Refrigerated Incubator Programmable 286L Overview
The Refrigerated Incubator Programmable 286L (IN804) from Yamato Scientific is a forced-convection incubator built for low-temperature and environmental testing, with a 286 L chamber and an operating range of -10 to +50°C. LabSupplies.com supplies this unit as an authorized dealer.
A stainless steel interior resists corrosion across repeated low-temperature cycles, while the exterior uses chrome-free electrogalvanized steel with a chemical-proof baked finish. Styrene foam insulation supports temperature stability. PID control with a Pt100Ω sensor holds ±0.3°C accuracy, and an inner glass door lets technicians observe samples without disturbing chamber conditions.
Available in 115V and 220V configurations, the IN804 measures 36 × 34 × 73 inches and weighs 442 lbs. Refrigeration comes from a 300 W air-cooled hermetic compressor (R404A). Manufactured in Japan, the unit ships with ISO 9001:2015 and ISO 14001:2015 documentation.
Key Features
- Programmable PID control: precise setpoint management across the full -10 to +50°C range.
- High-accuracy temperature: ±0.3°C control accuracy and ±1.0°C distribution at 37°C during continuous operation.
- Inner glass door: keeps chamber temperature stable while technicians observe samples.
- Forced air convection: uniform heat distribution backed by a 750 W iron-chrome wire heater.
- Dual sensing: Pt100Ω controller sensor plus a K-thermocouple for overheat prevention.
- Flexible defrost: manual ON / auto OFF defrost with timer and cycle operation.
How to Choose the Right Incubator
Selecting a refrigerated incubator means matching chamber capacity, temperature range, and site power to your testing protocol. Use these axes to confirm the IN804 fits your workflow before ordering.
- Capacity: the 286 L chamber suits batch sample loads and larger vessels; confirm your throughput against available shelf volume.
- Temperature range: the -10 to +50°C span covers low-temperature and environmental tests below ambient, which non-refrigerated incubators cannot reach.
- Control type: programmable PID control supports multi-step profiles, an advantage over fixed-setpoint analog units.
- Voltage: choose 115V or 220V to match your laboratory circuit and regional power supply.
- Footprint: verify the 36 × 34 × 73 inch dimensions and 442 lb weight against bench or floor clearance and load limits.
- Safety: the independent K-thermocouple overheat prevention guards samples against runaway heating.

Frequently Asked Questions
What is the operating temperature range of the IN804 incubator?
The IN804 operates from -10 to +50°C. This refrigerated range supports low-temperature and environmental testing below ambient, with ±0.3°C control accuracy during continuous operation.
What is the chamber capacity and how large is the unit?
The chamber holds 286 L. The full unit measures 36 × 34 × 73 inches (L × W × H) and weighs 442 lbs, so verify floor clearance and load limits before installation.
Is the IN804 available in both 115V and 220V?
Yes. The IN804 ships in 115V (IN-804-115V) and 220V (IN-804-220V) configurations. Select the voltage that matches your laboratory circuit and regional power supply.
What materials are used in the chamber and exterior?
The interior is stainless steel for corrosion resistance. The exterior is chrome-free electrogalvanized steel with a chemical-proof baked finish, and styrene foam provides heat insulation.
How does the IN804 control and protect temperature?
The IN804 uses programmable PID control with a Pt100Ω sensor for ±0.3°C accuracy. A separate K-thermocouple provides independent overheat prevention to protect samples.
What is the difference between the two IN804 models?
The two IN804 models differ only by voltage. Both share the 286 L capacity, -10 to +50°C range, and PID control; one runs on 115V and the other on 220V.
