Maple lab Scienfific - Maplelab Scientific Block Heater

• Sample preparation in analytical chemistry, biochemistry, and molecular biology.
• Enzyme reactions and denaturation studies requiring precise temperature control.
• Incubation and activation of cultures in microbiology laboratories.
• Digestion procedures for environmental and food testing.
• Boiling point determinations and melting point studies.

Typical capacity

This class of block heater commonly accommodates 1-4 interchangeable heating blocks, each designed for various tube or vial sizes (e.g., 0.2ml PCR tubes, 1.5/2.0ml microcentrifuge tubes, 15ml/50ml centrifuge tubes).

Temperature range

Units of this type typically offer a temperature range from ambient +5°C up to 100-150°C, with some models reaching higher temperatures.

Temperature stability

Commonly, these units provide temperature stability of ±0.1°C to ±0.5°C, crucial for sensitive applications.

Heating rate

The heating rate for this equipment class is typically several degrees Celsius per minute, depending on the target temperature and block material.

Power supply

For the UK market, these units commonly operate on a standard 230V, 50Hz single-phase power supply, with power consumption typically ranging from 150W to 400W.

Control interface

Most block heaters feature a digital display and keypad for precise temperature setting and monitoring, often with timer functions.

Safety features

Typically includes over-temperature protection and fuse protection to ensure safe operation.

• What types of blocks are compatible with this unit?

  Compatibility depends on the specific manufacturer and model. Buyers should verify with the seller if the unit includes blocks and what types of tubes or vials they are designed for, or if universal blocks are available.

• Is calibration required for accurate temperature control?

• What maintenance does a used block heater typically require?

• Can this unit be used in a fume hood?

• What is the typical footprint of such a unit?

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.
