Block heaters with cooling function for flexible laboratory applications
Block heaters that can both cool and heat significantly expand the range of applications compared to heating-only devices. The integrated cooling function allows samples to be tempered below room temperature, which may be required for enzymatic reactions, the storage of temperature-sensitive reagents, or specific incubation protocols.
Design and functionality
These block heaters use Peltier elements or compressor cooling to reach temperatures below ambient. The metal block accommodates interchangeable inserts adapted to different vessel sizes. Electronic control with an LCD display enables precise temperature settings and programmed sequences.
Devices with interchangeable blocks
The KühlHeizBlockThermostat TK 23 offers space for two interchangeable blocks and features programmable control. This allows different vessel formats to be tempered in parallel or various temperature profiles to be processed sequentially. The cooled thermomixer AccuTherm combines temperature control with a mixing function and is supplied as a base unit without a block.
Selection criteria for cooling block heaters
When selecting a block heater with a cooling function, the required temperature range, the number and size of samples, and the desired program functions are decisive. Devices with programmable control enable automated temperature ramps and hold times for reproducible results.
Typical areas of application
Cooling block heaters are used in molecular biological research, PCR preparation, enzyme kinetics, and pharmaceutical quality control. These devices are indispensable wherever samples must be kept at a defined temperature below room temperature or cycled between different temperature levels.
Frequently asked questions about block heaters with cooling function
Here you will find answers to important questions regarding cooling block heaters.
What are block heaters with cooling function used for?
These devices are used for the precise temperature control of samples in reaction vessels, tubes, or microtiter plates. They enable both heating and cooling below room temperature, which is necessary for enzymatic reactions, incubations, and the storage of temperature-sensitive substances.
Which block size is suitable for my laboratory?
The choice depends on the number and size of the samples to be tempered. Devices like the TK 23 with two interchangeable blocks offer flexibility for different vessel formats. For changing requirements, systems with interchangeable inserts are recommended.
Which cooling methods do these block heaters use?
Most compact block heaters with a cooling function operate with Peltier elements, which are low-maintenance and quiet. For lower temperatures or higher cooling capacities, compressor systems are also used.
What distinguishes cooling block heaters from heating-only models?
Heating-only block heaters can only reach temperatures above ambient. Devices with a cooling function also temper below room temperature and enable active cooling, which is necessary for rapid temperature changes and defined cooling protocols.
What accessories are useful for block heaters?
Interchangeable blocks for different vessel sizes expand the application possibilities. Additionally, external temperature sensors, heated lids to prevent condensation, and documentation software for GLP-compliant logging can be useful.
How do I receive a quote for a cooling block heater?
You can submit a quote request via the product pages. If you have questions about device selection or specific requirements, our specialist consultation team is available to help you determine the right device for your application.
How is temperature calibration performed for block heaters?
Calibration is generally performed using calibrated reference thermometers inserted into the block. Many devices offer a software-based calibration function. For regulated areas, regular calibration by accredited service providers is recommended.
