Product Name: 250ml Amber Reagent Bottle Model NO.: rongtai RG250 Capacity: 250ml Bottle Top: Stopper Material: Glass Disposable: Non-Disposable Trademark: RonGTAI Transport Package: Safety Box Packing Specification: 250ML Origin: Jiangsu HS Code: 7017200000 Product Description Name:Reagent Bottlesize:250mlBorosilicate 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 CLow form, with spout, with printed graduations for 50-1000ml
