This instrument is an electronic micropipette.
The most accurate laboratory apparatus used in measuring the volume of liquid is a burette. Burettes are designed to deliver precise volumes of liquid with high accuracy, often to within 0.05 mL or better. They are commonly used in titrations and other quantitative analyses where precise volume measurements are critical.
If you are talking about a liquid measuring cup (or a breaker) you must get eye level with the cup and where the line of water (meniscus) meats the line on the cup you have the correct amount.
In a lab, a measuring cup is typically used to accurately measure and dispense liquid reagents or solvents. To use a measuring cup, simply pour the liquid into the cup up to the desired measurement line, ensuring the measurement is read at eye level for accuracy. It is important to handle the measuring cup carefully and avoid spillage to prevent contamination or inaccuracies in experiments.
The main disadvantage of using a pipet in measuring the volume of a liquid is that you cannot dispense large quantities.
The lower meniscus is important in determining the volume of a liquid in a graduated cylinder because it is the curved surface at the bottom of the liquid level. When measuring volume, the measurement is taken at the bottom of the meniscus to ensure accuracy, as the liquid tends to curve slightly at the edges due to surface tension.

Graduated cylinder: Typically used for measuring liquid volume with good accuracy. Beaker: Can be used for approximate measurements of liquid volume. Pipette: Allows for precise measurement and transfer of liquid volume. Burette: Commonly used in titration experiments to measure liquid volume delivered. Volumetric flask: Used to prepare solutions of known precise volumes.
A graduated cylinder is a common measuring apparatus used to measure the volume of liquids accurately. It is a tall, narrow container with volume markings along its side to indicate the amount of liquid present.
When measuring with a graduated cylinder, you pour the liquid into the cylinder to a precise level. Read the measurement at the bottom of the meniscus, which is the curved surface of the liquid. Be sure to read the measurement at eye level for accuracy.
A graduated cylinder, measuring cup, or beaker can be used to measure liquid volume accurately. It is important to use the correct measuring tool and ensure the meniscus (the curved surface of the liquid) is at the correct measurement line for accuracy.
A graduated cylinder is the most appropriate tool for measuring the volume of water accurately. It has clear markings for measuring different volumes of liquid and is designed specifically for this purpose.
Glass laboratory apparatus are usually resistant to acids. Wood laboratory apparatus are usually used for mixing dry elements. Metal laboratory apparatus are for mixing liquid elements and rubber apparatus are usually used for testing and measuring.
