Solution Fehling B (Product Code: SCL376/088) is the colourless alkaline tartrate half of Fehling’s reagent, mixed with Fehling A to detect reducing sugars and aldehydes in school, college and food-science laboratories. It is supplied in a 250 ml bottle of analytical reagent grade with an MSDS, matching the bottle size of its partner solution. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, together with other school biology lab equipment.

Specifications

What Is Fehling Solution B Used For?

Fehling B conventionally contains potassium sodium tartrate (Rochelle salt) in sodium hydroxide solution. When it is mixed with the copper sulfate of Fehling A, the tartrate holds the copper in a soluble deep-blue complex instead of letting it fall out as copper hydroxide, and the alkali provides the conditions for a sugar to reduce it. Students can then compare glucose, fruit juice, honey, milk or a sucrose solution by watching which ones form a brick-red precipitate on heating.

Because it is strongly alkaline, Fehling B is corrosive to skin and eyes, so it should be dispensed by staff or under close supervision, with goggles and gloves. Alkaline solutions can make glass stoppers stick, so keep it in a bottle with a suitable plastic or rubber closure and store it upright in the chemistry reagent cabinet, away from acids.

Reactive Biureti (Product Code: SCL378/089) is a biuret reagent used to detect proteins and peptides through a blue-to-violet colour change in school biology, food-test and biochemistry practicals. It is listed as a 250 ml bottle of analytical reagent grade with an MSDS, sized for teachers running food tests with whole classes. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a biology lab equipment supplier in India.

Specifications

What Is Biuret Reagent Used For?

The biuret test is the standard classroom test for protein. Students add a few drops of the reagent to a sample such as egg white, milk or a soaked pulse extract; if protein is present, the blue solution turns violet or lilac within a few minutes, with no heating needed. Copper ions in the alkaline reagent bind to the peptide bonds that link amino acids, so the test responds to proteins and peptides rather than to single amino acids.

Run it alongside the iodine test for starch and Fehling’s or Benedict’s test for reducing sugars to complete a set of food tests. The reagent is alkaline and contains copper, so wear eye protection, wipe splashes promptly and collect used mixtures for disposal as described in the MSDS. Keep the bottle closed so the alkali does not absorb carbon dioxide from the air.

Potassium and Sodium Tartrates (Product Code: SCL380/090) is a tartrate salt reagent, the name normally referring to potassium sodium tartrate (Rochelle salt), used to prepare Fehling’s solution B and biuret reagent and for crystal-growing work in teaching laboratories. Technicians who make up their own reagents buy it as a 100 g pack of analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier.

Specifications

What Is Potassium Sodium Tartrate (Rochelle Salt) Used For?

Its main job in the teaching lab is reagent preparation. Dissolved with sodium hydroxide it forms Fehling’s solution B, and it is also an ingredient of many biuret reagent recipes; in both, the tartrate keeps copper ions in solution under alkaline conditions so the colour tests work. Keeping the dry salt lets a technician prepare fresh solution only when a practical is scheduled.

Rochelle salt also grows large, clear crystals from a warm saturated solution left to cool slowly, which makes it a popular choice for a crystallization kit in school science clubs. Physics teachers use the same crystals to introduce piezoelectricity, because they produce a small voltage when squeezed. The salt is of low hazard compared with many reagents, but avoid dust in the eyes, keep the pack sealed in a dry cupboard and follow the MSDS.

What to Specify When Ordering

• Confirm that you need potassium sodium tartrate (Rochelle salt), the double salt, rather than separate potassium and sodium tartrates.
• Number of 100 g packs required.
• Whether sodium hydroxide or copper sulfate should be quoted too, for making Fehling’s or biuret reagent.

Supplier

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.

Specifications

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. We can bundle it with burettes, flasks and indicators for a complete titration set-up. Company details are on our company profile page.

Potassium Iodine-Iodine Solution (Product Code: SCL384/092) is an iodine solution containing potassium iodide, used to test for starch and to stain plant and animal cells in biology and chemistry teaching laboratories. It is supplied in a 250 ml bottle of analytical reagent grade with an MSDS for schools stocking an iodine solution for lab food tests. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Iodine Solution Used For?

The starch test is its most common use: a few drops on a food sample or starch suspension change from yellow-brown to blue-black when starch is present. Students use the same colour change to follow the digestion of starch by amylase over time, and to show that a green leaf kept in light has made starch once its chlorophyll has been removed with warm alcohol.

Under the microscope, the solution works as a simple stain: it colours starch grains in potato cells blue-black and makes the nuclei of onion epidermis cells easier to see, so it is a staple of any staining kit for the biology lab. Iodine marks skin, clothing and benches and irritates the eyes, so dispense it from a dropper bottle and wear goggles. Store it tightly closed in a brown bottle away from light, which slowly weakens it.

Phenolphthalein Solution (Product Code: SCL386/093) is an acid–base indicator solution used to detect the end point of titrations and to show whether a solution is alkaline in school, college and university chemistry labs. It is supplied in a 100 ml bottle of analytical reagent grade with an MSDS, a convenient size for a titration kit in schools. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Phenolphthalein Solution Used For?

Phenolphthalein is colourless in acidic and neutral solutions and turns pink to magenta in alkaline ones. In a typical titration, two or three drops are added to the acid in a conical flask, and sodium hydroxide from a burette is run in until the first permanent faint pink appears – the end point. It suits titrations of strong or weak acids against strong bases, such as hydrochloric, acetic or oxalic acid with sodium hydroxide.

Outside titration, a drop on a freshly broken concrete surface shows how far carbonation has penetrated, and colour-change demonstrations use it to turn a clear liquid pink with a base. Indicator solutions of this kind are commonly prepared in alcohol, so keep the bottle away from flames, close it after use to limit evaporation and wear eye protection. Keep it with the other bottles of your acid base indicator kit.

Letter pH Indicator (Product Code: SCL390/095) is a paper pH indicator used to show whether a liquid is acidic, neutral or alkaline in school, college and teaching laboratories. Students and teachers use it for fast bench checks where a meter would be unnecessary, and its indicator range covers the full pH 0–14 scale. This pH indicator paper is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is pH Indicator Paper Used For?

A strip of the paper is touched to a drop of the test liquid, and the colour it develops is compared with a pH colour chart to read an approximate value anywhere between 0 and 14. Typical classroom uses include sorting household substances such as vinegar, soap solution and baking-soda water into acids and bases, following a neutralisation as alkali is added to acid, and checking water or soil extracts in environmental projects.

Unlike red and blue litmus, which only says acid or alkali, a 0–14 paper gives students a number to record, so it suits results tables and comparisons. For clean readings, apply the liquid with a glass rod instead of dipping strips into a stock bottle, read the colour straight away, handle the paper with dry hands or forceps, and keep the container closed and away from acid or ammonia fumes.

What to Specify When Ordering

• The quantity you need for your laboratory or class groups, and the pack format you prefer (ask us which formats are available).
• Confirmation that the full pH 0–14 range suits your experiments.
• Whether a pH colour chart, litmus paper or a pH meter should be added to the same quotation.
• Your delivery location in India or abroad, so dispatch can be included in the quote.
