A measuring pipette is used to measure specific amounts of liquid. There are many different kinds but they help you accurately measure and transfer small amounts. A transfer pipette is essentially an eye-dropper, they typically do not have measurements on them.

What is better to use in measuring smaller volumes of liquids the graduated cylinder or the pipette?
The pipette, as it can be used to dispense microliters [liters * 10 to the power of -6] .
What would happen if the student did not remove air bubbles from a pipette before delivering the liquid?
If the bubbles are not removed from a pipette, there will be less liquid inside the pipette than what was measured. The density will be lower as well.
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.
Is lead a better conductor of heat than glass?
Yes, lead is a metallic solid, and therefore facilitates the transfer of heat (energy) better than other solids.
What is the advantage of using a Buret?
the burette is more accurate than the pipette as it contains marks like a ruler so you are able to clearly identify the volume. However, with a pipette you can only measure the volume nearest to the ml.
Is measuring pipette better than transfer pipette?
yes

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.
Why bulb of wbc smaller than rbc pipette?
Rbc pipette is bigger than the wbc pipette to dilute the blood with fluid.
Why is it important to calibrate a pipette prior to it being used to make up standard solution?
Pipettes are used to move specific volumes of fluid between containers. For very small volumes, or very precise applications, a large error in the desired fluid volume can have a very large impact. Calibrating a pipette ensures that the volume desired is the volume collected. Proper sealing of pipette tips can also have a large impact on fluid volumes collected.
Difference between rbc and wbc pipette?
RBC pipette has graduations up to mark 101 while WBC has graduations up to mark 11. The size of the bulb of RBC pipette is larger than the bulb of WBC Size of the lumen(the hollow structure)in RBC is smaller than that of the WBC pipette
Why pipette is more accurate when determine the density of water?
because electronic pipette has the accuracy 0.01 microliter than burette.
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 Fiberglass measuring tape?
A measuring tape made of fiberglass. I have 3, very smooth and much better than steel tapes.

What piece of laboratory equipment is best suited for accurately measuring the volume of liquid?
use a graduated cylinder with the lowest capacity (greater than 26ml) if extreme accuracy is needed, (as I suspect with the small amount stated) I might use a scale, measuring by weight instead of volume (dropper may be needed to add to weight needed).... but you must adjust weight according to specific gravity or the only accurate liquid measured by 25.3 grams weight would be WATER :P
