• QB Series Dry Block Heating Systems

    A versatile general purpose system with two removable/interchangeable blocks and a comprehensive specification to suit most dry block heating applications in the laboratory.

    • Temperature range ambient +5ºC to 130ºC, with rapid heat-up time
    • Stability: ±0.1ºC
    • Uniformity: ±0.1ºC
    • Digital temperature control for optimal precision
    • Range of convenient features including alarms, single and dual point calibration, programmed start/stop, ‘offset’ for known sample temperature variation and choice of external or internal probes
    • External probe available for accurate in-sample or in-block temperature control
    • Includes block removal tool for easy and safe removal of blocks.


    A source of precision temperature control for general, routing applications and sensitive analytical procedures including enzyme digestions, enzyme activity studies and nucleid acid hybridisations.
