• CH3-150 Combitherm-2 dry block heating/cooling system

    The Grant-bio CH3-150 Combitherm-2 dry block heating cooling system is specially designed to thermostabilise materials at temperatures from –3°C to +150°C according to methods of analysis.

    • Stability: ±0.1ºC
    • Independently regulated heating and cooling blocks in the same unit
    • Digital timer with sound alarm: 1 min to 99 h 59 min (increment 1 min)
    • User adjustable programmes (temperature and time): 16 (heating) + 16 (cooling)
    • Digital temperature control for optimum precision
    • Temperature Calibration Function
    • Protective lid

    The CH3-150 has seven interchangeable blocks available. Custom blocks available on request.
