Grant QBT1 Heat Block

• Incubation of samples in molecular biology for DNA/RNA denaturation or enzyme reactions.
• Sample preparation in biochemistry for protein digestion or inactivation.
• General laboratory heating for maintaining samples at a constant temperature.
• Boiling point determinations and other temperature-dependent assays.

Typical capacity

Commonly accommodates 24 x 1.5ml tubes, though other block configurations may exist for this class of equipment.

Temperature range

Typically ambient +5°C to 100°C, providing precise temperature control for various applications.

Temperature stability

For this class of equipment, stability is typically ±0.1°C, ensuring consistent heating.

Power supply

Commonly 230V, 50Hz, single phase, suitable for standard UK laboratory outlets.

Heating method

Dry block heating, utilising removable aluminium blocks for efficient heat transfer without liquids.

Footprint

Typically compact, designed for benchtop use in laboratories where space is at a premium.

• What are the advantages of a dry block heater over a water bath?

  Dry block heaters offer precise temperature control, eliminate the need for water or oil, and reduce the risk of contamination. They are also generally cleaner and require less maintenance.

• Can I use different tube sizes with this unit?

• Is this unit suitable for continuous operation?

• What maintenance is typically required for a dry block heater?

• Does this unit require calibration?

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.
