HCA-102Standard Type COD Dissolver with Computerized Technology, designed rationally, capable of simultaneously heating and refluxing digestion for 8 250ml conical flasks.Completely in accordance with the new national standard HJ 828-2017 National Standard MethodMicrocrystalline glass countertop, using electric wire, with a reasonable heating power to ensure gentle boiling for 2 hours.
HCA--102Type Standard COD Dissolver is equipped with a special electric heating plate for heating, featuring a microcrystal glass top surface and an integrated structure.Reasonable air gap design; the microcrystalline heating plate is a single piece, making it very easy and simple to install or replace the electric stove plate.，The electric furnace plate heats evenly during operation, with rapid heating and cooling. Accidental spills of the sample solution are easy to clean up.
HCA--102Standard COD Dissolver with adjustable dissolution time, countdown timer for dissolution time, the instrument automatically stops heating upon completion, dual fans continue to operate to assist sample cooling, unattended operation.
HCA--102Standard Type COD Dissolver with glass wool hair reflux tube replacing spherical reflux tube, and air-cooled with water-coolingTechnology replaces the recirculating water cooling method, making operation more convenient. The cooling section is mainly completed by water cooling of burr condenser pipes and fan air cooling, with the upper part of the condenser tube being spherical.3Bubble to ensure cooling effect; catalyst is added here, preventing the instantaneous volatilization of light components in the sample, and a volatile cap can be sealed on top. The lower part is"Burrs"Shape, extending from the condenser tube wall on a plane3Opposite direction"Iced Brew"The cooling surface area is significantly increased compared to a simple spherical condenser tube, and it can also block the passage of volatile substances and vapors. Additionally, the combined effect of the cooling water inside the upper spherical reflux tube and the internal fan of the machine enhances this function.Standard COD Dissolution ApparatusEnsured the sample's回流cooling.Insert the tangling burr reflux tube; it operates safely and stably.
