Thermal Cycling with TEC Controllers

TEC controllers are used for thermoelectric cooling and heating in combination with Peltier elements or resistive heaters. Peltier elements are heat pumps which transfer heat from one side to the other, depending on the direction of the electrical current. This allows switching between heating and cooling without any mechanical changes. No compressor is needed.

TEC Controller Product Overview

Applications

A typical PCR profile

A typical PCR profile

Cooling and heating for applications with small thermal load and high precision requirements is ideally done using thermoelectric cooling (Peltier elements).

Typical Applications:
  • PCR (Polymerase Chain Reaction)
  • Thermal cycling of biomedical samples
  • Hardening / setting of adhesives
  • Sensor cooling
  • Applications where compressor cooling is not suitable

Implementation with TEC Controllers

Flexible and convenient ways to create temperature profiles:

  • Programmable temperature profiles using lookup tables (autonomous mode)
  • Remote control of temperature
  • Adjustable slopes of up- and down ramps
  • Precise and fast temperature control
  • Temperature logging
  • Large temperature range (-50 to 200 °C)

Features and advantages of our TEC Controllers

Operation Modes

TEC Controllers in combination with Peltier elements allow the creation of temperature profile cycles with predefined curves, ramps, slopes and hold times.

Autonomous mode: Temperature profiles and number of cycles can be programmed into the memory of the TEC Controller using lookup tables. These lookup tables can be defined in Microsoft Excel, exported and loaded as CSV file. (See user manual chapter 4) External triggering is possible.

Remote control: Temperature set-points can be externally generated, sent to the TEC Controller, and triggered in a live mode.

Logged temperature and operation parameter data can be exported for documentation, reproducibility and further analysis.
