KHC0D-8K typeTemperature controlled typeCODDissolving reflux device

KHC0D-8K typeNational Standard LawCOD digestion reflux deviceBy using microcomputer technology and reasonable design, the temperature of the electric furnace plate is displayed on the LCD screen, and the digestion time is also displayed, which can be used forEight 250ML conical flasks were heated and refluxed simultaneously for digestion. Fully following the HJ828-2017 national new standard method, the microcrystalline glass tabletop is used, high-quality electric furnace wire is selected, the correct heating power is applied, and micro boiling is ensured for 2 hours.

KHC0D-8K typeNational Standard LawCOD digestion reflux device,Another innovation, adoptingtransferWarm heating, maintaining the temperature not exceeding the boiling temperature, firstly saves energy, and secondly, when the sample boils, it will not continue to heat up and adjust the pressure and temperature to allow the sample to boil in the desired state. Simultaneously, dual fans are used for cooling to achieve the desired effect.

KHC0D-8K typeNational Standard LawCOD digestion reflux deviceSelect a specialized electric heating plate for heating,Microcrystalline glass countertop, overall structure, reasonable isolation design, microcrystalline heating plate is a single piece, easy to install and replace electric furnace plateWhen heating, the surface of the electric furnace plate heats up evenly, and the heating and cooling rates are fast. The sample solution accidentally drips onto it, making cleaning very convenient.

KHC0D-8K typeNational Standard LawCOD digestion reflux deviceThe digestion time can be set, and a countdown to the digestion time can be displayed. After digestion is complete, the instrument automatically stops heating, and the dual fans of the instrument continue to work, which can assist in sample cooling without supervision.

KHC0D-8K typeNational Standard LawCOD digestion reflux device，Using glass burr reflux tubes instead of spherical reflux tubes, and replacing circulating water cooling methods with air and water cooling technologies, the operation is more convenient. The cooling part is mainly completed by burr condensation tube water cooling and fan air cooling, and the upper part of the condensation tube is spherical3Bubble, good cooling effect, catalyst added from here, prevents the instantaneous volatilization of light components in the sample, and can be covered with a volatilization cap. The following section is"burr"Shape, protruding from the wall of a condenser tube on a plane3A person facing each other"Cold Bubble"Compared to a simple spherical condenser tube, it increases the cooling area and can block the passage of volatile substances and vapors. In addition, the cooling water in the upper part of the spherical reflux tube and the fan inside the machine have a dual effect,KHC0D-8K typeNational Standard LawCOD digestion reflux device，Ensure the reflux cooling of the sample，Insert type burr reflux tube, safe and stable to use.
