Pierce Reacti-Therm 18840 Heat Block

• Sample preparation in analytical chemistry laboratories.
• Incubation and reaction heating for biochemical assays.
• DNA denaturation and enzyme kinetics studies.
• Evaporation of solvents from samples.

Typical temperature range

Ambient to approximately 150-200°C, depending on the specific model and block.

Block configuration

Commonly accepts interchangeable aluminium blocks designed for various tube sizes (e.g., microcentrifuge tubes, test tubes, vials).

Number of block positions

Typically features one or more positions for heating blocks, often accommodating multiple samples simultaneously.

Temperature stability

For this class of equipment, stability is generally within ±0.1°C to ±0.5°C.

Power supply

Commonly operates on standard laboratory power, typically 230V, 50Hz for UK use.

Footprint

Units of this type are generally compact, designed for benchtop use in laboratories.

• What kind of samples can be processed with a heat block?

  Heat blocks are typically used for heating small-volume samples in tubes or vials, common in molecular biology, chemistry, and clinical labs.

• Are heating blocks included with the unit?

• What maintenance is required for a heat block?

• Can this unit be used for cooling applications?

• What safety considerations are important when using a heat block?

Dry block heaters are valued in laboratory and biotech settings for reliable, uniform sample heating. Buyers typically appreciate their compact design, precise temperature control, and ease of use. When purchasing used units, checking calibration accuracy, element functionality, and power cord condition remains important. Industry sentiment favours models with consistent performance records and minimal maintenance history. Common strengths include rapid heat-up times, good temperature stability, and compatibility with standard microtubes and vials. Corrosion resistance in the heating block surface is often considered desirable for longevity.
