Sodium Tetraborate (Borax)
Sodium Tetraborate (Borax) (Product Code: SCL382/091) is a boron salt used as a primary standard in acid titrations, for the borax bead test, as a buffer and in crystal and polymer activities in school and college laboratories. It is supplied in a 200 g pack of analytical reagent grade with an MSDS, a practical quantity for volumetric analysis classes. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Borax Used For?
In volumetric analysis, a carefully weighed amount of borax dissolved in water is titrated against hydrochloric acid with methyl orange or methyl red to find the exact strength of the acid, which is why borax appears in almost every volumetric analysis kit. In qualitative inorganic analysis, a wire loop dipped in borax and heated forms a clear, glassy bead. Touching the hot bead to a trace of a metal salt and reheating gives characteristic colours, such as blue for cobalt and green for chromium.
Teachers also use borax solution to cross-link polyvinyl alcohol into a stretchy polymer ‘slime’ when teaching polymers, and to grow crystals on pipe-cleaner shapes. Borax is harmful if swallowed, so avoid raising dust, keep it away from young children and food areas, wash hands after use and follow the supplied MSDS.
Supplier
Sodium Tetraborate (Borax) is sourced by Jain Scientific Equipments Private Limited, the company behind the ScienceLab brand in Ambala, Haryana, and supplied with its MSDS.

Frequently Asked Questions
What is Sodium Tetraborate (Borax) used for?
Sodium Tetraborate (Borax), code SCL382/091, is used as a primary standard for standardising acids, in the borax bead test for metal ions, as a buffer, and in crystal-growing and polymer activities in school and college labs.
Why is borax used as a primary standard?
Sodium Tetraborate (Borax) is a crystalline solid that, when stored properly, can be weighed accurately and reacts completely with strong acids. A known mass therefore gives a reliable reference for finding the exact concentration of hydrochloric acid in titration practicals.
What pack size is Sodium Tetraborate (Borax) supplied in?
Sodium Tetraborate (Borax) is supplied in a 200 g pack of analytical reagent grade with an MSDS. Tell us the number of packs you need for titration, bead-test or polymer sessions and we will quote accordingly.
How should Sodium Tetraborate (Borax) be stored?
Keep Sodium Tetraborate (Borax) in a tightly closed container in a cool, dry cupboard, because its crystals can gain or lose water when exposed to air, which affects accurate weighing. Label it clearly and keep it away from food and young children.
Does Sodium Tetraborate (Borax) have an expiry date?
The shelf life of Sodium Tetraborate (Borax) depends on the chemical, its grade and storage conditions, so we do not quote a standard period. Ask us for the expiry date of the batch you are quoted before stocking up for the session.
Who supplies Sodium Tetraborate (Borax)?
Sodium Tetraborate (Borax) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources this reagent and supplies it with titration glassware to schools, colleges, dealers and importers in India and international markets.
