Iodine Tincture Extra Pure

Original price was: $ 19.00.Current price is: $ 18.54.
Iodine Tincture Extra Pure is a high-quality antiseptic solution composed of elemental iodine dissolved in a mixture of alcohol and potassium iodide. It is widely used for disinfecting wounds, sterilizing skin before medical procedures, and as a laboratory reagent in various analytical and microbiological applications. Its fast-acting antimicrobial properties make it effective against bacteria, viruses, and fungi. In laboratory settings, it serves as a reliable indicator and staining agent. Due to its volatility and staining nature, the tincture should be handled with care and stored in tightly closed, amber-colored bottles to preserve stability and prevent degradation.  

Lead Acetate Extra Pure

Original price was: $ 18.00.Current price is: $ 17.76.
Lead Acetate Extra Pure is a crystalline compound with the chemical formula Pb(C₂H₃O₂)₂·3H₂O, often referred to as sugar of lead due to its sweet taste (though it is highly toxic). In laboratory environments, it is primarily used for analytical chemistry, precipitation reactions, and as a reagent for detecting hydrogen sulfide gas, with which it forms black lead sulfide. It is also utilized in organic synthesis and historical pigment studies. Due to its toxicity, handling requires strict safety measures, including gloves, goggles, and proper ventilation. Its extra pure grade ensures minimal contaminants, making it suitable for precise experimental procedures.

Marble Chips Extra Pure

Original price was: $ 17.00.Current price is: $ 16.98.
Marble Chips Extra Pure are high-grade, naturally occurring calcium carbonate fragments that have been carefully processed to ensure exceptional purity. These white or off-white chips are widely used in laboratory experiments, especially in demonstrations involving acid-carbonate reactions where the release of carbon dioxide is observed. Beyond educational and research use, they also serve as a buffering agent, filtration medium, and mild abrasive in various industrial applications. Due to their chemical stability and high calcium content, marble chips are ideal for use in controlled environments where contaminants must be minimized.

Tartrazine yellow Extra Pure

Original price was: $ 17.00.Current price is: $ 16.70.
Tartrazine Yellow Extra Pure is a high-purity, water-soluble synthetic azo dye used extensively in laboratory, pharmaceutical, and regulated food and cosmetic applications. It provides a vivid yellow color with a characteristic absorption around 427 nm, making it ideal for use in analytical procedures such as spectrophotometry and dye behavior research. Its Extra Pure grade ensures low impurity content and consistent performance for research and testing. Due to its sensitization potential and ecological persistence, controlled handling and proper disposal are advised.

Zinc Phosphate Extra Pure

Original price was: $ 19.00.Current price is: $ 18.98.
Zinc Phosphate Extra Pure is a white, fine, odorless powder composed of trizinc diphosphate with high chemical stability and purity suitable for analytical and material science applications. It is widely used in laboratories for phosphate-based reactions, corrosion inhibition research, and dental material development. Known for its minimal solubility in water and compatibility with dilute acids, it serves as a stable phosphate source in various experiments. It is especially valued in lab-scale surface treatment simulations, pigment formulation testing, and environmental remediation trials. Zinc Phosphate’s inertness under standard conditions and non-toxic classification make it a preferred choice for controlled reactivity studies, inorganic synthesis, and coatings R&D. Proper handling is required due to its dusty nature, although it is considered non-hazardous under most regulatory frameworks.
