Dry block heaters

OHAUS 1 Block Dry Block Heaters are versatile block heaters designed for reliable everyday laboratory use, holding one optional interchangeable modular block selected from over 40 choices that install without tools. Close tube-to-block contact enables maximum heat retention for efficient heating, with digital models offering exceptional temperature uniformity and stability for repeatable results (ambient +5°C to 120°C, ±0.2°C to ±1.5°C stability, ±0.2°C to ±0.4°C uniformity at 37°C) and non-digital models controlled by dual temperature-adjustment knobs providing an economical choice. Digital models feature easy-to-use touchpad controls with independent temperature and time displays, plus single-point calibration for matching the display to a known external temperature standard across three setpoints.

Key features:

• One interchangeable modular block, over 40 choices, tool-free

• Digital models: single-point calibration at three setpoints

• Temperature range ambient +5°C to 120°C depending on model

• Close tube-to-block contact for maximum heat retention

• Touchpad controls with independent temperature/time displays

Typical applications:

• Everyday laboratory sample heating requiring temperature stability

• Molecular biology protocols needing reliable, repeatable heating

• Single-block heating tasks in routine laboratory workflows

OHAUS 2 Block Dry Block Heaters are versatile block heaters designed for everyday use, holding two optional interchangeable modular blocks selected from over 40 choices that install without tools. Close tube-to-block contact enables maximum heat retention for efficient heating, with digital models offering exceptional temperature uniformity and stability for repeatable results (±0.2°C stability, ±0.1°C uniformity at 37°C, ambient +5°C to 120°C range) while non-digital models provide an economical alternative. The optional Heatblock with Heated Lid features a second heater in the lid to minimize condensation and protect sample integrity, and digital models include single-point calibration to match the display to a known external temperature standard at three setpoints.

Key features:

• Two interchangeable modular blocks, over 40 block choices, tool-free

• Digital models: ±0.2°C stability, ±0.1°C uniformity at 37°C

• Temperature range ambient +5°C to 120°C depending on model

• Optional heated lid minimizing condensation for sample integrity

• Single-point calibration at three temperature setpoints (digital models)

Typical applications:

• Sample heating requiring close tube-to-block thermal contact

• Molecular biology protocols needing condensation-free incubation

• General laboratory heating tasks requiring temperature stability

OHAUS 4 Block Dry Block Heaters are versatile and dependable block heaters delivering precise, reliable results, designed for flexibility with four optional interchangeable modular blocks selected from over 40 choices that install without tools. The four-block capacity lets users process multiple samples simultaneously with one device, with close tube-to-block contact enabling maximum heat retention for efficient heating, while digital models offer exceptional temperature uniformity and stability for repeatable results (ambient +5°C to 120°C, ±0.2°C to ±2.5°C stability, ±0.2°C to ±0.4°C uniformity at 37°C) and non-digital models provide an economical choice. Digital models include single-point calibration matching the display to a known external temperature standard at three setpoints, with easy touchpad controls and independent temperature/time displays.

Key features:

• Four-block capacity for simultaneous multi-sample processing

• Over 40 interchangeable modular block choices, tool-free

• Digital models: single-point calibration at three setpoints

• Temperature range ambient +5°C to 120°C depending on model

• Close tube-to-block contact for maximum heat retention

Typical applications:

• Multi-sample heating requiring temperature stability

• Molecular biology and diagnostic protocols with batch processing

• General laboratory heating tasks needing flexible block configuration

OHAUS 6 Block Dry Block Heaters process more samples with a large-capacity design that delivers precise, reliable results, holding one optional interchangeable modular block chosen from over 40 options that install without tools. The six-block capacity is a unique design for high-throughput applications, letting users process multiple samples simultaneously with one device, with close tube-to-block contact enabling maximum heat retention for efficient heating. Digital models include single-point calibration to match the display to a known external temperature standard across three setpoints, with easy-to-use touchpad controls and independent temperature/time displays, while robust non-digital models use dual temperature-adjustment knobs (ambient +5°C to 120°C, ±0.2°C to ±2.5°C stability, ±0.2°C to ±0.4°C uniformity at 37°C).

Key features:

• Six-block capacity for high-throughput, simultaneous sample processing

• Over 40 interchangeable modular block choices, tool-free

• Digital models: single-point calibration at three setpoints

• Temperature range ambient +5°C to 120°C depending on model

• Close tube-to-block contact for maximum heat retention
