Food Colouring Blue Manufacturer,Supplier and Exporter in India

Food Colouring Blue (Product Code: SLE/CH/201) is a blue colouring liquid used in science lessons to make the movement of water and other clear liquids visible. Despite its name it is not for food use and is intended for educational purposes only. Teachers use it for convection, capillary and mixing demonstrations, and it is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a chemistry consumables supplier in India.

Specifications

Typical Use

A single drop of blue colouring placed at the bottom corner of a beaker of water, gently heated from below, traces a clear loop as warm water rises and cooler water sinks, which makes convection easy for a whole class to see. The same tinted water drawn up narrow glass tubes of different bores shows capillary rise, and a strip of paper towel dipped into blue water shows liquid creeping upwards through fibres. Blue is also a strong contrast colour against white paper and clear glassware, so readings of liquid levels in tubes and cylinders are easier to take.

Use it diluted: a few drops colour a full beaker, so a 500ml pack lasts across many practical sessions. Keep the bottle clearly labelled as not for food use, store it away from the kitchen or canteen, and wear an apron, since concentrated colouring can stain skin, benches and clothing. Paired with physics lab equipment in India such as convection apparatus, it turns an abstract idea into a visible flow pattern.
