Grant Instruments QBD1 Digital Dry Block Heater

• Sample preparation in molecular biology, such as DNA denaturation and enzyme reactions.
• Incubation and activation of cultures in microbiology.
• Digestion procedures in environmental analysis and food testing.
• Coagulation studies in clinical diagnostics.
• General laboratory heating for a variety of small-scale reactions and assays.

Typical temperature range

Ambient +5°C to 100°C, commonly with stability of ±0.1°C.

Block capacity

This model typically accommodates a single interchangeable block, suitable for various tube and vial formats.

Temperature control

Digital PID control is standard for precise temperature management.

Power supply

Commonly 230V, 50/60Hz for units sold in the UK, with power consumption typically in the range of 150-250W.

Heating rate

Typically heats from ambient to 100°C in under 20 minutes, depending on the block and load.

Footprint

For this class of equipment, units are generally compact, suitable for benchtop use, with dimensions around 200mm (W) x 250mm (D) x 100mm (H).

• What types of blocks are compatible with the Grant QBD1?

  The Grant QBD1 is designed for use with specific Grant QBD series interchangeable blocks. Buyers should confirm the availability of suitable blocks for their specific tube or vial sizes with the seller.

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

• Is this unit suitable for continuous operation?

• How do I ensure temperature accuracy for my specific application?

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.
