Graduated pipettes are not as accurate as volumetric pipettes, because each graduation line is not individually calibrated, and any imperfection in the internal diameter will have a greater effect on the volume delivered. In volumetric pipettes, the diameter of the pipette where the graduation mark is located is significantly smaller because the majority of its volume is located in the bulb.
What else can I help you with?
What is more precise a pipette or graduated cylinder?
A pipette is generally more precise than a graduated cylinder. This is because pipettes are designed to deliver specific volumes of liquid accurately, while graduated cylinders are typically used for measuring approximate volumes.
What is better to use in measuring smaller volumes of liquids the graduated cylinder or the pipette?
For measuring smaller volumes of liquids, a pipette would be better as it offers higher precision and accuracy compared to a graduated cylinder. Pipettes are designed to dispense and transfer specific volumes of liquids accurately, making them ideal for precise measurements in laboratory settings.
Why would a scientist use a graduated cylinder instead of beaker?
A Volumetric Pipette is the most accurate and used for titration calculations, if you include that as a type of pipette then it is FAR more accurate than a graduated cylinder. A beaker is very inaccurate so don't even go there.
What are the key differences between a serological pipette and a volumetric pipette in terms of their accuracy and precision in measuring liquid volumes?
Serological pipettes are generally more accurate and precise than volumetric pipettes when measuring liquid volumes. Serological pipettes have graduations along the entire length, allowing for more precise measurements, while volumetric pipettes have a single graduation mark, which can lead to slightly less accuracy. Additionally, serological pipettes are typically calibrated to deliver a specific volume, while volumetric pipettes are calibrated to contain a specific volume.
What is the difference between pipette and graduated cylinder?
A pipette is a more precise measuring tool used for transferring small volumes of liquid accurately, while a graduated cylinder is used to measure larger volumes. Pipettes typically have a finer scale for precise measurements, while graduated cylinders are suitable for general volume measurements.
Who among the following is the more accurate in measurement the pipette or the volumetric pipette?
Theoretically a graduated cylinder...but if the only graduate I've got holds five liters with graduations 100 ml apart and I'm trying to measure to the milliliter, the pipette would be more accurate.
What is the function of volumetric pipette?
A volumetric pipette is used to accurately measure and transfer a precise volume of liquid. It is designed to deliver a single, specific volume of liquid with high accuracy and precision. Volumetric pipettes are commonly used in analytical chemistry and laboratory settings where precise measurements are crucial.
What is more precise a pipette or graduated cylinder?
A pipette is generally more precise than a graduated cylinder. This is because pipettes are designed to deliver specific volumes of liquid accurately, while graduated cylinders are typically used for measuring approximate volumes.
What type of measuring device should be used to measure ml of liquid for compounding?
A graduated cylinder or a precision volumetric flask is ideal for measuring milliliters of liquid when compounding. Graduated cylinders provide a clear scale for accurate measurement, while volumetric flasks ensure precise volume for solutions. For smaller quantities, a syringe or a pipette can also be used for more accurate dosing. Always ensure that the measuring device is calibrated and appropriate for the volume being measured.
What is better to use in measuring smaller volumes of liquids the graduated cylinder or the pipette?
For measuring smaller volumes of liquids, a pipette would be better as it offers higher precision and accuracy compared to a graduated cylinder. Pipettes are designed to dispense and transfer specific volumes of liquids accurately, making them ideal for precise measurements in laboratory settings.
What would you use to measure volume?
It depends on the amount you want to take. If it is microlitres, you can use a micropipette, millilitres, a pipette (a burette would be more accurate), and if greater than that, it is best to use a large graduated cylinder. A graduated cylinder is more inaccurate than a pipette, but at volumes of 500ml for example, it is impractical to use a pipette.
Could a 25 ml volumetric flask be replaced by a 25 ml pipette to measure the solution poured into a conical flask for titration?
As the pipette is far more accurate than a flask by a factor 10 to 100 one should NOT use a volumetric flask except for standard volumes over 100 ml.
Why would a scientist use a graduated cylinder instead of beaker?
A Volumetric Pipette is the most accurate and used for titration calculations, if you include that as a type of pipette then it is FAR more accurate than a graduated cylinder. A beaker is very inaccurate so don't even go there.
What tool would you use to measure out 50 mL of water?
Depending on how accurate you want to be you can use a variety of methods. Common methods include the following (with increasing level of accuracy) 1) graduated cylinder 2) volumetric pipette. 3) Calibrated micro-pipette (may require more than one transfer)

Why measuring cylinder is more precise than pipette?
Precision describes the repeatability of results, i.e. whether you get the same answer each time you measure something. Used correctly, there is no reason why a measuring cylinder would be the more precise. The exception is if you are using an inappropriate size of pipette, as it's difficult to be precise near the bottom of its range. Too large a measuring cylinder could also be imprecise.
What measures mililtiers?
A pipette, Autopipette, burette, a graduated cylinder for more than 1ml. etc
