R4R Series Refrigerated Circulating Bath
The Grant R4R refrigerated bath and circulator range provides outstanding performance for routine and sophisticated applications requiring accurate temperature control in the range of -30 to 100°C.
A choice of 4 heating circulators combined with a powerful R4R refrigeration unit offers a cost-effective and efficient solution for low temperature applications.
Additionally, Grant also offers the LTC4R kit, which is available as a ready assembled system including TX150 heating circulator mounted on the R4R refrigeration unit and comes supplied with insulated tubing and clips.
The Grant R4R range, which can be combined with any of our T100, TC120, TX150 or TXF200 heating circulators, offer a number of features:
- Stability of up to ±0.1°C
- Up to 3 years warranty
- No spill valved front drain
- 3 preset programs
- Large 20 litre tank and accessible bath for immersion of samples
- Environmentally friendly refrigerant
- Robust construction
- 900W of cooling power
- Quiet
- Built in Britain
- Range of accessory hosing, connectors, software, additional pump and temperature probes available
Note: The refrigeration unit can be switched off independently of the heating circulator to allow heating only applications. All the refrigeration base units can be used up to a maximum temperature of 100°C.
Applications
- University research/teaching - temperature control of external equipment including: spectrophotometers & refractometers. Circulation of temperature control fluid to jacketed vessels, cooling crystallisation vessels
- Industrial laboratories - temperature probe calibration, product testing, product QC, temperature control of external equipment.
