Standard COD Dissolver (6-well)By using microcomputer technology and reasonable design, six 250ml conical flasks can be heated and digested simultaneously. Fully following the HJ828+2017 national environmental standard method, using high-quality electric furnace wire for heating, with the correct heating power, and micro boiling for 2 hours.
HCA-100The standard COD digestion device adopts a specially designed electric furnace plate for heating, with uniform surface heating and fast heating and cooling speed. Simultaneously using large-diameter and high-power fans for cooling, the condensation effect is good.
Standard COD Dissolver (6-well)You can set the digestion time, display the digestion time countdown, and the instrument will automatically stop heating after digestion is complete. The instrument fan will continue to work for 1 hour before stopping, assisting in sample cooling. It can be left unattended.

Standard COD Dissolver (6-well)Using glass burr reflux tube instead of spherical reflux tube, and replacing circulating water cooling method with cold air water cooling technology, the operation is more convenient. The cooling part is mainly completed by burr condensation tubes and fan air cooling. The spherical 3 bubbles on the upper part of the condensation tube make the cooling effect better. The catalyst is added here to prevent the instantaneous volatilization of light components in the sample and can be covered with a volatilization cap. The lower part consists of three opposing cold bubbles protruding from the condenser wall in a "burr" shape on a plane, which increases the cooling area compared to a simple spherical condenser and can block the passage of volatile substances and steam. In addition, the cooling water in the upper spherical reflux tube and the fan inside the machine have a dual effect. The HCA-100 standard COD digestion device ensures the reflux cooling of the sample, and the upper inserted reflux tube is safer and more stable to use. Energy and water conservation have greatly improved the work efficiency of staff. Widely used in various environmental monitoring stations such as environmental protection departments, universities, sewage treatment plants, chemical plants, etc.
