Grant Instruments TXF200-R4R Optima TXF200 Heated Circulating Bath with Refrigerated Unit
 |
 |
The Grant TXF200 series of digital heating circulating baths for sophisticated applications require complex programming and/or ultra-precise temperature control in the range of -15°C to 200°C. The TXF200 heating circulator can be used in combination with any Grant stainless steel or plastic tank or with a T-CLAMP for independent use of virtually any vertical-sided tank.
- Cooling/heating range -15°C to 200°C
- Stability ±0.01ºC / Uniformity ±0.05ºC
- Tank options 5L to 38L
- Powerful integral pump for external fluid circulation
- Large, bright full color display with a choice of 5 languages
- 5-point user calibration
- Low-liquid detection (float switch)
- Memory capacity for 10 programs with 100 segments
Applications
- Industrial labs – thermostat calibration, haze analysis (brewing), temperature probe calibration, and material testing
- University research – temperature control of external equipment such as spectrophotometers and refractometers
- Circulation of temperature control fluid to jacketed vessels

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 (R290)
- 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.
