3.industrial grade/photo grade

1.Characters:                                                                             

Sodium thiosulfate, also known as thiosulfate, which is monoclinic white crystalline powder, specific gravity 1.667, soluble in water, insoluble in alcohol, is heated in air decomposed into sodium oxide and sulfur dioxide. Burned in pure oxygen is generated sodium sulfate, sodium sulfide and sulfur.

Storage                                                                                  

Should be stored in a cool and dry warehouse. Dark, sealed, transport should avoid exposure, humidity, rain. Not with acid and oxidant were mixed reservoir operation. Containers must be sealed to prevent moisture melt. Such as packaging moisture, indicating the contents from the deliquescence effect has to be packaged separately stacked and drying. Can not be stored in the open air, on the wet packing to grasp handle. Sand when fire fighting water.
