Thermoelectric cooling semiconductor modules available in new configuration

A line of thermoelectric cooling semiconductor modules feature a porch configuration for easier installation and optimum solder contact. The 4-mm-wide ceramic porch extends between the positive and negative contacts, allowing for clean lead attachment and preventing accidental pellet contamination. Available in sizes of 40 x 44 or 30 x 34 mm, the Z-max modules are manufactured through a metallurgical process that produces a robust positive semiconductor chip, resulting in a temperature differential of 4°C. Applications include DNA thermocyclers, blood analyzers, blood reagent refrigeration units, therapy blankets, and devices without sufficient space for standard compression refrigeration. Tellurex Corp., 1248 Hastings St., Traverse City, MI 49686.
