Techne Dri-block DB3 Heat Block

• Sample incubation and preparation in molecular biology and biochemistry.
• Enzyme reactions and denaturation studies requiring precise temperature control.
• Boiling point determinations and general laboratory heating tasks.
• Microplate heating for assays and diagnostic procedures.
• Chemical synthesis and digestion processes in analytical laboratories.

Typical capacity

This class of heat block commonly accommodates up to three aluminium alloy insert blocks, allowing for simultaneous heating of multiple samples.

Temperature range

Units of this type typically operate from ambient temperature up to 100°C.

Temperature stability

For this class of equipment, stability is commonly within ±0.1°C to ±0.15°C at set temperatures.

Temperature setting resolution

A 0.1°C resolution is typically provided for precise temperature adjustments.

Heat-up rate

Units commonly heat from 30°C to 100°C in approximately 15 minutes.

Power supply

Typically, these units operate on standard laboratory mains power, commonly 230V, 50/60Hz in the UK.

Footprint

Benchtop units of this design are generally compact, requiring minimal laboratory space.

• What types of insert blocks are compatible?

  Dri-block heaters typically use interchangeable aluminium alloy insert blocks, which are available in various configurations to accommodate different tube sizes (e.g., microcentrifuge tubes, test tubes, PCR tubes).

• Is calibration required for these units?

• How is temperature controlled on these devices?

• What maintenance is typically involved?

• Can this unit be used for cooling applications?

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.
