The Waters Temperature Control Module II (TCM II) is a laboratory temperature-control unit designed for use with Waters chromatography systems and compatible Column Heater Modules (CHM). The photographed instrument is clearly identified on the front panel as a Waters Temperature Control Module and features a digital temperature display, front-panel keypad, unit selection controls, remote-control function, upper/lower temperature limit controls, and dedicated temperature monitoring functions.

The Waters TCM II is designed to provide centralized temperature control for compatible column heater modules used in liquid chromatography applications. Waters documentation confirms that the TCM II can independently control up to three Column Heater Modules, while the complete Waters Temperature Control System kit WAT038039 consists of a TCM II and one Column Heater Module (WAT038040).

The photographed unit shows visible cosmetic wear, dust, scratches, discoloration, and signs of previous laboratory use. The front display and keypad are present, but the operational condition, display accuracy, communication interfaces, temperature-control performance, and compatibility with a specific CHM or HPLC system should be verified before purchase.

Applications

The Waters Temperature Control Module II is primarily used in HPLC and chromatography laboratories where stable and controlled column temperatures are required. It can be paired with Waters Column Heater Modules to regulate the temperature of chromatography columns and associated components during analytical separations.

The TCM II can independently control one, two, or three compatible Column Heater Modules, with the temperature of each module monitored through the control system. Waters documentation also indicates that the Temperature Control System can be controlled through compatible Waters chromatography software such as Empower or Millennium.

Technical Specifications

*The 0–150 °C range applies to the compatible Waters Column Heater Module when controlled by the TCM II; Waters notes that the TCM II cannot be programmed below room temperature and the set point should be at least 5 °C above ambient.

Waters identifies the complete Temperature Control System as WAT038039, consisting of a Temperature Control Module II and one Column Heater Module, while the CHM itself is WAT038040.

Benefits of Refurbished Laboratory Equipment

Purchasing a refurbished Waters Temperature Control Module II can provide laboratories with a cost-effective way to maintain or expand existing Waters chromatography systems. Temperature control can be important in HPLC because column temperature can influence retention, selectivity, viscosity, and overall chromatographic reproducibility.

A refurbished TCM II may be particularly useful for laboratories maintaining legacy Waters HPLC equipment, educational institutions, analytical laboratories, and research facilities that already have compatible Column Heater Modules. Proper inspection and testing can help determine whether the controller is suitable for the intended chromatography configuration.

Additional Information

The photographed unit is offered as a Waters Temperature Control Module II. The image shows only the controller and does not confirm the presence of a Waters Column Heater Module, power cable, communication cable, temperature-control accessories, or other components. The listing should therefore be considered for the TCM II controller only unless additional accessories are specifically included in the sale.

The unit has noticeable cosmetic wear, dust, scratches, discoloration, and surface marks. Exact electrical specifications, serial number, rear-panel connections, software compatibility, communication interface, and operational temperature-control performance should be verified before purchase. Compatibility with the buyer's specific Waters HPLC/CHM configuration should also be confirmed.
