Some researchers at Johns Hopkins have taken the AHP-1200CPV thermoelectric cold plate (Peltier cold plate) and are cooling protein crystallization in Teflon trays with a solution in them. They’ve used the remote sense feature by drilling a hole in Teflon tray and installing the sensor in there. Using it with internal sensor and the auto-tuning feature they have gotten the control they needed. The secret may have been in how well the Teflon tray is contacting the 2″ X 3″ plate, machined perfectly flat.

Cooling objects with concave bottoms minimizes the contact area and diminishes the cooling effectiveness.

MEDICATION STORAGE

Keeping medication at optimal storage temperature is very important.

A customized AHP-1200CPV thermoelectric cold plate (Peltier cooling plate) with plate that has grooves with various diameters to accommodate vials of different sizes and lengths was a perfect solution for the customer. Another feature of this custom thermoelectric cooling unit (Peltier cold plate) is tamper proof temperature controller.

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.

Our customer calls the ICE-160 Electric Ice Trays a “dramatic improvement”. He uses several in his medical practice.

From our customer: “We use the ICE-160 during the quality-control and graft-storage portion of our minimally-invasive hair transplant procedures. While hair transplant grafts are outside of the body, they are fragile and susceptible to damage from dehydration and other factors as they are separated from their blood supply. During this delicate phase of the hair transplant, the harvested follicular unit micrografts are now in a special physiologic holding solution at 4 °C using the thermoelectric ICE-160 before and after being counted and sorted and while they are awaiting implantation. This is a dramatic improvement over the use of traditional graft coolers using frozen water which need to be swapped out often during a long NeoGraft FUE hair transplant procedure.

We are confident that this method of graft storage ensures maximum graft viability and helps us maintain exceptional results for our hair transplant patients. The solid metal surface is simple to clean and disinfect after each procedure. Thank you for this great addition to our practice!”

HAIR REPLACEMENT PROCEDURE

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

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.

A medical device manufacturer uses a TECA Low-Temperature Cascade System in his design process. The Cascade System consists of a TECA Cold Plate and Cascade attachment. The system offers direct contact cooling to the customer’s load.

In this example, the customer was able to cool his load of Isopropyl Alcohol solution from +25 °C to -25 °C in about 35 minutes. Cooling to such low temperatures allowed the customer to package his very small , invasive medical device.

We received the following feedback from the customer: “I was eventually able to get it down to -38 °C at an ambient temperature of 26 °C. It beats the heck out of the system that is currently being used…This thing is working beautifully. Everyone is most impressed. Thanks!!!”

HEARING AID

A global leader in developing and manufacturing cochlear implant systems uses the AHP-1200CPV to cool down silicone molds after the curing process so the operators can safely handle the mold. So far the cold plate has been performing perfectly.

CASCADE COLD PLATE

Cascade Cold Plate:

Here’s a step by step of an AHP-1200CAS/CCP-22 Cascade system our engineers were playing with. They took a purple EasySep magnetic nano particle vessel, set it on the cascade, insulated it and then cycled it up and down for kicks. The curve shows the results. Faster times can be achieved by thinning out the plates and building the cascade into the AHP-1200CAS rather than having it as an option.

Talk to TECA engineers if your interested.

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.

TITER PLATE COOLING

Titer Plate Cooling:

titer plate cooling AHP-300CP

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.
