GSC International 412-2 25ml Specific (Density) Gravity BottleThis 25ml capacity specific gravity bottle (also known as a density bottle) is used to measure the density of a liquid. It is used by measuring the difference between an empty bottle and a filled bottle and then dividing by an equal volume of water to find the specific gravity of the substance. The bottle is uncalibrated and has a ground glass stopper.Ground Glass Stopper with Capillary Bore: Prevents air entrapment and allows excess liquid to escape, ensuring exact volume control.Borosilicate Glass Construction: Chemically resistant and durable, suitable for repeated use in labs or classrooms.Ideal for Density Experiments: Used to determine the relative density of liquids or powdered solids in chemistry and physics labs.Compact and Educational: Small size is perfect for student experiments and demonstrations of core scientific principles.PRODUCT WARNINGSThis product is NOT A TOY. It is designed for educational, scientific, or professional use only. Adult supervision is required at all times. Improper use may cause injury or damage.
