The Grant Instruments Optima GD120 series of digitally controlled stirred water baths and circulators provides outstanding performance and value for money for more sophisticated applications requiring accurate temperature control up to a maximum of 120 degC.

Grant Instruments GD120 series systems combine the versatile Grant Instruments Optima GD120 digital immersion thermostat with a choice of three economy plastic (P) tanks or five stainless steel (S) tanks with different capacities.

The Grant Instruments GD120 immersion thermostat incorporates Intelligent Control Optimisation (ICO) for adaptive intelligent PID temperature control and includes a powerful integral pump, making GD120 systems suitable both for immersing samples and circulating temperature controlled fluid to external devices. It includes a convenient timer function for reaction timing and a variable high temperature alarm setting. The temperature range and heater power are automatically limited according to the liquid type selected.
