Convenient Features

The electrolytic cell is equipped with an automatic liquid discharge port. By turning on the switch, the waste liquid can be discharged without the operator coming into contact with the reagent, so as to avoid the possibility of damaging the electrolytic cell due to manual liquid discharge under normal circumstances. In addition, it also avoids the external drainage system, which may cause a decrease in the sealing of the instrument and make it difficult to reduce the background.

Extended features

An automatic liquid extraction system can be configured, which is suitable for users analyzing liquid samples. It does not require the operator to manually remove the already reacted samples in the electrolytic cell, and also avoids the impact of chemical reagents on the human body.
