Refrigerated Incubator Programmable 143L With Window & MK-161 Shaker Overview
Refrigeration runs on a 250 W air-cooled hermetic R134a compressor paired with a 550 W iron-chrome heater. Yamato lists external dimensions (W × D × H) of 710 × 645 × 913 mm (28.0 × 25.4 × 35.9 in); packed for shipping it measures 36 × 36 × 54 in at 332 lb. Voltage options cover 115V and 220V, and the build is backed by ISO 9001:2015 and ISO 14001:2015 certifications.
Key Features
- Triplex glass door: dual outer glass door plus an inner glass door retains heat while allowing direct sample observation.
- Programmable PID control: high-accuracy temperature control with ±0.3°C accuracy and ±1.0°C distribution during continuous operation at 37°C.
- Refrigerated forced convection: air-cooled hermetic R134a compressor (250 W) and 550 W heater deliver a −10 to +50°C operating range.
- Large observation window: W516 × H416 mm viewing window with key for secured access.
- Included MK161 shaker: compact shaker ships with the unit; an optional slide shaker table eases sample loading and removal.
- Stainless steel chamber: stainless interior with manual-ON / auto-OFF defrost, timer, and cycle operation.
How to Choose the Right Incubator
Matching an incubator to your workflow comes down to chamber size, the temperature envelope you need, and how precisely you must hold a setpoint. Use the criteria below to confirm the IN604WMK fits your protocol and site infrastructure.
- Temperature range: the −10 to +50°C span covers low-temperature and ambient-plus testing that ambient-only incubators cannot reach.
- Control type: programmable PID control supports multi-step profiles; choose it when fixed-temperature units leave your protocol underserved.
- Voltage: select 115V or 220V to match your facility's available circuits before installation.
- Footprint and weight: Yamato lists external dimensions (W × D × H) of 710 × 645 × 913 mm (28.0 × 25.4 × 35.9 in); packed for shipping it measures 36 × 36 × 54 in at 332 lb.
- Shaking requirement: the bundled MK161 shaker adds agitation for cultures that need motion without a separate platform.

Frequently Asked Questions
What is the operating temperature range of the IN604WMK?
The IN604WMK operates from −10 to +50°C. Its refrigerated forced-air convection system, driven by a 250 W R134a compressor and 550 W heater, supports both low-temperature and ambient-plus protocols.
What is the chamber capacity and the unit's external dimensions?
Chamber capacity is 143 L. Yamato lists external dimensions (W × D × H) of 710 × 645 × 913 mm (28.0 × 25.4 × 35.9 in); packed for shipping it measures 36 × 36 × 54 in at 332 lb.
What is the difference between the 115V and 220V models?
The only difference is supply voltage. SKU IN-604WMK-115V runs on 115V and IN-604WMK-220V runs on 220V; chamber size, temperature range, control system, and the included shaker are identical. Select the version that matches your facility's circuits.
