Refrigerated Incubator Programmable 143L With Window & Mk-161 Shaker Overview
The Refrigerated Incubator Programmable 143L With Window & MK161 Shaker (IN604WMK) from Yamato Scientific is a forced-air convection refrigerated incubator delivering a 143 L chamber and an operating range of −10 to +50°C. LabSupplies.com supplies this unit as an authorized dealer for low-temperature culture and environmental testing.
A large dual glass outer door plus an inner glass door forms a triplex glazing system that improves heat retention and lets technicians view samples without opening the chamber. Interior surfaces are stainless steel, while the exterior uses chrome-free electrogalvanized steel with a chemical-proof baked finish. Styrene foam insulation and PID control support tight thermal stability.
Refrigeration runs on a 250 W air-cooled hermetic R134a compressor paired with a 550 W iron-chrome heater. Each unit ships at roughly 332 lbs with a 36 × 36 × 54 in footprint and is manufactured in Japan. 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.
- Capacity: a 143 L chamber suits mid-volume culture batches and environmental test loads; verify your sample footprint against the usable interior.
- 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: the 36 × 36 × 54 in, ~332 lb unit requires a reinforced bench or floor space and clearance for the swing door.
- 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. External dimensions measure 36 × 36 × 54 in (L × W × H), and the unit weighs approximately 332 lbs, so plan for a reinforced surface and door-swing clearance.
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.
What materials are used in the chamber and exterior?
The interior chamber is stainless steel. Exterior panels use chrome-free electrogalvanized steel with a chemical-proof baked finish, and styrene foam provides heat insulation.
Does the IN604WMK include a shaker?
Yes. A compact MK161 shaker ships with the incubator. An optional slide shaker table is also available to simplify loading and removing samples.
How precise is the temperature control, and is the unit certified?
Temperature accuracy is ±0.3°C and distribution is ±1.0°C during continuous operation at 37°C, managed by PID control with a Pt100Ω sensor. Manufacturing is certified to ISO 9001:2015 and ISO 14001:2015.
