medical laboratory cooling histology samples cooling histology tissue samples

Department of histology in a major hospital needed a peltier cold plate to freeze tissue samples for examination. The Histology Division of the Department of Pathology places tissue samples from biopsies into a small block and fills it with wax. Several of these samples are then placed on one of the AHP-1200CP thermoelectric cold plates (Peltier cold plates) to “pull the heat” out of the wax so it gets really hard.

The near-frozen samples are then shaved down to the desired section (slice) using a Microtome (in picture). The thin sections are then placed in the water bath to warm up the remaining wax in order to remove it and then place the section on a slide for examination.

3D PRINTING

3D Printing Process:

3d printing

A customer heard about TECA’s Thermoelectric Cold Plates through word-of-mouth and placed an order within a week. The AHP-301CP Cold Plate is used in the customer’s 3D printing process. Parts are printed on an aluminum plate which is then set on the AHP-301CP Cold Plate.

As the AHP-301CP Cold Plate cools the aluminum plate, the 3D prints just pop right off of the aluminum plate. The customer is pleased with the performance, ease of use and low purchase price of this basic model.

The AHP-301CP series is replaced by the newer AHP-401CP series.

CANADIAN FOG BOX

Canadian Fog Box:

Below are few pictures of the “Canadian Fog Box” that our customer constructed using TECA’s AHP-300CP cold plates, power supply, and TC-3400 PID controllers.

The interior of the box is covered with mirror finished aluminum to reflect the ultraviolet rays from the bulb in the bottom. The top is normally closed as well. The interior ambient temperature of the box is maintained @ 122 °F. subjecting the 2 insulated glass units (laying at a 45° angle) to intense UV radiation similar to strong sunlight. The upper portion of the glass is chilled to 70 °F. by your cold plates. This is maintained for 1 week 24 hours/day.

The insulated glass unit is then inspected for any condensation inside where the cold plates contacted the glass. Any condensation indicates impurities present inside the unit, which indicated faulty materials containing volatile gasses, which would lead to premature window unit failure.

Any other ‘fog boxes’ use water flow cold plates to maintain temperatures. Our customer during a research found TECA’s cold plates and decided to give them a try to eliminate the hassle and mess of water plates.

The thermoelectric cold plates (Peltier cold plates) have performed excellently to date, reaching and maintaining the 70 °F. quickly and without incident.

TITER PLATE COOLING

The WWW brings many to TECA’s door. These particular customer requirements were filled by an AHP-300CP Peltier cold plate. He needed to control the temperature of a 96 well titer plate in a new product design. But he needed just a few things the standard unit didn’t provide and he didn’t need some that it did provide. He wanted a 24 VDC heat cool system with continuous fan operation and a custom tap pattern on the cold plate.

In short order the TECA sales team assigned a preliminary part number, passed the requirements through to engineering and together the first units were modified and shipped. This gave the customer plenty of time to work with the solid state cold plates and refine his requirements into the custom design he uses today.

The AHP-300CP series is now replaced by a newer and more efficient model the AHP-470CP series.

LOW TEMPERATURE CASCADE

Low Temperature Cascade

A cascade sandwich is what we called this that day, built using two AHP-300CP cold plates. The customer needed a fairly large mass cycle between two extremes. The mass and size of the load were limiting factors. The pictures and assembly look crude, and it was, but they were also effective.

It was determined that a final design based on standard components would be successful and it was.

The AHP-300CP series is now replaced by a newer and more efficient model the AHP-470CP series.

A company that offers a broad range of door and window components and related building products with proven product lines and a multi-state collection of modern manufacturing facilities uses the AHP-150CP in a Canadian Fog Box, for testing double pane windows for condensation.

The AHP-150CP has been replaced by a newer and more efficient model the AHP-250CP series.

INDUSTRIAL ADHESIVE COOLING

Industrial Adhesive Cooling:

These folks needed to cool a thick fluid that ends up being gaskets when robotically dispensed. A custom version of our AHP-1200CP fit the bill perfectly. Now the product is dispensed consistently because of the temperature control provided by thermoelectrics.

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

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.
