Grant QBT1 Heat Block

• Sample preparation in molecular biology, biochemistry, and clinical laboratories.
• Enzyme reactions and denaturation studies requiring precise temperature control.
• Incubation of samples for various analytical procedures.
• Digestion and extraction processes in environmental and food testing.

Typical capacity

This single-block unit typically accommodates one interchangeable aluminium block, suitable for various tube sizes (e.g., microcentrifuge tubes, PCR plates, test tubes) depending on the block fitted.

Temperature range

Units of this type commonly offer a temperature range from ambient +5°C up to 100°C or 130°C, with precise digital control.

Temperature stability

For this class of equipment, temperature stability is typically ±0.1°C to ±0.5°C, ensuring consistent heating.

Heating rate

The heating rate commonly allows for rapid heating to set temperature, often reaching 100°C in under 15 minutes.

Power supply

Units are typically powered by a standard single-phase electrical supply, commonly 230V, 50/60Hz, with a power consumption of around 150-200W.

Footprint

Dry block heaters like the QBT1 are compact benchtop units, typically measuring around 150-200mm (W) x 200-250mm (D) x 80-100mm (H).

• What type of blocks can be used with the Grant QBT1?

  The Grant QBT1 is designed to accept interchangeable aluminium blocks. Buyers should confirm with the seller which specific block, if any, is included or if it is compatible with standard Grant QBT series blocks.

• Is temperature calibration required for this unit?

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

• Can this unit be used for cooling applications?

• 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.
