300ML/500ML High-purity Hydrogen Generator Laboratory Hydrogen

300ML/500ML High-purity Hydrogen Generator Laboratory Hydrogen Production Machine N ew　

Attention: 1. The machine needs to prepare electrolyte by yourself: Dilute 100 grams of analytically pure potassium hydroxide (KOH) with 400-500ml  of distilled water. After dissolving, inject it into the liquid tank of the  machine, and then replenish the distilled water to the "H" mark (do not exceed). 2. Each time the electrolyte is prepared, it can be continuously replenished  with purified water or distilled water, which can be used for about 2-6 months.  When you do not use this machine for a long time, you need to drain the  electrolyte.

Description: It is easy to operate and only needs to be turned on to generate hydrogen.  The output pressure is stable, the digital display is eye-catching and  intuitive. Made of PC polycarbonate pipe, pressure resistance, reagent  resistance, impact resistance, and not easy to break.
