Product Description This glass bottle is suitable for small sample testing. Made of glass, it is corrosion-resistant and high-temperature resistant. It provides accurate measurements and is suitable for experiments such as density and specific gravity. It has good sealing properties to prevent liquid leakage. It is easy to use and suitable for daily laboratory use. Product Features - Color: As shown in the picture - Material: Glass - Dimensions: 4.00 x 2.90 x 2.90 cm / 1.57 x 1.14 x 1.14 inches - This is a device that can accurately measure the volume of glass or metal containers. - A specific gravity bottle with a known volume can be used to determine the density of powders, liquids, and particles. - Suitable for measuring liquid density and analyzing the purity, volatility, or content of substances in industrial, laboratory, school, and agricultural settings. - Made of glass, it has an extremely low coefficient of thermal expansion and is high-temperature resistant. - Before use, the thermometer, empty bottle weight, and water weight should be strictly calibrated according to requirements. It can only be used after calibration. Packing list: 1 x Laboratory Bottle
