    Product Overview

    Powder form for neutralization and treatment.

    Detailed Description

    Sodium Thiosulfate Powder supplier in Oman - Global Chemicals LLC provides crystalline sodium thiosulfate for dechlorination, neutralization, and analytical applications in Muscat, Sohar, Duqm, Salalah. Our sodium thiosulfate pentahydrate powder (Na2S2O3·5H2O) offers convenient storage, precise measurement, and long shelf life for neutralizing chlorine and oxidizing biocides. Essential for oilfield operations requiring chlorine removal from produced water, well treatment chemical neutralization, and laboratory analysis. The powder form provides economical handling for large-scale applications and field operations. Dissolves rapidly in water to create neutralizing solutions on demand. Widely used by oilfield service companies, water treatment operations, and analytical laboratories across Oman. Sodium thiosulphate (Na₂S₂O₃·5H₂O) has several important applications in Oman's oil & gas and industrial sectors. In oilfield water analysis, sodium thiosulphate is used to quench residual chlorine/biocide in produced water samples before microbiological analysis — ensuring that the sample is representative and that biocide carryover does not suppress bacterial counts (leading to false negatives for SRB and APB testing). In Oman's water treatment sector, sodium thiosulphate is used for dechlorination of treated water before discharge to the environment. In photography (now mainly archival and industrial applications), sodium thiosulphate is the classic fixing agent. Global Chemicals LLC supplies sodium thiosulphate in technical and analytical grades in 25kg bags and 50kg bags for oilfield, water treatment, and analytical laboratory applications.
