To separate fluids, the centrifuge spins samples at a fast rate, resulting in heavy components to migrate away from the center axis and lighter components to migrate towards the axis. Centrifuge devices are widely used tools in food processing and medical research for cellular, genetic and protein analysis. When designing laboratory and medical centrifuges, several design challenges must be considered.
Since proteins are extremely sensitive to environmental deviations, a temperature difference by as little as 6°C from the body temperature of 37°C, have a negative impact on cell health. If too cold, cell growth slows and if too hot, sensitive proteins begin to denature. Not only temperature needs to be controlled, also humidity, carbon dioxide and oxygen levels are important factors. Due to the limited space constraints within incubators, thermal solutions must have a compact form factor. Incubator manufacturers also face challenges related to airflow, moisture, dust and ease of cleaning.
New addition to the PowerCool Series, the DA-280 expands cooling capacity of this product family…
February 28, 2019 – Global technology leader Laird Thermal Systems has developed a large capacity direct-to-air thermoelectric cooler assembly that offers greater cooling capacity than traditional thermoelectric based systems. Designed for refrigeration of medical chambers and analytical storage compartments, the DA-280 thermoelectric cooler assembly is an alternate to smaller compressor based systems.
The DAT-029-12-02 is a thermoelectric based air conditioner designed to temperature control small chambers used in analytical and medical diagnostic instruments. The unique design offers premium fans pushing air across-high density heat sinks to minimize the number of air flow paths required to operate. The design utilizes custom thermoelectric modules to maximize cooling capacity with a high coefficient of performance. Moisture resistant insulation is used to keep condensation from penetrating the TEM cavity. The unit operates on DC and is designed for an indoor lab use environment.
The DA-160-24-02 is a Direct-to-Air Thermoelectric Assembly (TEA) that uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via conduction. Heat is absorbed through a cold plate and dissipated thru a high density heat exchanger equipped with an air ducted shroud and brand name fan. It has a maximum Qc of 160 Watts when ΔT = 0 and a maximum ΔT of 40 °C at Qc = 0.
The DA-135-24-02 is a Direct-to-Air Thermoelectric Assembly (TEA) that uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via conduction. Heat is absorbed through a cold plate and dissipated thru a high density heat exchanger equipped with an air ducted shroud and brand name fan. It has a maximum Qc of 135 Watts when ΔT = 0 and a maximum ΔT of 35°C at Qc = 0.
