Grant Instruments QBD1 Heatblock

• Sample preparation in molecular biology, such as DNA denaturation and enzyme reactions.
• Incubation and activation of cultures in microbiology laboratories.
• Chemical reactions requiring precise temperature control and consistent heating.
• Digestion procedures for environmental and food testing.
• Boiling point determinations and melting point studies in analytical chemistry.

Typical capacity

Units in this series typically accommodate multiple interchangeable blocks, each holding various tube or vial sizes (e.g., 0.2ml PCR tubes, 1.5ml/2.0ml microcentrifuge tubes, 15ml/50ml centrifuge tubes).

Temperature range

Commonly, these units offer a temperature range from ambient +5°C up to 100°C or 130°C, depending on the specific model and block.

Temperature stability

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

Temperature uniformity

Across the block, uniformity is commonly ±0.1°C to ±0.5°C, crucial for reproducible results.

Power supply

Units are typically powered by a standard single-phase electrical supply, commonly 230V, 50/60Hz for the UK market.

Heating rate

The heating rate to 100°C is typically a few minutes, depending on the block material and ambient conditions.

Control interface

Digital control with a clear display is commonly found on units of this type, allowing for easy temperature setting and monitoring.

• What types of blocks are compatible with the Grant QBD series?

  The Grant QBD series typically uses interchangeable aluminium blocks designed to fit various tube and vial formats. Buyers should confirm specific block compatibility with the seller.

• Can this unit be used for cooling applications?

• Is calibration required for these units?

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

• How do I choose the correct block for my tubes?

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.
