Why use a Cold Plate Air Cooled Heater/Cooler?

Cold Plates using Peltier cooling technology are useful whenever your liquid handling lab needs cooling or heating surfaces. They offer heating and cooling plus temperature control all in one instrument. That makes them particularly suitable when you’re working with cell assays and biological and chemical samples in an automated workflow.

What to look for in a Cold Plate Air Cooled Heater/Cooler?
Accurate and uniform heating and cooling are important, as are the ability to maintain temperature precisely. You may also need to consider temperature ramp rates and the maximum achievable temperature.

Temperature uniformity - delivering identical temperature across the entire block, with identical results for samples in the middle or on the edge of the block, and throughout the run.
Temperature accuracy - ensuring accurate and stable, reproduceable temperatures for the duration of the run, and for every sample in the block.
Uniform temperature change (ramp rates) - maintaining temperature uniformity across the entire block.
Temperature range - maximum and minimum temperature offered.
Small footprint - delivering the required performance while taking up as little space in the workflow as possible.
Low profile - to make pipetting and use of taller disposables easier.

Use of the Inheco CPAC

The CPAC is in regular use in NGS Sample Prep and is used for incubation by molecular biologists.

The CPAC Microplate is especially useful for enclosed liquid handling platforms (or workstations), when the workflow or samples can overheat if too many instruments without liquid cooling are integrated and waste heat is not efficiently removed. The CPAC microplate can be integrated into the workflow with waste air routed below the workflow.

The CPAC is often used to protect samples from degradation due to changes in heat, and to keep reagents, probes and end products at the correct temperature.

Precise, uniform heating, cooling and temperature control from Inheco CPAC

Heating and cooling
All CPAC models heat and cool using one or two Peltier units.

Peltier Modules or Thermoelectric Coolers (TECs) use the Peltier effect to create a heat flux between the junction of two different types of materials. A Peltier module is a solid-state active heat pump which transfers heat from one side of the device to the other side against the temperature gradient (from cold to hot), with consumption of electrical energy. TECs run with DC voltage, and it’s easy to control the heat transfer through the module by changing the current. When the polarity of the DC is switched, the TEC swaps from cooling to heating mode. That makes TECs an excellent solution when exact control of temperature and heating and cooling rates are needed.
Temperature range: +4 °C to +70 °C (TEC versions) or +4°C to +110°C (HT 2-TEC versions).
HT 2-TEC versions:
Heating from 25 °C to 85 °C in 600 sec: 6 °C/min
Cooling from 90 °C to 25 °C in 700 sec: 5.2 °C/min

Optional Heated Lid

The Heated Lid can be used as an add-on heater on top of the CPAC, to increase the rate of heating, improve temperature uniformity (especially for deep well plates), and enable longer incubation.
The Heated Lid helps to avoid condensation at the top of the plate, and reduce losses due to evaporation, without needing the space of a dedicated incubator.
The flexible cable and low weight (420 g) mean it can be transported by most gripper systems, while being heavy enough to seal the plate, so allowing full automated processing.
