Macherey-Nagel Heating Blocks

Heating Blocks by Macherey-Nagel are precision laboratory instruments designed for the controlled thermal digestion of water samples prior to photometric analysis. They are an essential component of standardized water testing workflows, especially for parameters that require high-temperature digestion.

Macherey-Nagel heating blocks are primarily used with NANOCOLOR® photometric test kits, enabling accurate and reproducible digestion for parameters such as COD (Chemical Oxygen Demand), total nitrogen, total phosphorus, heavy metals, and other analytes that require oxidative or acidic digestion.

The range includes compact and high-capacity models such as:

• NANOCOLOR Heating Block – Dedicated digestion unit with fixed temperatures (e.g. 100 °C, 120 °C, 148 °C, 160 °C) for routine water and wastewater analysis.

• VARIO Heating Block – Flexible, programmable heating block with adjustable temperature and time settings, suitable for a wider range of digestion protocols and research applications.

These heating blocks feature precise temperature control, uniform heat distribution, and high chemical resistance, ensuring consistent digestion conditions across all samples. Safety features such as overheating protection, insulated housings, and secure vial positioning make them suitable for daily laboratory use.

Macherey-Nagel heating blocks are fully compliant with ISO, DIN, and EPA digestion standards, making them ideal for environmental laboratories, water utilities, industrial quality control, and research institutions.
