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.

FIBER OPTICS

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.

PHARMACEUTICAL LABORATORY

Pharmaceutical Laboratory:

Keeping drugs cool on the bench

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.

LABORATORY APPLICATION

Laboratory Application:

In March our customer said: “We are most likely going to soon order 1 of the AHP-301CPV.”

First though, can you please provide a quote on the manufacture of a top plate? We would like to fit:

2 x 500 mL Schott bottles (the one I measured was 86mm diameter)
2 x 250 mL Schott bottles (the one I measured was 68mm diameter)
2 x 50 mL Schott bottles (the one I measured was 46mm diameter)

I’d guess that Schott do not make their bottles to too tight specifications, so we would need to allow some room for tolerances. What do you think? These could be arranged in any way that fit best and that minimized any top plate overhang over the cold plate beneath. We can foresee out-growing the 50 mL bottles, so ideally would like the ‘walls’ surrounding the 50 mL wells to be thick enough to later be drilled out so that the wells can accommodate 100 mL Schott bottles (the one I measured was 56mm diameter). The height of the top plate (i.e. depth of the wells) only need be about 70 mm. For the current application, we only need to chill to about 5 deg °C. Does the range we are interested in affect anything?

In May we shipped the custom “Beaker Block: and AHP-301CPV.

In this example of an AHP-1200CP application a box surrounds the cold plate area. Materials are set directly upon the cold plate and the lid is closed. The material is cooled and temperature controlled without the large air cooling refrigerator.

HAIR REPLACEMENT PROCEDURE

Hair Transplant Procedure, Follicular Unit Transplant/Extraction (FUT/FUE):

hair transplant procedure

A group of physicians pioneered a hair replacement procedure using TECA’s AHP-1200CPV Cold/Hot Plate. The AHP-1200CPV is a Peltier cold plate. In the photo provided by TECA’s customer, the cold plate keeps hair transplant grafts cool in a solution during the patient’s procedure. The convenience of the AHP-1200CPV cold plate’s built-in temperature controller allows the technician to easily program it to maintain the desired set point.

The AHP-1200CPV is capable of reaching temperatures as low as -15 °C. In the photos here, the set point is programmed to 5 °C. The AHP-1200CPV has an integral universal power supply, so it can be used with any input voltage range from 100 to 240 VAC.

ELECTRONIC TEST STATION

Electronic Test Station:

An aerospace contractor was interested in a large cold plate for the testing of electronic components. We first offered them the AHP-1200CPV but they responded that the AHP-1200DCP was more the size they wanted. Could we change it to a single plate? Well, we couldn’t change the plate size but we could add an accessory plate which was larger. And we could build the unit with one controller including all of the standard options.

Now they are using the 12” x 18” custom accessory plate and a special AHP-1200DCP to test electronic amplifiers by ramping the temperature up and down between +10 °C to +70 °C. A custom solution at very nearly standard product price to fill a not so unusual need.

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.
