Litmus Paper Blue is a pH indicator paper used to detect acidic substances. It is impregnated with litmus dye extracted from lichens, which changes color when exposed to acidic or basic environments. Blue litmus paper turns red under acidic conditions (pH < 4.5) and remains blue in neutral or alkaline solutions. It is widely used in laboratories, education, environmental testing, and industrial processes for quick and easy pH testing.

measuring cylinder glass
The Measuring Cylinder Glass is a fundamental laboratory apparatus specifically engineered for the precise measurement of liquid volumes. Constructed from high-quality, chemically resistant borosilicate glass, it ensures durability, resistance to chemical corrosion, and clarity for optimal visibility of liquid levels. The cylindrical shape provides a stable base and ergonomic design for ease of handling and pouring. Graduated volume markings, typically etched or printed with high contrast, allow accurate reading of liquid quantities down to the milliliter, supporting quantitative experiments and solution preparations. The transparent nature of the glass facilitates observation of the meniscus, which is critical for accuracy in volume measurement. Measuring cylinders vary in size, commonly ranging from small (10 mL) to large capacities (1000 mL or more), meeting diverse laboratory needs. They are widely used across chemical, biological, medical, educational, and industrial laboratories for tasks including volumetric analysis, solution preparation, and quality control. Their ability to withstand thermal fluctuations and autoclaving processes also makes them suitable for sterilized environments. Measuring Cylinder Glass is essential for maintaining precision and reproducibility in experimental and routine laboratory procedures.
