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.
Which tool will be the best tool to measure 20 millimeters of water?
Measuring Milliliters of water (volume) could be readily done using a graduated cylinder, pipette, syringe. A measurement of milimeters of water is essentially meaningless as how much water it would take to reach a given "length" would depend on the size of the vessel holding it.
Name of a glassware used to measure volume of a liquid exactly 65ml?
To measure a volume of liquid, laboratory instruments known as glassware are used. The commonly used glassware are burettes, pipettes, volumetric flasks and graduated cylinders.
What is used to measure a small quantity of liquid most accurate reading?
A graduated cylinder is typically used to measure small quantities of liquid with the most accurate reading. These cylinders are designed to provide precise measurements and are commonly found in laboratory settings.
Why does the liquid move into the siphon when air is removed from the siphon by the pipette?
When air is removed from the siphon by the pipette, the atmospheric pressure pushes the liquid into the siphon to fill the vacuum created. This creates a pressure difference between the two ends of the siphon, causing the liquid to flow into it.
What is a Mohr Pipette used for in chemistry?
A Mohr pipette is a type of pipette that measures the volume of dispensed liquids. It is less accurate compared to a volumetric pipette.
Why is a volumetric pipette used for measuring out the hydroxylamine?
To get a very accurate volume of hydroxylamine.
Why is a volumetric pipette more accurate than a graduated pipette?
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.
When measuring a small quanity of liquid which instrument would permit the most accurate reading?
Volumetric pipette.
What glassware provides the most accurate volume?
The glassware that provides the most accurate measurement of volume is the measuring cup. A glass measuring cup has lines on it to give an accurate reading.
What are the differences between a volumetric pipette and a serological pipette in terms of their design and usage in laboratory settings?
A volumetric pipette is designed for precise measurement of a specific volume of liquid, typically with a single graduation mark. It is used for accurate transfer of liquids in laboratory settings. On the other hand, a serological pipette is designed for general liquid transfer and has multiple graduation marks for different volume measurements. It is commonly used for less precise measurements and general liquid handling in the lab.
What is used of volumetric pipette?
The purpose of a volumetric pipette is to deliver a precise amount of a liquid. The label on the pipette indicates the volume delivered (e.g. 10.00 mL).
Should you blow out a volumetric pipette?
No, it is not recommended to blow out a volumetric pipette as it can introduce inaccuracies in the measurement due to variations in pressure or volume expelled. It is better to drain the contents by gravity and touch off the tip on the receiving vessel to ensure the correct volume is dispensed.
How to properly read a serological pipette for accurate measurements?
To properly read a serological pipette for accurate measurements, follow these steps: Hold the pipette vertically and at eye level. Check the calibration marks on the pipette to ensure it is the correct volume. Align the meniscus (the curved surface of the liquid) with the desired calibration mark. Read the volume at the bottom of the meniscus for an accurate measurement. Make sure to account for any liquid clinging to the walls of the pipette. By following these steps, you can ensure precise and accurate measurements when using a serological 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.
How do you properly use a graduated pipette for accurate measurement in the laboratory?
To properly use a graduated pipette for accurate measurement in the laboratory, first ensure the pipette is clean and dry. Then, draw the liquid into the pipette slowly and steadily to the desired volume, making sure the meniscus aligns with the calibration mark. Hold the pipette vertically to allow any excess liquid to drain back into the container. Finally, touch the tip of the pipette to the side of the receiving vessel to release the remaining liquid.
