GL-108National standard COD digesterDetailed introduction
Product Overview
GL-108 typeNational standard COD digesterFollowing the national standard (GB11914-89) and environmental standard (HJ828-2017), ensure the digestion operation with reflux heating and micro boiling for 2 hours, prepare and add the reagent solution according to the standard method *, and ensure reliable and accurate analysis results.
Product Features
1. Using imported microcrystalline panels, it can withstand high temperatures of 700 ℃, generate heat evenly, have fast rise/fall speeds, and have a smooth and easy to clean and maintain surface.
2. A new type of high-temperature resistant ceramic fiber heating plate with uniform thermal conductivity,
3. The glass burr reflux tube and heat dissipation system have good digestion reflux effect to ensure the parallelism and accuracy of the digestion results.
4. Digital display of microcrystalline panel temperature. Digital display of digestion time: temperature and timing can be set at any time.
5. After digestion is completed, the equipment automatically stops heating and the fan continues to work for 120 minutes to assist in sample cooling. It can be operated unattended.
