbiology facilities, large culture programs, sample conditioning, and any constant-temperature workflow up to 80 °C where many samples must be held identically (see incubator-selection).
Two reinforced-glass inner doors partition the wide chamber, so a technician can open one side of the cabinet to load or read a shelf while the other side's atmosphere stays largely undisturbed, a real reproducibility benefit when a big incubator is opened repeatedly through the day. The two-column, 29-step shelving accepts eight shelf plates as standard and organizes a dense load. As a ~166 kg floor unit drawing 13 A, it needs a dedicated 115 V circuit and floor clearance, which are part of the specification conversation.
Frequently Asked Questions
What is the capacity and temperature range of the IC-903CW? 567 L, room temperature +5 °C to 80 °C, with ±0.5 °C control at 37 °C and ±1.0 °C distribution.
How is the chamber organized? Two shelving columns with 29 positions each; eight stainless shelf plates and sixteen brackets ship standard, each shelf rated ~15 kg.
What do the twin inner doors do? The dual reinforced-glass inner doors let you access one side of the cabinet while limiting disturbance to the other side's temperature and atmosphere, useful for high-traffic shared use.
Is it forced-air? No, natural-convection, air-jacket heating, which keeps airflow from drying open plates or disturbing samples even at this size.
What power does it need? AC115V, 13 A, with plug. A dedicated 115 V circuit is recommended. The 220 V sibling is the IC-913CW.
Ordering & Configuration
quote-based. The IC-903CW is a large-capacity floor-standing incubator sold through a quote. At quote we confirm 115 V service and circuit, floor space for the 1180 × 656 × 1619 mm, ~166 kg cabinet, additional-shelf needs, and options such as cable ports or output terminals. Warranty terms are confirmed with the quote, and lead time is provided at quotation. Request a quote to configure the IC-903CW for your facility.
IC general-purpose incubator, by size and voltage: the IC-903CW (this unit, 567 L, 115 V, twin inner doors) is the largest in the range; the IC-913CW is its 220 V sibling. Step down to the IC-603CW (159 L) or benchtop IC-103CW (37 L) for smaller loads. Choose the IC line for gentle natural-convection incubation; choose a forced-convection oven when you need rapid, uniform high-temperature processing.
