Refrigerated Circulating Baths

The Grant Optima™ TX150 series of digitally controlled refrigerated circulating baths provides outstanding performance for routine and sophisticated applications requiring accurate temperature control in the range of -47 to 100°C.

Grant TX150 series refrigerated systems combine the powerful and versatile Grant Optima™ digital heating circulator TX150 with a  rugged stainless steel refrigeration unit with different facilities and working volumes.

The Grant Optima™ TX150is 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.

The TX150 has USB connectivity to a PC or laptop. It is programmable with Labwise™, 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.
