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.
What else can I help you with?
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.
What is the difference between volumetric pipette and micro pipette?
Pipettes are used to transport liquids. Graduated pipettes are marks similarly to graduated cylinders, indicating different calibrated volumes. Volumetric pipettes only mark a single volume of measurement, and as such require different pipettes for different quantities.
When you use a volumetric conical flask and pipette explain the accuracy aspects of this equipment?
A volumetric conical flask is used for accurate volume measurements due to its precise calibration markings, typically with an accuracy within ±0.05 mL. When paired with a pipette, which allows for the precise transfer of fluids, the overall accuracy of measurements is enhanced. However, proper technique, such as ensuring the meniscus aligns with the calibration mark and avoiding parallax errors, is crucial for achieving accurate results.
What pieces of equipment that are used in volumetric analysis?
In volumetric analysis, essential equipment includes a burette for accurately dispensing liquid reagents, a pipette for measuring precise volumes of solutions, and a volumetric flask for preparing standard solutions of known concentration. Additionally, a funnel is often used to aid in transferring liquids, and a balance is utilized to weigh solid reagents. These tools ensure accurate measurements and reliable results in titrations and other quantitative analyses.
What would be the precaution for drop left in pipette?
For the majority of pipettes the last drop should be left in the pipette; read the recommendation from the pipettes catalog.
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).
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.
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.
Why is a volumetric pipette used for measuring out the hydroxylamine?
To get a very accurate volume of hydroxylamine.
Why should you not blow out the small amount of solution that remains in a pipette when measuring liquid?
The calibration of a pipette is made taking into account this small volume.
Why should you not blow out the small amount of solution that remains in pipette when measuring liquids?

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.
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.
When measuring a small quanity of liquid which instrument would permit the most accurate reading?
Volumetric pipette.
Can the NaOH solution be blown out of the pipette to reduce the time for the transfer?
Blowing out the NaOH solution from the pipette is not recommended as it can introduce impurities, affect the accuracy of the transfer, and pose a safety risk. It is better to dispense the solution using the appropriate technique for accurate and safe measurements.
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.
