COD Digester

This advanced COD digestion reactor is specially developed for pretreatment and chemical oxygen demand testing of water samples in laboratory scenarios. It adopts premium microcrystalline heating panel as the core heating component, which can withstand high temperature up to 800°C, featuring outstanding thermal stability and long service lifespan.

The microcrystalline heating platform delivers evenly distributed surface temperature, effectively avoiding local overheating and temperature deviation during experiments. With rapid heating and natural cooling characteristics, it shortens instrument preheating time and post-test cooling period, greatly improving working efficiency for continuous batch sample processing.

Inside the device, high-temperature resistant ceramic fiber heating disc is adopted as the heat source. The optimized structural design effectively reduces heat dissipation loss from the base and shell, forming a balanced and stable temperature field across the entire working area. It can steadily maintain the constant temperature environment required for COD digestion reactions.

Uniform and stable thermal field ensures reliable experimental conditions, enabling high consistency and good repeatability of detection data. The whole machine features high temperature resistance, corrosion resistance and anti-scald performance, fully adapting to long-term daily laboratory operation and frequent batch digestion tasks.

It is widely adopted by environmental monitoring stations, sewage treatment enterprises, industrial labs, universities and research institutes for routine COD digestion and water sample pretreatment. Thanks to premium material configuration, energy-saving heating design and stable constant temperature performance, it has become standard essential equipment for professional water quality laboratories.
