Is there a 5 liter volumetric flask?
These PYREX® 5L volumetric flasks provide improved lab convenience, broad selection and precise volume measurement. The strength of these flasks has been increased appreciably through machine-blown bodies to which are sealed heavy-tubing necks tooled for No. 38 Standard Taper pennyhead glass stoppers.
How many liters is a volumetric flask?
Volumetric flasks are of various sizes, containing from 1 milliliter to 20 liters of liquid.
How big is a volumetric flask?
Volumetric flask sizes are available with 100ml, 250ml, 500ml, or a 1,000ml volume capacity.
How big is a 250ml volumetric flask?
Class A, tolerance, ±0.120mL as per ASTM-E288. Calibrated to contain. Flask stands 9″ tall, and has a bottom diameter of 80mm. Neck has a diameter of 18mm.
Why is a volumetric flask used?
A volumetric flask is lab glass or plasticware used to prepare a solution. It is used to make up a solution to a known volume. Volumetric flasks are used to measure volumes much more precisely than beakers or Erlenmeyer flasks.
What is the purpose of a volumetric flask?
Volumetric flasks are calibrated with great accuracy, for the purpose of preparing dilutions and solutions of a precise volume.

How to use a volumetric flask
- Add your solute to your solution.
- Add enough solvent to dissolve the solute.
- Keep adding your solvent until it gets close to the line marked on the volumetric flask.
- Use a pipette to fill the flask.

What is the uncertainty of a 5 mL graduated cylinder?
What is the uncertainty of a 1l volumetric flask?
± 0.1 mL
All graduated glassware is read with one estimated digit, so this measurement is recorded correctly to the nearest 0.1 mL, with an understood uncertainty of ± 0.1 mL.
Why do we use a volumetric flask?
Use volumetric flasks for precise measurement
A volumetric flask is lab glass or plasticware used to prepare a solution. It is used to make up a solution to a known volume. Volumetric flasks are used to measure volumes much more precisely than beakers or Erlenmeyer flasks.

How do I calculate uncertainty?
To calculate uncertainty, you will use the formula: best estimate ± uncertainty, where the uncertainty is the possibility for error or the standard deviation. You should always round your experimental measurement to the same decimal place as the uncertainty.
What is the tolerance of a 5ml pipette?
±0.030ml
5ml capacity, 0.05ml blue graduation lines, marked every 0.5ml. Class A, tolerance, ±0.030ml . Calibrated for delivery to jet. Pipette measures 14.25″ in length, and has a body diameter of 0.35″.
What is a 250 ml Erlenmeyer flask used for?
Erlenmeyer flasks or titration flasks are used to contain liquids. They are also used for mixing, heating, cooling, incubation, filtration, storage, and other liquid-handling processes. This 250ml Erlenmeyer flask is made of borosilicate glass.
What is error and uncertainty?
‘Error’ is the difference between a measurement result and the value of the measurand while ‘uncertainty’ describes the reliability of the assertion that the stated measurement result represents the value of the measurand.
How is standard error calculated?
How do you calculate standard error? The standard error is calculated by dividing the standard deviation by the sample size’s square root. It gives the precision of a sample mean by including the sample-to-sample variability of the sample means.
What is the volume of a pipette?
Micropipettes are available in different volumes ranging from 0.1 µl to 10,0000 µl.
Is volumetric pipette TC or TD?
Volumetric pipets, sometimes called transfer pipets, are the most accurate pipets. They generally deliver the specified volume ±0.1%, an error of a few hundredths of a milliliter. Most volumetric pipets are marked TD (to deliver) and are drained by gravity.
