Refrigerated Incubator Programmable With Window 286L Overview
The Refrigerated Incubator Programmable With Window 286L (model IN804W) is a forced-air convection refrigerated incubator from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. This 286 L chamber maintains setpoints across a −10 to +50°C operating range, supporting low-temperature work and environmental testing.
Stainless steel lines the interior, while a chrome-free electrogalvanized steel exterior carries a chemical-proof baked finish. A triplex glass door — dual outer glazing plus an inner door — improves heat retention and lets technicians observe samples through a W516 × H416 mm window with key. Styrene foam insulation surrounds the chamber.
Buyers select 115V or 220V to match site power. The unit measures 39 × 39 × 78 in and weighs 475 lbs, requiring floor placement with adequate clearance. Manufactured in Japan, it is backed by ISO 9001:2015 and ISO 14001:2015 documentation.
Key Features
- PID temperature control: ±0.3°C accuracy in continuous operation, with programmable setpoints.
- Temperature distribution: ±1.0°C uniformity at 37°C in continuous operation.
- Triplex glass door: dual outer glazing plus inner door for heat retention, with a W516 × H416 mm observation window and key.
- Refrigeration and heating: air-cooled hermetic 300 W compressor (R404A) paired with a 750 W iron-chrome wire heater.
- Defrost management: manual ON / auto OFF defrost with timer and cycle operation.
- Dual sensing: Pt100Ω controller sensor plus K-thermocouple overheat prevention.
How to Choose the Right Incubator
Refrigerated incubators differ by chamber size, achievable temperature range, and control sophistication. Match these axes to your protocol .
- Capacity: a 286 L chamber suits multi-shelf sample loads; confirm your throughput fits the usable interior.
- Temperature range: the −10 to +50°C span enables sub-ambient work that heat-only units cannot reach.
- Control type: PID control with programmable steps supports ramped or cyclic profiles rather than single fixed setpoints.
- Voltage: select 115V or 220V to match available site power and avoid transformer add-ons.
- Footprint: verify floor space for the 39 × 39 × 78 in cabinet and its 475 lb load rating.
- Safety: independent K-thermocouple overheat protection guards samples against runaway conditions.

Frequently Asked Questions
What is the operating temperature range of the IN804W?
The IN804W operates from −10 to +50°C. This sub-ambient capability supports low-temperature tests and environmental conditioning that heat-only incubators cannot perform.
How large is the chamber and the overall unit?
The chamber holds 286 L. The complete cabinet measures 39 × 39 × 78 in and weighs 475 lbs, so plan for floor placement with service clearance.
What voltage options are available?
Two voltage configurations are offered: 115V (IN-804W-115V) and 220V (IN-804W-220V). Select the one matching your site power; both share identical specifications otherwise.
How accurate and uniform is the temperature control?
Temperature control holds ±0.3°C accuracy in continuous operation. Distribution uniformity is ±1.0°C at 37°C, managed by PID control with a Pt100Ω sensor.
What materials are used in the interior and exterior?
The interior is stainless steel. The exterior uses chrome-free electrogalvanized steel plate with a chemical-proof baked finish, and styrene foam provides insulation.
Does the unit allow sample viewing without opening the door?
Yes. A triplex glass door with a W516 × H416 mm observation window and key lets technicians inspect samples while preserving chamber temperature.
