COLD PROBE

Cold Probe Medical Application:

A Medial Doctor was interested in a Peltier based “Cold Probe” to anesthetize the skin prior to treatment. He wanted an instrument that ran on batteries based around the Otoscope or the Ophthalmoscope with interchangeable heads. It was a medical application, a prototype and a long shot one at that.

He came to TECA with some rather limiting criteria to do a big job considering the load human skin presents. We did our best and gave the good Doctor his cold probe. We designed it, packaged it, powered it and built it. But not many folks really needed it. Not a complete market success but a technical one.

PORTABLE MEDICINE COOLER

Portable Medicine Cooler:

Portable medicine cooler needed for carrying emergency intravenous solutions, all components must be enclosed within the case. TECA designed a custom thermoelectric (peltier) based cold plate built into a Pelican™ Box.

TECA is developing this product for a new customer. We have taken a standard Pelican™ Box and configured a battery powered thermoelectric cooling system which is installed totally inside. This cooled box is for the purpose of transporting up to 4 liters of emergency intravenous solutions safely.

There are fitted compartments inside as well for transporting other necessary items for patient care. Since nothing is exposed or protruding from the box, our customer has ended up with a good looking and very rugged, functional thermoelectric product.

NEUROSCIENCE RESEARCH

At a prominent U.S. university, neuroscience research team choose TECA’s economical AHP-270CP Cold Plate.

The customer reports: “We cool a fly to 8 deg Celsius, and also use vacuum to attach it to the device during a brain dissection procedure. Essentially, the cooling is anesthetizing the fly, making it possible to attach the fly to the dissecting chamber in a very precise manner, using a manipulator (also in the picture).” The AHP-270CP is a great solution because it is small, inexpensive and yet offers reliable and effective cooling on the bench top.

FLOW CHEMISTRY / OEM PRODUCT

flow chemistry, cascaded thermoelectric cold plate

A European company specializing in equipment for the continuous flow chemistry market required extreme temperatures for a new product. Integrating a customized version of TECA’s Liquid Cooled Cascaded Cold Plate made the customer’s product possible: they are able to reach temperatures from minus 70 °C to plus 80 °C.

The customer reports that their new continuous flow reactor allows for the use of flow chemistry in many applications, achieving quicker results safely and with better control.

TISSUE DISSECTION

Tissue Dissection Application:

AHP-1200CAS used in tissue dissection

We used TECA’s AHP-1200CAS three stage cascaded thermoelectric cold plate system to facilitate dissection of frozen human postmortem brain slices for extraction of protein for Proteomics research. Because we were trying to select specific regions without damaging the rest of each small specimen, it was important for us to maintain the integrity of the specimen during dissection.

Working in a lab at normal room temperature, we found that a constant temperature of -18 °C was ideal for this work (-20 °C was too cold, and warmer than -18  °C made the tissue start to melt). It would have been impossible to maintain such a precise temperature outside of a Cryostat without the cold table. It was immensely easier to perform the dissection on the cold table, and of course also much easier to wipe down the cold table than to clean a Cryostat.

COOLING FLUID FLOW

Cooling Fluid Flow:

Chilling liquids being circulated by a peristaltic pump under ultra-clean conditions. When handling and processing various fluids in laboratory and electronic environments cleanliness is a must. Peristaltic pumps have been developed for the purpose of creating a fluid flow without contacting the fluid itself. TECA developed a liquid chiller to cool fluids, while satisfying the same cleanliness requirements.

The solution, based on our successful cold plate product line, has proven to be versatile and effective. Pictured here is the first prototype of a multiple-pass tube cooler for use with a peristaltic pump. Applications range from laboratory to medical to industrial.
