Measuring Cylinder 5ml

Product Name: Measuring Cylinder 5ml Model NO.: rongtai Capacity: All Size Material: Glass Certification: CE, ISO Trademark: Rongtai Transport Package: Standard and Disposable Export Package Specification: 25ml -2000ml Origin: Jiangsu, China HS Code: 7017200000 Product Description Measuring cylinderBoro 3.3, graduated, size from 25ml to 2000ml.Borosilicate Glass entirely conforms to the international standard ISO3583, and is a new special borosilicate glass of excellent chemical and physical properties with a silica content of 80%. It is highly stable in structure and, as a result, has marked mechanical strength and very high resistance against chemical attacks. Further, due to its low linear coefficient of thermal expansion, this glass is capable of withstanding high thermal shock and possesses good moulding ability. It is an excellent material for making laboratory apparatus where external heating is necessary, intricate laboratory glassware and chemical equipments as well as pressure water meter glass.Principal Physical and Chemical Properties:SiO2 Content...>80%Strain Point...520º CAnnealing Point...560º CSoftening Point...820º CRefractive Index...1.47Light Transmission (2mm)...92%Elastic Modulus...67KNmm-2Tensile Strength...40-120Nmm-2Glass Stress Optical Coefficient...3.8*10-6mm2/NProcessing Temperature(104dpas)...1220º CLinear Coefficient of Expansion(20-300º C)...3.3*10-6K-1Density(20º C)...2.23gcm-1Specific Heat...0.9Jg-1K-1Thermal Conductivity...1.2Wm-1K-1Hydrolytic Resistance (ISO 719)...Grade 1Acid Resistance (ISO 195)...Grade 1Alkali Resistance (ISO 695)...Grade 2Thermal Shock Resistance Rod...6*30mm 300º
