Yamato CF-303Y Water Circulator/Chiller -20°C to 30°C 3.9L 115V
Contact us to confirm current lead times and real-time availability for this model.
The Yamato CF-303Y is a compact, high-performance laboratory water circulator/chiller designed for precise temperature control in research and analytical lab environments. With a 3.9L stainless steel bath and a cooling range of -20°C to 30°C (cooling only — no heating function), the CF-303Y delivers stable, reliable fluid temperature control for rotary evaporators, analytical instruments, jacketed reactors, and other lab equipment requiring consistent process cooling.
The CF-303Y is a popular rotary evaporator chiller and laboratory recirculating chiller for pharmaceutical, chemical, and university research labs. Its closed-loop circulation system, R452A refrigerant, and space-saving footprint make it an ideal benchtop lab chiller for facilities requiring dependable sub-ambient cooling without a large equipment footprint. The plug-and-play 115V operation requires no special wiring, making it easy to deploy in any standard lab environment.
Key Features:
- Cooling range: -20°C to 30°C (cooling only — no heating function)
- 3.9L stainless steel bath (3.5L usable liquid volume)
- Cooling capacity: ~450W at 10°C / ~330W at -10°C
- Temperature control accuracy: ±1.0°C (≥20°C) / ±1.5°C (<0°C)
- Max flow rate: ~10 L/min | Max head: ~5.7m
- R452A refrigerant | Stainless steel cooling coil
- User-friendly controller: White LED digital display, key entry, 1°C minimum digit
- Auto resume function and calibration offset
- 115V / single phase — standard outlet, no special wiring required
