Refrigerated Incubator Programmable 143L Overview
The Refrigerated Incubator Programmable 143L (model IN604) from Yamato Scientific is a forced-convection refrigerated incubator built around a 143 L chamber and an operating range of -10 to +50°C. LabSupplies.com, an authorized dealer, supplies this unit for low-temperature work and environmental testing that demands stable, programmable conditions.
Construction centers on a stainless steel interior chamber, paired with a chrome-free electrogalvanized steel exterior finished in a chemical-proof baked coating. Styrene foam insulation and an inner glass door hold temperature steady during sample observation. PID control draws on a Pt100Ω sensor, while a K-thermocouple handles overheat prevention.
Two voltage builds are offered — 115V and 220V — to match laboratory circuits. Refrigeration relies on a 250 W air-cooled hermetic compressor (R134a), backed by a 550 W iron-chrome wire heater. Manufactured in Japan under ISO 9001:2015 and ISO 14001:2015, the unit measures 36 × 36 × 46 inches and weighs about 300 lbs.
Key Features
- Programmable operation: set multi-step temperature profiles for low-temperature and environmental testing.
- Wide refrigerated range: forced-air convection from -10 to +50°C for cooling and incubation tasks.
- High-accuracy control: PID control delivers ±0.3°C accuracy in continuous operation and ±1.0°C distribution at 37°C.
- Inner glass door: view samples while keeping chamber temperature stable.
- Dual sensing: Pt100Ω controller sensor with an independent K-thermocouple for overheat protection.
- Managed defrost: manual ON, automatic OFF, and timer-based cycle operation keep the chamber frost-free.
How to Choose the Right Incubator
Refrigerated incubators differ in chamber size, temperature span, control sophistication, and site requirements. Match these axes to your protocol and laboratory infrastructure before specifying a unit.
- Capacity: the 143 L chamber suits mid-volume sample loads; confirm your throughput and shelf needs fit the interior.
- Temperature range: a -10 to +50°C span covers sub-ambient incubation and environmental testing that a heat-only unit cannot reach.
- Control type: programmable PID control supports multi-step profiles and tight accuracy, important for reproducible, validated runs.
- Voltage: choose 115V or 220V to match the dedicated circuit serving your bench or equipment room.
- Footprint and weight: at 36 × 36 × 46 inches and roughly 300 lbs, verify floor space, clearance, and access routes.
- Safety: an independent overheat thermocouple protects samples and equipment during unattended operation.

Frequently Asked Questions
What is the temperature range of the Yamato IN604 incubator?
The IN604 operates from -10 to +50°C using forced-air refrigerated convection. PID control holds accuracy to ±0.3°C in continuous operation, with temperature distribution within ±1.0°C at 37°C.
What is the chamber capacity and overall footprint?
Chamber capacity is 143 L. External dimensions measure 36 × 36 × 46 inches (L×W×H) and the unit weighs about 300 lbs, so plan floor space, clearance, and delivery access accordingly.
What voltage options are available?
Two configurations ship: 115V (SKU IN-604-115V) and 220V (SKU IN-604-220V). Pick the version that matches your laboratory circuit; refrigeration uses a 250 W air-cooled compressor and the heater draws 550 W.
What materials are used in construction?
The interior chamber is stainless steel, while the exterior is chrome-free electrogalvanized steel with a chemical-proof baked finish. Styrene foam insulation surrounds the chamber, and an inner glass door allows sample observation without disturbing conditions.
How does the defrost system work?
Defrost runs with manual ON and automatic OFF, governed by a timer for cycle operation. This arrangement keeps the refrigerated chamber clear of frost during extended low-temperature runs.
Is the IN604 certified to recognized quality standards?
Yes. Yamato Scientific manufactures the IN604 under ISO 9001:2015 and ISO 14001:2015 management systems. Production takes place in Japan.
