Evaporation Residue Tester
Evaporation Residue Tester
Product Code : ERT-01
Brand Name : Labthink
Product Description

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.

  • Proportional, standard and differential value modes are available for different test requirements of users
  • 8 specimen tests could be performed simultaneously with automatic testing process, which greatly improves determination efficiency.
  • Test process can be simplified by automatic conduction of control test
  • Automatic lifting structure design and periodically weighing method to reduce system errors
  • Auto re-zero before each weighing ensures the accuracy of test results
