The Yamato IC-403CW is a 97 L natural-convection general purpose incubator with a front observation window (the "W" variant) so cultures can be checked without opening the outer door. It holds set points from room temperature +5 °C to 80 °C with ±0.5 °C control accuracy at 37 °C, using air-jacket heating for gentle, even distribution. A reinforced-glass inner door lets you inspect contents while preserving the internal atmosphere.

Application Profile
Natural-convection incubators like the Yamato IC-403CW warm samples through air-jacket technology rather than a fan, heat rises gently around the chamber, avoiding the air currents and evaporation that forced-convection units introduce. That makes the IC-400 series a good match for microbiological culture and general sample incubation where a still, uniform 37 °C environment matters more than fast recovery.
The defining feature here is visibility. The observation window and reinforced-glass inner door form a dual-door system, so you can view plates and flasks without breaking the incubator's atmosphere. At 97 L the IC-403CW sits mid-range, larger than the benchtop 37 L IC-103C, smaller than the 159 L, 318 L, and 567 L models. Standard functions include self-diagnostics, calibration offset, overheat prevention, and key lock, plus a digital timer with auto-start/auto-stop.
Frequently Asked Questions
What does the "W" in IC-403CW mean? It denotes the observation window. Per Yamato's model guide, the IC-403C is the standard 97 L unit; adding W gives the front viewing window, while adding R would add a communication port.
How large is the usable chamber? Internal dimensions are 450 × 480 × 450 mm for a 97 L capacity, with 9 shelf-rest steps and roughly 15 kg load capacity per shelf. Temperature holds ±0.5 °C at 37 °C across a room temp. +5 °C to 80 °C range.
What voltage does it ship as? The IC-403CW is rated AC115V 4.5A with plug. A 220V configuration (AC220V 2A) exists in the same model column. Confirm 115V vs 220V at order.
Ordering & Configuration
Add the IC-403CW to a quote to confirm supply voltage (115V vs 220V), stand or stacking-kit needs, and any optional shelves, cable ports, or communication port.
Warranty: Per Yamato standard terms. Confirm coverage at quote. Lead time and freight confirmed at quote (~45 kg).
Choosing within the IC-400 range: the IC-403CW adds an observation window for at-a-glance checks; the IC-403C is the same 97 L chamber with a solid door. Step up to the 159 L IC-603 or 318 L IC-803 for larger batches; pick the window (W) variant to view cultures without opening the chamber.
