Lugols Iodine Extra Pure

Lugol’s Iodine Extra Pure is a superior-grade aqueous solution composed of elemental iodine and potassium iodide, known for its wide-ranging applications in laboratories, microscopy, and medical diagnostics. Valued for its strong staining properties, it is commonly used in biology to identify starch in plant cells and as a general-purpose cellular stain to enhance visibility under a microscope. Its extra pure formulation ensures high clarity, minimal impurities, and consistent results in sensitive applications. Additionally, it plays a role in preparing specimens, sterilization procedures, and certain medical antiseptic practices. Store tightly sealed, away from light and heat, to preserve potency.

Pepsin Extra Pure

SHORT DESCRIPTION Pepsin Extra Pure is a highly refined proteolytic enzyme derived from porcine gastric mucosa, widely recognized for its ability to break down proteins into peptides. Appearing as a white to off-white, amorphous powder, it retains strong enzymatic activity and is soluble in dilute acids, making it ideal for biological and analytical applications. This Extra Pure grade is extensively used in biochemical research, pharmaceutical formulations, digestive studies, and food processing, particularly in the production of protein hydrolysates. It plays a crucial role in simulating gastric digestion in lab experiments and is also employed in diagnostic preparations and enzyme assays. Pepsin should be stored in a tightly sealed container under refrigerated conditions to maintain its activity, and care should be taken to avoid exposure to moisture and alkaline conditions, which can denature the enzyme.

Phenol Red Extra Pure

SHORT DESCRIPTION Phenol Red Extra Pure is a highly refined pH indicator dye widely used in biological and chemical laboratories. Appearing as a reddish crystalline powder, it changes color based on pH—yellow in acidic environments (pH < 6.8), red in neutral to slightly basic conditions (around pH 7.4), and fuchsia in more alkaline solutions (pH > 8.2). This Extra Pure grade is particularly suited for cell culture media, where it helps monitor pH fluctuations during cell growth and metabolic activity. It is also employed in analytical chemistry, water quality testing, and titrations. Phenol Red is stable under normal storage conditions but should be kept in a dry, tightly sealed container away from strong acids or bases. Proper lab safety protocols—such as wearing gloves and goggles—are recommended when handling the powder or concentrated solutions.
