The Benchmark BSH1001-E Digital Dry Bath provides accurate "set and walk away" digital temperature selection, eliminating the need for external thermometers and repetitive "fine tuning" of a temperature control knob. Simply enter the desired temperature on the digital touch pad and the Benchmark BSH 1001 E Dry Bath provides accurate temperature with real time monitoring that continuously maintains the selected temperature within ±0.2°C. In addition, a digital timer is built into the touch pad display. Although it is not designed to shut off the heater, it can be used to alert the user that a chosen time interval has timed out. The cavities of the high grade aluminum blocks are precision machined to match the conical size and shape of 0.5, 1.5, 2.0, 15 and 50ml tube sizes, providing unsurpassed temperature transfer. Assorted blocks are available for compatibility with nearly all common laboratory tubes and plates. Assorted and custom blocks are sold separately. BSH-1001-E dry bath offers a built-in user recalibration function, to guarantee long term temperature accuracy. Each dry bath includes an easy to use block lifter, with a temperature insulated handle for quick, convenient exchange of blocks, even while they're still hot.
