Dry Block Heaters

Product Announcement from Thermo Fisher Scientific - Thermo Scientific Baths, Circulators & Chillers

Thermo Scientific* analog and digital dry baths offer precise temperature control resolution and a much smaller footprint than a general purpose incubator and can be used at temperatures up to 130°C.

These analog and digital dry block heaters feature a built-in temperature-sensing probe for improved temperature accuracy and control. Compact design saves valuable bench space. The anodized aluminum modular blocks accommodate test tubes, square cuvettes, microcentrifuge tubes, 96-well plates, PCR plates and conical bottom centrifuge tubes. Dry block heaters hold 1, 2, 3, 4, and 6 interchangeable modular blocks to accommodate a variety of vessels.


  • Number of block configurations meet the needs of virtually any application
  • Compact design is ideal for tight space locations
  • Digital units utilize a PID microprocessor controller with digital temperature set and easy-to-read LED display for accurate and reproducible temperature control
  • Analog units feature bimetallic dual thermostat control
  • Powder-coated steel body construction ensures durability
  • Chemically resistant design meets the needs of the laboratory environment

Analog Units

  • Ideal for fixed temperature applications
  • Temperature control at 37°C: ±3.5°C, with uniformity of ±0.5°C
  • Dual temperature control for precise control over two ranges: low range slightly above ambient to 60°C, high range 50° to 130°C
  • Read thermometer and adjust knob controller to desired setpoint

Digital Units

  • Temperature control at 37°C: ±0.5°C, with uniformity of ±0.4°C
  • Setpoint easily adjusted via up and down arrow keys on front of unit
  • Modular block mounts on a single temperature probe in Dry Block Heater bottom, for optimum temperature accuracy and control
