2. Application
| Industrial Uses |
Water Treatment |
Eliminating dissolved oxygen in waste water and in pipes;
Cleaning water pipes and reverse osmosis membranes in desalinization equipment as it is an antibacterial.
It is used in water treatment plants to remove excess chlorine. |
| Bleaching Agent |
It functions as a bleaching agent, which is useful in making paper pulp, cotton and wool. |
| Food Preservative |
| Antimicrobial |
It is commonly used as a food preservative for dried foods, as well as fruit concentrate juices.
It acts as an antimicrobial, inhibiting the growth of fungi and bacteria, thereby keeping food fresh and safe. |
| In beer and wine manufacturing, it is used as both a sterilizer and an antioxidant in the process of brewing beer or fermenting wine. |
| Other Uses |
|
| Medicinal |
It is an antioxidant additive in inject able medicines and is also used as a reducing agent in pharmaceuticals. |
| Photographic and film industry |
For preparing developer solutions, for acidifying fixing baths(photo grade). |
| Landscape Gardening |
It used in landscape gardening as a tree stump remover, as it disintegrates the lignin -- chemicals in plant cell walls -- in the tree stumps, making them easier to remove. |
| Fiber Industry |
In the sulphitisation of tanning extract. |
| Gold mining |
For bleaching ground wood, as an antichlor. |

1.The Advantage of ChoiceChem Sodium Metabisulphite
(1).High Purity
Our sodium metabisulfite is of higher purity than our competitors. If you use our sodium metabisulfite you will use less, lowering your cost.
In gold ming water treatment, regular sodium metabisulfite with a purity of 95% needs a dosage of 6.12g/L. Ours is of a higher purity (usually >97.5%) which needs a lower dosage of 6g/L.
(2). Suitable Packaging
a. ChoiceChem can supply different size jumbo bags (500KG, 1000KG, 1100KG, 1200KG, 1250KG, 1300KG, 1350KG) to suit every need.
b. ChoiceChem can provide UV-proof packaging and anti-freeze packaging. In extremely hot and cold climates the packaging will still be intact and in perfect condition.
(3). No Caking
ChoiceChem sodium metabisulfite doesn't cake or stick together. This takes away additional time, labour and cost to crush the product.
a. ChoiceChem uses a next day stacking system. The packaged sodium metabisulfite is stored overnight with a gap of 10cm between each row of product to allow ventilation and cooling. The next day the sodium metabisulfite is stacked before it is grouped. It is then moved to the official cargo space. Due to the loading and unloading process the water between the sodium metabisulfite is destroyed. As the temperature of the sodium metabisulfite has dropped it will not decompose again. This stops a secondary grouping after re-stacking.
Our anti-caking method is very effective in maintaining the quality of sodium metabisulfite.
b. ChoiceChem packs moisture absorbers throughout the shipping containers. This stops any moisture or water being absorbed by the sodium metabisulfite during shipping.
As the biggest sodium metabisulfite producer in Southern China, we hope we can work with you!

1. How Do You Control Your Quality?
ChoiceChem maintain good quality control by following these procedures below:
(1) ChoiceChem Only Uses High-Purity Raw Material
A. By using 99.8% pure imported S, the high-purity S allows for the generation of very high-purity SO2. This is further used to create a much better high-purity Sodium Metabisulphite than what is usually available in the market.
Please note that ChoiceChem's Sodium Metabisulphite's purity is commonly measured above 98%, which is substantially higher than the regular Chinese national standard of 96%.
B. ChoiceChem uses a high-purity Soda Ash which has an alkali content of more than 99.2% and NaCl content of less than 0.97%.
This way, our high-purity Soda Ash helps us to produce higher purity Sodium Metabisulphite, and can also avoid impurities like Cl and Iron, which allows our products to better meet pulp industrial requirements.
(2) Strict Factory Inspection System
All our products are tested every 2 hours, and sub-standard products are allowed to leave the factory.
We also carry out third-party tests every 3 days to ensure that our in-house tests are properly calibrated and accurate.
(3). Strict Package and Loading System
ChoiceChem only uses high-quality packages, and we always pack the cargo after it has cooled off totally to avoid expansion caused by SO2.
The cargo can be loaded directly in our factory, whole the loading process can be inspected by our in-house supervisors.
2. What Is Your Delivery Time?
(1) ChoiceChem delivery time is regularly updated according to the level of orders every day.
(2) Choicechem's current output is 300MT daily. This allows most cargo orders to be delivered within 7 to 10 days usually.
If it is China, where Entry-Exit Inspection and Quarantine (CIQ) inspection of cargo is needed, an extra 1 week will be required for applying and accepting CIQ inspection.
If you need an OEM package, colorful package, or need to engrave (for printing), we will need around 5 to 7 days for this.
Also, printing bags need around 1 to 3 days, and domestic transportation will require around 3 to 5 days, so an extra 2 weeks will be needed.
For the black color marks package and to engrave (for printing), we will need around 1 to 2 days for this. Printing bags need around 1 to 3 days, and domestic transportation for this will also require around 3 to 5 days, so an extra 7 to 10 days will be needed;
