Product Description RONGTAI Laboratory Glassware Suppliers Transparent Clear Glass Volumetric Flask China Chemical Glass Volumetric Measuring FlaskProduct IntroductionA Volumetric Flask, Also Known As A Graduated Flask Or A Volumetric Flask, Is A Thin-Necked, Pear-Shaped, Flat-Bottomed Volumetric Vessel With A Ground Glass Stopper And A Marking Line On The Neck, Indicating That The Concave Liquid Level Of The Liquid Is At The Indicated Temperature. When The Marked Line On The Neck Of The Volumetric Flask Is Tangent, The Volume Of The Solution Is Exactly Equal To The Volume Marked On The Flask. The Volumetric Flask Is Marked With Temperature, Capacity, and Scale Marks. It Is A Precise Instrument For Preparing A Solution With An Accurate Concentration Of A Certain Substance.Volumetric Flasks Are Usually Clear, But Some Dosing Flasks Used To Handle Light-Sensitive Compounds Such As Silver Nitrate And Vitamin A May Be Brown. Features-Automatic Measurement, Eliminate Human Factors, Ensure Product Accuracy-High Borosilicate BORO3.3 Glass Material-Excellent Chemical And Heat Resistance-Laser Engraved Lines, Uniform Lines, Non-Printed Scale Lines, Acid And Alkali Resistant-High-Temperature Resistance-High Strength, High Hardness-High Transmittance-High Chemical Stability-Low Expansion Ratio-Uniform Wall Thickness Distribution Suited To Heat-Clear Mark For Easy IdentificationClasses Of A Volumetric Flask There Are Two Classes In Which A Volumetric Flask Is Manufactured - Class A And Class B. The Class A Volumetric Flasks Have The Highest Level Of Accuracy With Tighter Tolerance Limits. They Have A Unique Serial Number For Traceability. The Graduation Mark On The Flask Is Accurately Placed On The Flask.The Highest Accuracy Class A Volumetric Flasks Have A Blue Color Print For Clear Glass And White For Amber Variants.The Class A Flasks Are Individually Calibrated With Their Certification. Class A Borosilicate Volumetric Glassware Has Superior Thermal And Chemical Resistance And Is Better Suited To Glassware For Storage Of Solutions, E.G. Flasks. The Use Of Class A Borosilicate Glass For Volumetric Glassware Means Accuracy Is Retained Over A Longer Working Lifetime Than Their Soda-Lime Equivalents.The Class B Volumetric Flasks Are Used For General Purposes And Calibrated To A Lower Level Of Accuracy. The Flasks Under Class B Have White Print On Them. Class B Flasks Lack Calibration. These Volumetric Flasks Are Generally Used In Schools.Product Details-Fine Grinding-Thick Wall-Good Sealing-Frosted Cork-Novel And Simple Structure -Thick Wall-Beautiful, Elegant-Pear Shape-Flat Bottom-Easy to mix with a stir bar-Clear Markings Product ParametersProduct NameVolumetric FlaskKeywordsGlass Volumetric FlaskMaterialBorosilicate GlassApplicationChemical LaboratoryCapacity250ml/500ml/1000ml etcColorClearAmberCertificateCE ISOSampleOfferedModel Number1621A,1621BFeatureAcid Resistance And Heat ResistanceProduct TypeWith Ground In Glass StopperBottle BottomFlatDensity2.45Softening Point735LogoOEM Logo Acceptable Item codeCapacity(ml)Capacity tolerance(ml)Ground mouthHeight(mm)1621A-550.027/11741621A-10100.027/11901621A-25250.0310/131101621A-50500.0510/131401621A-1001000.112/141701621A-2002000.1514/152101621A-2502500.1514/152201621A-5005000.2516/162601621A-100010000.419/173101621A-200020000.624/20370 CodeCapacity(ml)O.
