Techne Dri-Block heater with sample concentrator

• Used for consistent and precise heating of samples in laboratory settings.
• Commonly employed in molecular biology for DNA denaturation and enzyme reactions.
• Utilised in microbiology for incubation of cultures and media preparation.
• Applied in analytical chemistry for sample pre-treatment and solvent evaporation.
• Suitable for various industrial quality control processes requiring controlled heating.

Typical capacity

For this class of equipment, units commonly accommodate multiple interchangeable blocks, each holding varying numbers of tubes (e.g., 24 x 1.5ml, 15 x 15ml, 6 x 50ml).

Temperature range

Typically, these units offer a temperature range from ambient +5°C to around 100-130°C, with precise temperature control.

Temperature stability

Commonly, temperature stability is ±0.1°C to ±0.5°C, ensuring uniform heating across samples.

Power supply

Units of this type commonly operate on standard laboratory power supplies, typically 230V, 50/60Hz, with power consumption varying by model.

Heating rate

The heating rate for this equipment class is typically several degrees Celsius per minute, depending on the block and set temperature.

Sample concentrator functionality

When equipped with a concentrator, units typically feature gas inlets for inert gas (e.g., nitrogen) flow over samples to accelerate evaporation.

• What is the primary function of a Dri-Block heater?

  A Dri-Block heater provides a stable and uniform temperature environment for heating samples in test tubes, vials, and microplates, eliminating the need for water or oil baths.

• How does a sample concentrator enhance the unit's utility?

• Are the heating blocks interchangeable?

• What maintenance is required for a Dri-Block heater?

• Can this unit be used for sterilisation?

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.
