Thermo Fisher Scientific - Thermo Scientific Heat Block

• Used for precise temperature control of samples in test tubes, vials, and microplates.
• Commonly employed in molecular biology for DNA denaturation and enzyme reactions.
• Utilised in clinical laboratories for sample incubation and coagulation studies.
• Applied in biochemistry for protein digestion and cell culture maintenance.
• Suitable for general laboratory heating and sample preparation tasks.

Typical temperature range

Ambient +5°C to typically 100-150°C, depending on the specific model.

Block capacity

Units of this type commonly accommodate multiple interchangeable blocks, holding various tube sizes (e.g., 0.2ml, 0.5ml, 1.5ml, 2.0ml) or microplates.

Temperature stability

Typically ±0.1°C to ±0.5°C, crucial for sensitive applications.

Power supply

Commonly 230V, 50/60Hz for UK operation, with power consumption varying by model, typically 100-300W.

Heating method

Utilises dry heat, eliminating the need for water or oil baths.

Control interface

Typically features a digital display and keypad for temperature setting and monitoring.

• What types of samples can be heated in a Thermo Scientific Heat Block?

  These units are designed to heat samples contained in standard laboratory tubes (e.g., Eppendorf tubes, centrifuge tubes), vials, and sometimes microplates, depending on the specific block fitted.

• Are the heating blocks interchangeable?

• What maintenance is typically required for a used heat block?

• Can this unit be calibrated?

• What safety features are commonly found on these units?

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.
