The GNST-12HLX COD reflux digester uses a glass burr reflux tube instead of a spherical reflux tube and air cooling technology instead of tap water cooling. The cooling part is mainly completed by a burr condenser tube and a fan. The upper part of the condenser tube is spherical, and the catalyst is added from here to prevent the instantaneous evaporation of light components in the sample. The lower part is "burr" shaped, with three opposing spherical condenser tubes extending from the condenser tube wall on a plane. In addition, the dual effect of cooling water and fan in the upper spherical reflux tube ensures the reflux cooling of the sample.
