This listing is for the Grant GD120 Water Bath/Circulator

The unit is in full working condition and is ready for immediate use

The Grant GD120 is a digitally controlled stirred water bath and circulator ideal for laboratory use, offering high precision and flexibility. Here's a breakdown of its features and capabilities:

Key Features

Immersion Thermostat with Intelligent Control Optimisation (ICO): Enables adaptive PID control for exceptionally stable temperature regulation.

Integral Pump: Built-in circulation pump with a maximum flow rate of 17 L/min, allowing both sample immersion and external fluid circulation.

User Interface: Equipped with a clear digital display, a rotor plus two-key control, timer function for reaction timing, and visual + audible alarms to notify operators of critical conditions.

Preset Temperature Control: Supports one adjustable operating setpoint plus three preset temperature options for fast switching.

Safety Features: Includes float-switch low liquid protection and an adjustable over-temperature cut-out for sample and user safety.

Liquid Type Selection: Automatically adjusts heater power and temperature parameters depending on chosen liquid (e.g., water, oil, glycol mixtures).

Temperature Range & Accuracy

Plastic Tanks (P-series): From around ambient +5 °C up to ~99 °C.

Stainless Steel Tanks (S-series): From –15 °C up to ~120 °C.

High Stability: ±0.02 °C for stable temperature control.

Technical Specifications & Obsolescence

The GD120 series includes multiple tank sizes: plastic tanks (P5, P12, P18) and stainless steel tanks (S5, S12, S18, S26, S38), offering varied capacities for different lab needs.

This series is now considered obsolete, though it remains functional and reliable for many applications.

Supporting Documentation & Manual

Operating Manual: The GD120 is covered by the general purpose stirred thermostatic baths manual (shared with GD100), outlining temperature settings, calibration procedures, safety guidance, and maintenance.

Datasheet Summary: Positioned within the broader Grant Optima product range, the GD120 sits between simpler (GD100, up to 100 °C) and higher-spec models (GR150 up to 150 °C, GP200 up to 200 °C)
