The Grant LTC4R provides outstanding performance for routine and sophisticated applications requiring accurate temperature control in the range of -30 to 100°C. The LTC4R includes the TX150 heating circulator and an R4R tank/refrigeration unit, complete with insulated tubing and clips to form a system ready to use.

The TX150 Optima™ is high-performance programmable digital heating circulator with an exceptionally simple user interface. This allows fast set-up of multiple parameters through a powerful menu system and provides sophisticated control for temperature-controlled applications.

USB connectivity is available to a PC or laptop. It is programmable with Labwise™ PC software, a software program to set all parameters, including programs, via the PC. Labwise™ also features real-time status windows, a graphic display of the controller's performance as a program is run, and allows data to be logged for future recall and analysis.

  • Powerful pump for external circulation, maximum flow 18 L/min, maximum pressure 310 mbar
  • Full colour QVGA TFT display
  • Setpoint, plus three adjustable preset temperature values
  • Timer function for reaction timing, 99 hours, 59 minutes, with audible alert and heater control
  • Liquid selection safety feature adjusts for temperature range or heater power
  • Fault indication display
  • Programmable relay
  • Two-point user recalibration of internal and external probes (PEP, SEP)
  • Off-set adjustment for optimal isothermal performance
  • Can be programmed to switch the refrigeration on and off during a heating and cooling program
  • Memory capacity for one program of up to 30 segments
  • Choice of languages: English, French, German, Spanish and Italian
  • Low liquid protection by float switch
  • Adjustable over-temperature cut-out
  • Convenient accessory clamp available for fitting to vessels
  • Stability ± 0.1°C

Note: The refrigeration unit can be switched off independently of the circulator to allow heating only applications. All the refrigeration base units can be used up to a maximum temperature of 100°C.

‍

Input to enable switching of the cooling system by an external device (typically a Grant Advance Optima).
