Grant QBT1 Heat Block

• Molecular biology for DNA/RNA denaturation and enzyme reactions.
• Biochemistry for protein digestion and sample incubation.
• Microbiology for bacterial culture incubation and media preparation.
• Clinical diagnostics for sample pre-treatment and assay incubation.
• General laboratory heating for various small-volume experiments.

Typical Temperature Range

Units of this class commonly offer a range from ambient +5°C up to 150°C.

Temperature Stability

Precision models typically achieve stability of ±0.1°C at common setpoints like 37°C.

Block Capacity

This type of heat block is commonly configured for 24 x 1.5 mL Eppendorf tubes, though other block formats are available for different tube sizes.

Power Supply

Typically operates on a standard single-phase electrical supply, such as 230V, 50Hz, suitable for UK laboratories.

Footprint

Compact benchtop units, typically around 200mm x 180mm x 120mm (W x D x H).

Heating Rate

Units of this type commonly take approximately 30-45 minutes to reach maximum temperature from ambient.

• What types of samples can be processed in a heat block?

  Heat blocks are primarily designed for small-volume liquid samples contained in tubes, such as Eppendorf tubes, PCR tubes, or microcentrifuge tubes. They are ideal for applications requiring precise temperature control for reactions or incubations.

• How do I ensure temperature accuracy with a heat block?

• Can I use different tube sizes with this heat block?

• What maintenance is typically required for a heat block?

• Is this unit suitable for continuous operation?

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.
