Ohaus HB4AL Dry Block Heater

The Ohaus HB4AL Dry Block Heater is engineered for dedicated daily laboratory tasks, excelling in applications that necessitate precise temperature stability. This versatile device accommodates four modular blocks, easily interchangeable from a selection of 40 options. The intimate block-tube contact ensures optimal heat retention, maximizing heating efficiency.

The analog models serve as a cost-effective choice with a controlled temperature range from +5°C above the ambient up to 100°C in the low range, and 75°C to 150°C in the high range, using two adjustable knobs. In contrast, the digital versions cater to those seeking reproducibility, offering a range from 5°C above ambient temperature to 120°C, with intuitive touch pad controls and independent, legible LED displays for precise temperature and timing, including an alert system.

The device boasts remarkable temperature uniformity and exceptional thermal stability, alongside a unique single-point calibration feature for accurate temperature readings (in digital models).

Applications: Ideal for culture incubation and activation, enzymatic reactions, immunological analyses, determining melting/boiling points, isothermal incubation, and nucleic acid denaturation.
Display Options: Features an LED display for digital models and dual adjustment knobs with clear markings for analog variants.
Operation: Comes with a removable three-wire cord and plug. Analog models necessitate external thermometers for accurate setpoints.
Structure and Construction: Built with durable painted steel housing and a support bar with a secure fixing knob. Digital models include a keypad control and audible alarm for enhanced monitoring.
