Warner Instruments TC-324B Automated Temperature Controller

The TC-344B temperature/heater controller provides quiet electrical power to a variety of Warner's perfusion heating devices including Series 20 Heated Platforms, the RC-30HV confocal imaging chamber, solution in-line heaters (e.g. SH-27B, SF-28, etc.) and the DH-35i Series culture dish heaters. It also supply heating power to SW-61 and SW-10/6 syringe warmers, as well as the QE-1 Platform for Series 40 recording chambers and the DH-35i culture dish incubation system. This instrument can also be easily adapted for use with custom built equipment according to the requirements of the user.

Each channel can supply up to 18 watts into a load of 8 ohms. Maintenance of heat setpoint is controlled automatically in Auto mode via thermistor feedback. A loop-speed selector allows for selection of three feedback speeds to optimize stability for thermal response characteristics of the device being heated. Heat setpoint maintenance may also be manually controlled in Manual mode.

Ease of Use

In Auto mode, the desired temperature is set with a single set temperature control. The connected chamber platform, solution heater or other device is automatically controlled to the set temperature. Accuracy is typically better than ± 1°C, and under ideal conditions will approach ± 0.1°C. In Manual mode, the controller provides a variable DC output adjustable from zero to +12 volts.

Quiet Operation in Recording Setups

Highly filtered DC supplies and slow-ramped analog switching circuitry deliver power without adding noise to the system.

Thermistor Readouts

Each channel reads two thermistors simultaneously: T1 for the control of the system, and a T2 for any point of interest. These temperatures are read on the meter and also available at front panel outputs for recording devices. Unical thermistors are used and can be replaced without the need for recalibration.

Description:

The Warner Instruments TC-324B Automated Temperature Controller is a versatile, user-friendly thermal control system designed to provide precise and reliable temperature regulation for a wide range of laboratory applications. This unit excels in both automatic and manual modes, offering complete control over heating power, which can be tailored to suit various experimental needs. Although optimized for use with Warner Series 20 chambers and in-line solution heaters, the TC-324B can easily be adapted for use with custom-built equipment, making it highly flexible and adaptable.

In automatic mode, the TC-324B takes full control over the heating power, maintaining the set temperature with minimal intervention. In manual mode, the user has the option to adjust settings for more direct control. The system’s dual thermistor design ensures accurate temperature monitoring at both the system and a separate point of interest, and the built-in loop-speed selector optimizes response based on the thermal delay characteristics of the environment.

The TC-324B is ideal for laboratory setups in live cell imaging, electrophysiology, microscopy, and other applications where precise temperature control is essential.
