ERT-01 Evaporation Residue Constant Weight Tester is professionally designed for the precisely quantitative determination of dissolved substances of table wares, containers, packaging films, cans, tubes and other food-use equipments in different soaking solutions. Polyethylene (PE), polystyrene (PS), polypropylene (PP), and chlorinated PVC resin are used as raw materials of such objects. By the further detection of evaporation residues, more dissolution indexes could be obtained to meet different application requirements of products. The instrument also supports LystemTM Lab Data Sharing System, which ensures uniform management of test results and test reports.
ERT-01 utilizes Labthink’s latest embedded computer control system that provides better performance than traditional single chip system.
The instrument is equipped with Labthink’s latest intelligent operating software, with user-friendly operating interface and intelligent data management. It also supports LystemTM Lab Data Sharing System, which ensures uniform management of test results and test reports.
Soak the specimen into solution according to related requirements. Take out certain quantity of soaking solution and inject into conditioned evaporating dish which has been dried in high temperature oven and comes with constant weight. Dry the evaporating dish with soaking solution on water bath, prior to placing it into high temperature oven for further drying and weighing. Continue the dry and weigh operation until the weight of evaporating dish reaches constant. The quantity of evaporation residues could be obtained by reducing mass of empty dish from the final constant dish mass.
This instrument conforms to many national standards:
GBT 5009.60-2003, GB/T 5009.64-2003, GB/T 5009.68-2003, GB/T 5009.69-2008, GB/T 5009.203-2003, and GB/T 9740-2008
