Sodium Thiosulphate Supplier in Malaysia
- Also known as
- Sodium Thiosulfate
- Na2S2O3
- Photographic Hypo
Sodium thiosulphate supplier enquiries in Malaysia commonly cover water treatment dechlorination, photographic fixing, textile bleach neutralisation and laboratory titration. Also known as sodium thiosulfate, Na2S2O3 and photographic hypo, this inorganic thiosulphate salt is selected as a reducing agent and chlorine scavenger in industrial process work.
Commercial buyers choose between sodium thiosulphate pentahydrate crystals and anhydrous powder, and between technical and photographic grades. Pentahydrate crystals are the usual industrial form, while anhydrous material is specified when the process or written identity requires the water-free salt. Assay, hydration state and grade documentation should be stated with the enquiry.
Water treatment plants and process operators use technical grades for dechlorination and residual chlorine control. Textile processors use it to neutralise residual chlorine after bleaching. Mining and metal-extraction circuits may specify thiosulphate leaching reagents, while manufacturing and laboratory buyers select photographic or analytical grades for fixer baths and titration work.
Send the required form, grade, specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation, together with a stated price validity period.

Sodium Thiosulphate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Sodium thiosulphate pentahydrate crystals | white crystals or crystalline granules | — | General industrial and process use where the pentahydrate salt is specified, including dechlorination, photographic fixing and laboratory preparation. | Confirm the required pack format with the quotation. |
| Sodium thiosulphate anhydrous powder | white free-flowing powder or crystalline powder | — | Formulations and process systems that require the anhydrous salt or a specification written to Na2S2O3 without water of crystallisation. | Confirm the required pack format with the quotation. |
| Technical grade sodium thiosulphate | crystals or powder according to the quoted grade | — | Water treatment dechlorination, chlorine residual control, textile bleach neutralisation and general industrial reducing-agent work. | Confirm the required pack format with the quotation. |
| Photographic grade sodium thiosulphate | crystals or powder according to the quoted grade | — | Photographic fixer baths and related imaging chemistry where a photographic grade or low-impurity profile is required. | Confirm the required pack format with the quotation. |

Common questions about sodium thiosulphate
Are sodium thiosulphate and sodium thiosulfate the same product?
Yes. Sodium thiosulphate is the British spelling and sodium thiosulfate is the American spelling of the same salt, Na2S2O3. Buyers should still state pentahydrate or anhydrous, grade and the target specification because commercial lots differ by hydration state and impurity profile.
What is the difference between pentahydrate crystals and anhydrous powder?
Pentahydrate sodium thiosulphate contains water of crystallisation and is the form most often supplied as crystals for industrial and photographic use. Anhydrous material is the water-free salt and is chosen when a process or specification is written to Na2S2O3 without hydrate water. Do not treat the two forms as interchangeable without checking the required identity.
Is sodium thiosulphate the same as photographic hypo?
Photographic hypo is a traditional trade name for sodium thiosulphate used in fixer baths. Bare "hypo" is ambiguous and can be confused with other chemicals, so enquiries should use the full product name and the required grade. Photographic grade material is selected when imaging chemistry needs a tighter impurity or appearance profile.
Which grade should I request for dechlorination or water treatment?
Technical grade sodium thiosulphate is commonly requested for dechlorination and chlorine residual control. State the residual chlorine duty, dosing method, required form and any assay or documentation limits so the quoted grade can be matched to the process.
What specifications should a sodium thiosulphate enquiry include?
State pentahydrate or anhydrous, required assay, intended application, quantity and delivery location. For photographic or laboratory work, note any purity, appearance or documentation limits. For water treatment or textile use, describe the dechlorination or bleach-neutralisation duty.
How is sodium thiosulphate priced and packed?
Price depends on form, grade, specification, quantity, packing and delivery requirement. List preferred pack format and any documents your quality system needs with the enquiry. Packing, documentation and commercial terms are confirmed with the quotation and a stated validity period.
