Dry block heaters - 1 block

Ohaus Dry block heaters - 1 block for Application-Based Model Selection

This series is designed for sample incubation, enzymatic reactions, microbiology workflows, and routine laboratory heating tasks, where the right choice often depends on differences in block count, temperature range, footprint, and throughput. 

The close tube-to-block contact enables maximum heat retention, resulting in efficient heating. High-wattage, constant-temp. analog models are an economical option, while digital models offer exceptional temp. uniformity & stability for applications that require repeatable results. Units hold optional interchangeable modular blocks with over 40 options.

• Designed for reliable daily use in the laboratory. Digital and analog heating blocks guarantee exceptional temperature uniformity with excellent thermal stability.

• Guaranteed temperature accuracy. The digital models feature a unique single point calibration function that aligns the heating block display to a known external temperature reference for 3 temperature thresholds.

• The digital models are equipped with easy-to-use touch controls, with independent displays for temperature and time. The rugged analog models are operated with two temperature control knobs.

Product Q&A

What are Dry Block Heaters used for?

They are used for applications requiring precise temperature control, such as incubation of cultures, enzymatic reactions, immunoassays, boiling/fusing points, isothermal incubations, and nucleic acid denaturation.

What is the difference between digital and analog models?

Digital models provide precise temperature control, independent displays for temperature and time, touch controls, and single-point calibration for accuracy. Analog models are more economical, controlled with dual adjustment knobs, and may require an external thermometer for verification.

Can the heating blocks be interchanged?

Yes, optional modular blocks allow for over 40 interchangeable configurations to accommodate different tube sizes and lab applications.

How is temperature accuracy ensured?

Digital models include a single-point calibration feature that aligns the displayed temperature to an external reference across three thresholds, ensuring precise and repeatable results.

Are these units suitable for daily laboratory use?

Yes, both digital and analog models are designed for reliable, long-term daily operation with excellent thermal uniformity and stability.
