Overview

The HCA-100 standard COD digester adopts microcomputer technology and reasonable design, which can simultaneously perform heating reflux digestion on 8 250ML conical bottles. According to the new national standard HJ 828-2017, the microcrystalline glass countertop uses high-quality electric furnace wires and a reasonable heating power to ensure a slight boiling for 2 hours.

Product Details

HCA--100Type standardCODThe digester is heated by a specially designed electric heating plate, with a microcrystalline glass tabletop and an overall structure,Reasonable isolation design, the microcrystalline heating plate is a single piece, and the installation and replacement of the electric furnace plate are very convenient and simple，When 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.

HCA--100Type standardCODThe digestion device can set the digestion time and display a countdown to the digestion time. After digestion is complete, the instrument automatically stops heating and the dual fans continue to work. It can assist in sample cooling and is unattended.

HCA--100Type standardCODDissolver, using glass burr reflux tube instead of spherical reflux tube, and air-cooled and water-cooledTechnology replaces circulating water cooling methods, making operation 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 to ensure cooling effect, catalyst is added from here to prevent the instantaneous volatilization of light components in the sample, and a volatilization cap can be added. 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,standardCODDigestion device,Ensure the reflux cooling of the sample,Insert type burr reflux tube, safe and stable to use.
