Fisherbrand Serialized Graduated Cylinder 2000 ml 20 ml Graduations

Fisherbrand Serialized Class A Graduated Cylinder, 2000 mL Capacity with 20 mL Subdivisions (08-559H)

The Fisherbrand Serialized Class A Graduated Cylinder (08-559H) is a high-precision volumetric measuring instrument engineered for exact liquid measurement, volumetric analysis, and reagent preparation in analytical chemistry and pharmaceutical laboratories. Manufactured from low-expansion ASTM E438 Type I, Class A borosilicate glass, this 2000 mL cylinder delivers exceptional thermal stability and chemical resistance against aggressive acids, alkalis, and organic solvents. Built to conform with ASTM E1272 Class A specification standards, each individual cylinder is permanently marked with a unique serial number and calibrated "To Contain" (TC) at 20 degrees C. The cylinder features double-metric scale white enamel graduations in 20 mL increments for easy meniscus reading, supported by a heavy hexagonal base to prevent tipping and roll-away accidents.

Technical Performance & Structural Attributes

• ASTM E1272 Class A Volumetric Accuracy: Individually calibrated to meet strict Class A volumetric tolerances, ensuring high-accuracy volumetric measurements for certified laboratory testing.
• Individually Serialized & Certified: Features a permanently fired serial number on the glass body matching its factory certificate of volumetric traceability.
• Borosilicate Glass Type I, Class A: Premium borosilicate glass construction resists thermal shock, chemical etching, and stress cracking during aggressive wash cycles.
• Heavy Hexagonal Base Geometry: Wide, low-center-of-gravity hex base provides superior mechanical stability and prevents accidental tipping on laboratory benchtops.
• Durable White Enamel Scale Markings: High-contrast, permanently fused white enamel lines and numerals remain legible after exposure to harsh cleaning solvents and repeated autoclaving.
