Standard Specification for Laboratory Glass Graduated Cylinders
2024年11月15日 · This specification covers the requirements for laboratory glass graduated cylinders for precision and general purpose grades. The graduated cylinders may be in one of three styles; beaded lip with spout, grounded standard taper neck, or beaded lip with pour spout and reinforcing band near the top.
2019年5月20日 · This Handbook classifies volumetric flasks with graduated necks and graduated cylinders (see Fig. 1 through 4) for legal metrology applications as "field standards."
4.1 Style I cylinders shall be calibrated either “to deliver” or “to contain.” Style II and Style III cylinders shall be calibrated “to contain.” The cylinders shall be calibrated at 20 °C and the volumetric tolerances shall be in accordance with Table 1. (See Practice E542 for calibration definitions and procedures.)
Graduated cylinder - Wikipedia
A graduated cylinder is meant to be read with the surface of the liquid at eye level, where the center of the meniscus shows the measurement line. Typical capacities of graduated cylinders are from 10 mL to 1000 mL.
In the graduated cylinder shown in Figure 1, the mL graduations are marked and can be read with certainty. All graduated glassware is read with one estimated digit, so this measurement is recorded correctly to the nearest 0.1 mL, with an understood uncertainty of ± 0.1 mL. In reading digital equipment, all the digits shown are recorded.
Graduated Cylinder: Types, Uses, Calibration, Advantages, …
2024年1月27日 · A graduated cylinder, also known as a measuring cylinder, is a laboratory glassware designed for precise measurement of liquid volumes. It features a cylindrical shape with calibrated horizontal lines, allowing for accurate readings of incremental volume changes.
Measuring the Volume of Liquids - Harper College
The tolerance on graduated cylinders is about 1%. Volumetric flasks, burets and pipets are the most accurate with tolerances of less than 0.2%. To achieve these accuracies the person using the device needs to use the proper technique and the measurements need to made at the temperature for which the glassware was calibrated (usually 20 degrees C).
Mass of grad cylinder with liquid: 28.02 g +/- 0.01 g Volume of liquid: 3.00 mL +/- 0.05 mL Since density = mass/volume, the student calculates the experimental density value:
Graduated Cylinder: Definition, Types, Sizes, Uses
Class A graduated cylinders are more accurate than class B graduated cylinders. Class A cylinders have a tolerance of ±0.02 mL, while class B cylinders have a tolerance of ±0.08 mL. There are two main types of graduated cylinders: tall-form and short-form.
