What is the main advantage of using pipette in measuring the volume of liquid?
The main disadvantage of using a pipet in measuring the volume of a liquid is that you cannot dispense large quantities.
What are the difference between td and tc pipets?
The labels TC and TD mean "to contain" and "to dispense" respectively. What this means is that glassware can either be calibrated for the purpose of containing a solution or for the purpose of transferring and dispensing a solution. Most flasks will be labeled TC while most pipets and burets will be labeled TD.
How can I efficiently deliver a precise amount of liquid using a pipette?
To efficiently deliver a precise amount of liquid using a pipette, first ensure the pipette is calibrated and set to the desired volume. Then, immerse the tip of the pipette into the liquid and slowly draw up the liquid by gently pressing and releasing the plunger. To dispense the liquid, carefully release the plunger to deliver the precise amount. Be sure to hold the pipette vertically to prevent any spills or inaccuracies.
What happens if you use a dirty pipet?
A test may become unfair or the chemical you're using may cause a chemical reaction
When using a pipet can you state the volume of the aliquot without calculating it?
Yes, the volume of the aliquot is typically indicated on the pipette itself. Most pipettes have volume markings along the side that allow you to easily set and dispense the desired volume without needing to calculate it.

How do you transfer liquid chemicals?
Methods: using a pump, a liquid syphon, a funnel, pipettes, free flowing etc.
When using a graduated cylinder what is the lowest point of the liquid Called?
The meniscus. Make sure to always measure at that point. If your graduated cylinder/pipet/etc has the meniscus at 10 mL then the glassware has 10 mL in it.
A pipet delievers 9.98g of water at 20 degrees celsius What volume does the pipet deliver?
To calculate the volume of water delivered by the pipette, you need to convert the mass of water to moles using its molar mass (18 g/mol). Then, you can use the density of water (1 g/mL) at 20 degrees Celsius to convert moles to volume. The volume delivered by the pipette would be approximately 9.98 mL.
How do you use dropping Pipette?
An Epppendorf pipet is what is called a constant volume pipet. It consists of a barrel with a a push button on one end and a stem on the other. You attach a single use disposable tip to the stem. Some models allow you to set the volume to be dispensed, some are not adjustable. In use, , you depress the push button to the first stop, insert the tip into the liquid to be pipetted, and release the button smoothly to draw up the liquid. Then, transfer the pipet to the receiving vessel and depress the button past the first stop to the second stop, this dispenses the liquid and blows out the last drop to insure accuracy, then discard the tip before the next use. Every time you draw up liquid, you get the exact same volume, with very high precision.

How do you clean your pipet?
Fill a mug or a container with warm tap water. You are using warm tap water because, tap water contains microorganisms which will help flush out the chemicals and it is warm ,because warm water can cleanly stabilize your pipet so it is ready for it's next use. Pinch your pipet inside the water so it fills up to about 15-20 milliliters. Squirt in in the sink. Do the same thing for a few times. Atleast 5 times. Now your pipet is clean and ready for its next use.Why is it important to clean your pipet? It can contain chemicals from your previous experiment which will give inaccurate or wrong results and data.
What happens if you use a dirty pipet?

How does a thermos reduce heat transfer using convection?
A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other. Hope this helped
What is the difference between booster pump and transfer pump?
The centrifugal pump is use to transfer a larger flow rate of liquid in a low pressure stage, while the booster pump is use to transmit less volume of liquid in a high pressure stage.
