Glass Pipettes

Glass pipettes are precision instruments used in laboratories for measuring and transferring specific volumes of liquids. They are typically made from borosilicate glass, ensuring durability and resistance to thermal shock and chemical corrosion. Pipettes come in various types, including volumetric, graduated, and Pasteur pipettes, each serving distinct purposes. Volumetric pipettes are designed to deliver a single, precise volume and are often used in quantitative analysis. Graduated pipettes have markings along their length, allowing for the measurement of varying volumes. Pasteur pipettes, also known as droppers, are used for transferring small amounts of liquids. The design usually features a slender, cylindrical tube with a tapered tip to facilitate accurate dispensing. Some pipettes come with cotton plugs to prevent contamination. Proper calibration and handling are essential to maintain accuracy. They are commonly used in chemistry, biology, and medical laboratories for tasks such as titrations, sample preparation, and reagent addition. Cleaning and sterilization are crucial to prevent cross-contamination and ensure reliable results.
