Grant QBD2 Dry Block Heater

• Molecular biology applications such as DNA denaturation, enzyme reactions, and sample incubation.
• Clinical laboratory procedures including blood sample heating and coagulation studies.
• General laboratory heating for reagent warming, digestion, and extraction processes.
• Environmental sample preparation requiring precise temperature control.

Typical block capacity

This class of dry block heater commonly accommodates 1 to 4 interchangeable blocks, each designed for various tube or plate formats.

Temperature range

Units of this type typically offer a temperature range from ambient +5°C to 100°C or 130°C.

Temperature stability

For this equipment class, temperature stability is commonly ±0.1°C to ±0.5°C.

Temperature uniformity

Uniformity across the block is typically ±0.1°C to ±0.5°C at 37°C.

Power supply

Commonly operates on a standard laboratory power supply, typically 230V, 50/60Hz, drawing around 150-300W.

Heating rate

Units typically heat from 20°C to 100°C in approximately 10-20 minutes, depending on the block and load.

Footprint

For a two-block unit, the footprint is typically compact, often around 200mm x 250mm x 100mm (W x D x H).

• What types of blocks are compatible with the QBD2?

  The QBD2 typically uses custom-made, interchangeable aluminium blocks designed to fit various tube sizes (e.g., 0.2ml, 0.5ml, 1.5ml, 2.0ml microtubes) and microplates. Buyers should confirm the specific blocks included or available for this unit.

• Is calibration required for dry block heaters?

• What is the advantage of a digital dry block heater over an analogue one?

• Can this unit be used for cooling applications?

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

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.
