Lab Expo Dean-Stark Water Content Tester uses heat distillation with a 500 mL flask to determine water content in suitable samples at temperatures up to 300°C.

Two testing assemblies enable parallel runs, while the external water-circulation system cools the condenser for vapor collection. Tool-free disassembly supports convenient tube removal during maintenance.

Manufactured for petroleum analysis, chemical research, and laboratory testing, this Dean-Stark distillation apparatus supports water separation and measurement.
