Small size reagent bottles are essential laboratory containers designed for storing and dispensing small quantities of liquids, chemicals, or reagents. These bottles are commonly used in scientific research, pharmaceutical labs, and industrial applications where precise measurement and contamination-free handling are critical. They are typically made from materials like glass (borosilicate) or durable plastics (PP, PET, or HDPE) to ensure chemical resistance and longevity. Features may include leak-proof caps, graduated markings, UV protection, or sterilizability. Common variants include dropper bottles, screw-thread vials, and amber bottles for light-sensitive substances. Products in this category range from 5ml to 100ml capacities, often with specialized designs for solvents, acids, or biological samples.
