Benedict’s Solution 250ml is a ready-to-use qualitative chemical indicator supplied by IBEX SCIENCES. Operating from their primary sales outlet in New Anarkali, Lahore, the company distributes this deep blue reagent in a practical 250ml fluid volume. It is highly sought after by school laboratories, diagnostic testing counters, and university biochemistry cells across Pakistan, bypassing the manual formulation steps required when blending raw copper sulfate and sodium citrate salts.
To check real-time batch availability, confirm current retail prices, or coordinate local pickup or courier dispatch, you can contact their Lahore desk directly.
Chemical Profile & Laboratory Applications
Benedict’s Solution features distinctive reactive properties widely utilized to detect specific biochemical compounds:
- Reducing Sugar Detection: It serves as the standard assay to check for the presence of reducing sugars (such as glucose, fructose, and maltose). When mixed with a sample and heated in a hot water bath, it reacts with the aldehyde or ketone groups of the sugar.
- Visual Color Transition: The solution transitions through a spectrum of colors depending on the concentration of reducing sugar present. It shifts from its original clear blue (negative) to green (trace), yellow (low), orange (moderate), and finally a brick-red precipitate (high concentration).
- Alkaline Composition: Formulated as a stable complex of copper(II) sulfate, sodium citrate, and sodium carbonate. The sodium carbonate provides the necessary alkaline environment, while the sodium citrate acts as a complexing agent to keep the cupric ions from precipitating out prematurely.
- Storage Requirements: The solution should be kept tightly sealed in its original bottle and stored at room temperature in a dry chemical locker. Avoid freezing temperatures or prolonged exposure to direct sunlight, which can compromise the indicator’s analytical sensitivity.
