CONDENSING VAPOR

Condensing Vapor: AHP-470CP in Laboratory Reactor Instrumentation

condensing vapor   cooling vapor stream

In a chemical process (catalysis), the customer uses several TECA Model AHP-470CP Cold Plates to condense methanol out of a vapor stream and collect liquid in the 100 mL glass vessels shown. The AHP-470CP offers a convenient small size and is customizable to the end user’s needs.

Please see the “Options” section on the product data sheet to learn more.

Three AHP-1200CPV Cold Plates are running continuously and in tandem at 17 °C to monitor satellite equipment. The customer has added air deflectors of his own design. TECA offers standard air deflectors as well. The customer applies approximately 50 watts of heat to the cold plate.

Pain Research

Using TECA’s Dual Cold/Hot Plate, a health psychology lab in a large university is conducting a study on the relationship between pain sensitivity and inflammation in human subjects.

The human subject places his or her hand on the surface of TECA’s AHP-1200DCP Dual Cold/Hot Plate for a period of time. Researchers are using set points between 52 °C and -4 °C and can utilize the included communications software to program ramp and soak profiles.

TEMPERATURE PREFERENCE TEST

Temperature Preference Test:

TECA’s model AHP-1200DCP consists of two adjacent thermoelectric heat/cool plates (dual zone cold plate).

In this example, the customer has added an optional Plexiglas barrier that allows the rat to easily move between the two surfaces. One plate was set at 30 ºC and the other plate was alternately set also to 30 ºC or to a different temperature. Animals spent time on each plate.

The customer studies whether rats/mice exhibit a significant, temperature-dependent avoidance of plates after injection of analgesic drugs.

ANIMAL BEHAVIOR RESEARCH

Animal Behavior Research:

Investigating the changes in behavioral responses due to changes in experimental floor temperature and dermal application of heating/cooling compounds in an animal model requires precise temperature control system.

The TECA AHP-1200DCP dual zone cold/hot thermoelectric plate with two independently controllable temperature zones provides precise regulation of the floor temperature and change of settings as deemed. experimentally necessary. The Plexiglass arena allows careful monitoring of animal activity while allowing the animal to roam free across the experimental surface.

Creating Microclimates for Insect Subjects

Using TECA’s Gradient Bar System, a biology department at a U.S. university created a temperature preference device for small insects.

The insects were infected with various pathogens. The researchers wanted to create an environment where the insects chose a temperature benefiting pathogen replication/transmission and not host survival, thus determining whether pathogens alter their hosts’ temperature preferences.

Insulating their petri dishes and setting the entire gradient machine inside a larger incubator, the researchers created a microclimate and had excellent control over temperature fluctuations.

TEMPERATURE GRADIENT

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.

BATTERY COOLING

R & D Battery Cooling:

In this example, the customer is using TECA’s AHP-1800CPV to keep a 60 pound lithium ion battery cool during R&D testing. This saves the customer the trouble of using a plate with pumped coolant to cool the battery, which was the original method.

The customer reports that upgrading to the TECA AHP-1800CPV “makes testing much easier”.

The AHP-1800CPV is the largest thermoelectric cold plate on the market with a plate surface area of 12.80 x 13.30 inches.  The large surface area and robust cooling power were ideal for this application.

FIBER OPTICS

A research and development team in Europe uses the TECA Model AHP-1200CPV Cold Plate with a TECA Model TC-1 Tube Chiller attached.

Their process is proprietary but involves optical material and measurements. The TC-1 Tube Chiller is designed to heat or cool fluid without introducing contaminants to the fluid.

The fluid flows through the flexible tubing (various tubing diameters are possible) within the plate surface.
