Controlled Temperature Cycling in a Research Lab

Direct contact cooling 65°C below ambient:

controlled temperature cycling A large state university in the U.S. has been using a collection of several TECA Model AHP-1200CAS Cascaded Cold/Hot Plates for years, to perform various research on the characteristics of cement paste samples.

In a cascaded system, the thermoelectric element acts as a heat sink for the element above it. Therefore, the more “stages” there are, the colder the top-most stage becomes. The research team which provided this photo successfully ran temperature profiles such as: from -20° to +24°C, and +23° down to -40°. This consistent accuracy and reliability of TECA Cold/Hot Plate products are a smart addition to any lab needing plug-and-play benchtop cooling or heating.

All Laboratory-Style TECA Cold/Hot Plates include an integral temperature controller and tecaLOG communications software. Versatile accessories are available such as cutting surfaces for grossing, barriers for lab animals, and more. The possibilities are endless.

Where Are All the Cold Plates?

Cooling micro-organisms in a lab:

Recently, a prestigious U.S. university’s research lab contacted TECA. The team needed to cool a 340-well micro plate. Their vendors had many hot plates to offer, but no one seemed to offer a like product for cooling. The lab team was happy to discover TECA products online and the AHP-301CPV proved to be the right fit.

The lab’s 340-well plate is filled with a solution housing micro-organisms. To get the organisms to migrate to the bottom of the wells, the lab needed controlled cooling to 0degC. However, there is a limited temperature range in which the organisms do not degrade so precise control was paramount.

Freeze Tape Casting

May 10, 2018 by Afshin

Freeze Tape Casting Manufacturer:

A materials science company specializes in creating foams with specific porosity for use in electric vehicles, batteries, thermal interface materials and ceramic-metal interfaces. Utilizing a TECA thermoelectric cold plate as a component within the freeze tape caster ensures the manufacturing process remains environmentally friendly. Peltier cold plates use no freon, coolants, or chemicals of any kind. In this example, the customer has slightly modified a commercially-available, off-the-shelf (COTS) TECA cold plate to reach the desired -10C set point.

Liquid Cooled Cold Plate

Newest Liquid Cooled Cold/Hot Plate LHP-1800CPV:

Liquid Cooled cold/hot plates have the freedom from the noise and vibration of fans. Water works as the coolant, carrying heat away from the cold plate source. TECA’s newest liquid-cooled cold/hot plate is also its largest. The LHP-1800CPV features a 15.2” X 19.2” footprint and a range from -30C to +130C (high temperature version). A water source is required. The LHP-1800CPV is ideal when powerful cooling is needed in a small footprint.

TEMPERATURE GRADIENT

August 12, 2016August 5, 2016 by Afshin

Agricultural Research Using Temperature Gradient:

A department of the Canadian government uses two TECA Thermal Gradient Bar (TGB-5030) systems to conduct thermal behavior research on insects.

In the photographs shown here, the customer used two AHP-1200CPV Cold/Hot plates plus one Large Gradient Plate (p/n TGB-5030) and created a gradient area spanning from 4 °C to 33 °C. Two groups of insects were placed side-by-side on the gradient bar, in separate cages. This allowed the researchers to test two groups at the same time.

The gradient plate shown is not TECA’s. It’s from a University. They had been running a hot plate on one end and a liquid cooled LHP-300CP with the plate in the evaluation of temperature preference in insects.

They needed better control and a wider temperature range and they wanted it on their existing plate. Many tests were run with the AHP-301CPV (shown) and the AHP-1200CPV to evaluate temperature uniformity and differential.

More and more researchers are looking into the versatile CPV line of cold plates to improve their tests with the CPV line of products and accessories. Call us. Maybe we can help you too.

FIBER OPTICS

The customer makes fiber optics and related components and subsystems, they use an AHP-1200CPV cold plate for testing components.

They are using it to run temperature test on them, they set the temperature, and it goes to temperature and sits there, heating or cooling.

“It works well”. Before they were cobbling together home brew solutions with a heater here, a circuit and a fan there but it’s nice to have a system that does it all.

A private biopharmaceutical company formulates drugs that are sensitive to temperature. TECA Model AHP-1200 CPV is their perfect benchtop cooling solution. The customer uses the AHP-1200 CPV Cold Plate in combination with the customer’s own aluminum blocks to keep solutions at 0C during filtration and vial filling operations.

The customer reports, “We have been very satisfied”. This customer provided photo is a wonderful example of the versatility of TECA’s line of Laboratory Cold/Hot Plates. The plate surfaces are appropriately sized to accept microtiter plates and other lab accessories. The temperature can be read from either the plate surface or anywhere a remote sensor can be placed, via the Remote Sensibility™ feature.
