A broad temperature range, to 150ºC, makes the Digital Dry Baths useful for a variety of applications in molecular biology, histology, clinical, environmental and industrial laboratories. A microprocessor regulates the high wattage heaters in the baths to provide precise, accurate control. The desired temperature is easily set using the arrow keys on the control panel while values are shown on the digital display. No checking of a thermometer and readjusting temperature is necessary. The user calibration feature allows for calibration to in house standards when required. Additionally, there is an RS232 port for recording block temperature activity. The block chamber is constructed of stainless steel, acting as a heat sink and providing a uniform transfer of heat from the heating elements to the interchangeable blocks. The resulting block uniformity ensures all samples receive the same temperature treatment, regardless of their block position. The AccuRack tube rack has capacity for up to 20 x 1.5mL tubes. The rack is self standing for use as a workstation and can be directly loaded into the block for tube placement and extraction. Insulated handles protect the user from the high block and sample temperatures. The AccuRack is safe for use up to 150°C and is autoclavable. Two Digital Dry Bath models are available. The single block unit will accept all of the standard blocks. The dual block unit accepts two standard blocks or one specially designed dual block. Each Dry Bath is supplied with a block lifter. Blocks sold separately.
