CUSTOM COLD PLATE

Custom Cold Plate Application:

The people at MIT who wanted a custom cold plate with plain black anodized cold plate never did tell us what it was for. We think maybe they are using it to calibrate or adjust infra red temperature detectors. We could be wrong. They might have thought it just looked cool.

For whatever reason, they told us what they wanted and we did our best to meet their requirement.

NEUROSCIENCE RESEARCH

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.

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.

LIQUID CHILLER COLD PLATE CASCADE

Liquid Chiller Cold Plate Cascade:

Here are pictures of the TLC-900 thermoelectric liquid chiller with LHP-150CP Peltier liquid cooled cold plate set up run in the lab. The “load” is a plate with 10 power resistors mounted to the top and a series of thermocouples measuring the surface of the LHP-150CP’s thermoelectric cold plate.

During the test the power to the resistors is increased in steps with enough time in between for the temperatures to stabilize. Plotting the data resulted in performance curves. The test was made with the load insulated and with the load simply covered.

Later on we used a TLC-900CAS, a version of the TLC-900 made specifically for running and controlling secondary cold plates like the LHP-150CP and ran some step, ramp and soak profiles.

STIRRING COLD PLATE

Stirring Cold Plate:

A Peltier stirring cold plate was needed to cool liquid inside a standard 1000 ml plastic tank and maintain the class 100 clean room rating. They desired a custom designed thermoelectric stirring cold plate with integral variable stir speed control, temperature control, alarm and remote sense capability.

TECA is glad to participate in custom and OEM product development. Over the years we have come up with some innovative and novel solutions for our customers. This product was developed from scratch for a start-up company in the field of pharmaceutical development. This TECA cold plate apparatus was designed and built for use in a clean room facility. The controls are ergonomic. The user can easily adjust controls for stir speed, timing and temperature even while wearing clean room garb and sterile gloves.

COOLING FLUID FLOW

Cooling Fluid Flow:

A customer needed to cool high pressure flow of fluid in a single pass. Using expanded Aluminum foam and attaching it to the surface of AHP-301CP thermoelectric cold plate (peltier cold plate) provided a way to maximize the thermal contact surface and eliminated the need to complex fluid path and larger cold plate.

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.

R & D LABORATORY

R & D Laboratory:

r & d laboratory
An R&D laboratory needed to quickly cool beakers of high-concentration sucrose samples to 10 °C.  The customer reports that using TECA’s AHP-800MSP Magnetic Stirring Cold/Hot Plate system has been successful.

The customer has different sizes of samples, which are accommodated by TECA’s sleeve accessories. The customer uses 2L, 1.5L, 1L and 800mL sleeves at different times with the AHP-800MSP system. The sleeves are easy to switch in and out and add versatility to the system.

In fact, unique to this product is the adjustable nature of many of its features: stir-bar speed, fan speed (for noise reduction), and temperature sensing (internal or external).
