Yetuo WXJ-III Microwave Digestion Instrument


Model: WXJ-III


Product Overview:


Widely applicable to the identification and management of water quality by environmental protection departments, water resources management departments, and public health departments at all levels. It can quickly and efficiently determine the chemical oxygen demand (CODCr), total phosphorus (TP), and total nitrogen (TN) in various surface water, domestic sewage, and industrial wastewater.


Product Features of Yetuo WXJ-III Microwave Digestion Instrument



Sealed digestion, overpressure protection, safe and reliable, with a buzzer indicating completion of digestion;


In CODcr analysis, it effectively inhibits the oxidation of chloride ions to chlorine gas by potassium dichromate;


When dissolving CODcr, it can resist interference from chloride ions;


Microwave energy heating method, with molecules rotating at high speed in the digestion system, resulting in rapid heating and low consumption;


There are ventilation openings at the bottom and top of the device for heat dissipation and exhaust;


● Note: The digestion tank is made of polytetrafluoroethylene and is implemented according to the specified reagents and reaction conditions. It cannot be used for other purposes
