Grant Bath QBT1

• Incubation of samples at controlled temperatures for various laboratory protocols.
• Enzyme reactions and denaturation/activation steps in molecular biology.
• Sample pre-heating prior to assays or analytical procedures.
• Maintaining consistent temperature during experimental protocols and sample preparation.
• General wet lab workflows requiring precise temperature control without the use of water.

Typical capacity

Dry block heaters of this class commonly accommodate one or more interchangeable blocks, each holding various tube or plate formats (e.g., microcentrifuge tubes, PCR tubes, cryovials).

Temperature range

Units of this type typically offer a controlled temperature range from ambient +5°C up to 100-150°C, depending on the model and block material.

Temperature stability

For this class of equipment, temperature stability is commonly around ±0.1°C to ±0.5°C, crucial for sensitive reactions.

Power supply

Dry block heaters typically operate on a standard single-phase electrical supply, commonly 230V, 50Hz for the UK market.

Footprint

These units are generally compact benchtop devices, designed to occupy minimal laboratory space.

Control interface

Most units feature a digital display and push-button controls for setting and monitoring temperature.

• What is the primary advantage of a dry block heater over a water bath?

  Dry block heaters offer precise temperature control without the risk of contamination from water, require less maintenance, and are generally more compact. They eliminate the need for water, reducing evaporation and potential for microbial growth.

• Can I use different types of sample tubes with this unit?

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

• Is this unit suitable for high-throughput applications?

• What safety considerations are there when operating 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.
