Grant Instruments Digital Dry Block Heater, Ambient +5 to 130°C 230V


A versatile general purpose system with 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.


  • High power heater for fast heat-up – 25ºC to 100ºC in only 15 minutes.
  • Simple-to-use rotor plus two keys provide access to the interactive interface for fast, accurate set-up and use
  • Clear digital display – easy to read from a distance for instant reassurance
  • Convenient timer facility, with audible buzzer, for reaction timing and function timing, e.g. delayed heater switch-on/turn-off
  • Wide range of interchangeable blocks enables you to mix and match sample tubes as desired – extraction tool supplied as standard for easy and safe removal of blocks.
  • Optional safety cover – protects samples from contamination and users from accidental contact with hot blocks
  • Overtemperature cut-out protects your samples and your workplace
  • High quality, robust construction in streamlined coolwall aluminium and chemical-resistant plastic – durable in demanding environments
  • Compact footprint to optimise use of benchspace
  • Options include blocks for 0.2 ml tubes, strips and 96-well microtitre plates used in molecular biology and biotechnology applications (QBD2 & QBH2 only)
  • Three programmable temperature/time segments plus end-of program segments (QBH2 only)
