Grant Optima™ TC120 Immersion Circulator

The Grant Optima™ TC120 immersion circulator is a versatile and reliable solution for precise temperature control in laboratory environments. With a temperature stability of ±0.05 °C and uniformity of ±0.1 °C, it operates across a wide range from −15 °C to +120 °C (when used with an external cooler). The built-in circulation pump, combined with intelligent PID control (ICO – Intelligent Control Optimisation), ensures even heat distribution for both internal baths and external applications.

The TC120 is compatible with a wide variety of tanks (5 to 38 liters), including plastic or stainless-steel containers, and can be securely mounted using the included T‑clamp. Its user interface features a rotary dial, two functional buttons, and a clear 4-digit LED display, offering intuitive control without complexity. The system includes over-temperature protection, timer functionality, and three programmable temperature presets—making it ideal for repeatable procedures.

With no complicated configuration required and support for optional external coolers, the Grant Optima™ TC120 is suitable for a range of applications in biology, chemistry, pharmaceuticals, food industry, and metrology. Whether used for heating test tubes, reaction flasks, or as part of a circulating setup in process systems, it offers exceptional performance in a compact design. Manufactured in the UK, this circulator represents the gold standard in its category for precision, reliability, and ease of use.
