KHCOD-12ZType GB Standard COD Dissolution and Reflux DeviceAnother innovation has altered the fixed heating power of conventional COD dissolvers, eliminating the issue of boiling over in summer and under-boiling in winter. Utilizing silicon-controlled rectifiers, the heating can be adjusted freely, ensuring optimal boiling results.
KHC0D-12ZThe new standard COD digestion device features a glass burr reflux tube instead of the spherical reflux tube, and replaces the recirculating water cooling method with air and water cooling technologies for more convenient operation. The cooling section is primarily completed by water-cooled burr condensers and fan air cooling. The upper part of the condenser has a spherical bubble shape, enhancing the cooling effect, where the catalyst is added, preventing the immediate volatilization of light components in the sample, and allowing for a sealing cap. The lower part is shaped like a "burr," with multiple opposite "cooling bubbles" extending from the condenser wall on a single plane, which increases the cooling area compared to a simple spherical condenser and can block the passage of volatile substances and vapors. This is further enhanced by the dual action of the cooling water inside the spherical reflux tube and the internal fan.KHC0D-12ZThe new standard COD digestion device ensures sample回流cooling with an inserted, threaded baffle回流 tube, offering enhanced safety and stability.
