Glass Beaker is common lab equipment mainly used to mix some liquids and heat the liquids, containing, dissolving, boiling, and melting. This mainly applied to most kinds of labs, chemical engineering, the classroom, teaching experiment, quality testing, craft, and even home kitchens.SpecificationCapacity: 50mlMinimum Scale Value: 10mlMaterial: 3.3 Borosilicate GlassMax Temperature: 400 Celsius DegreeOverall Size: 45 x 60mm / 1.77 x 2.36 inch(D*H)Package Contents: 12 x Glass BeakersAdvantagesMade from 3.3 borosilicate glass, known for its exceptional durability and resistance. This material is heat-resistant, chemically resistant, and has excellent transparency, ensuring reliable performance in various laboratory settings.Feature a graduated printed scale, allowing for precise measurement and accurate volume readings. The smooth surface of the beaker provides easy cleaning and ensures clear visibility during experiments.InstructionsTo use our glass beakers, simply pour your liquid or substance into the beaker and utilize the graduated scale to measure the desired volume accurately.Noticea. When heating the beaker, place a mesh under it to heat it evenly. b. When it is used for dissolving, the amount of liquid should not exceed 1/3 of the volume of the beaker. When stirring, do not touch the bottom or walls of the cup. c. When the liquid is heated, do not exceed 2/3 of the volume of the beaker. d. When heating corrosive chemicals, a watch glass should be covered on the mouth of the beaker to avoid liquid splashing
