What is a 250 ml beaker used for?
Unlike plastic beakers, this more heavy-duty glass beaker can be used for mixing and gentle heating, and has thermal shock resistance – meaning it will withstand typical laboratory thermal variations common to chemistry processes (like heating and cooling).

How big is a 500ml beaker?
What is the uncertainty of a 25 ml beaker?
Making a measurement A 100-ml graduated cylinder with 1-ml graduation will have an uncertainty of +0.1mL. For a 25-ml graduated cylinder with graduation of 0.2 ml, the uncertainty is +. 02-ml (10% of 0.2 = . 02).
What is the uncertainty of 100 ml beaker?
For a 100 mL graduated cylinder, this would be an error of 0.5 to 1.0 mL. Measurements made with a graduated cylinder can be reported to three significant figures.
What do you use a 250 mL beaker for?
Beakers are used for mixing and gentle heating and will withstand typical laboratory thermal variations common to chemistry processes like heating and cooling. The graduations are approximate and not intended for accurate liquid measurement. These 250 ml Home Science Tools beakers are a great value!
Can a 250 mL beaker be heated in an open flame?
This metric scale 250 ml beaker from Home Science Tools is an excellent value – especially when bought in bulk and turned into a beaker set! Designed with excellent mechanical strength, an extra large marking spot, a convenient pour spout, and high-quality borosilicate glass, this 250 ml beaker can be heated directly in an open flame.
What do you use a beaker for in chemistry?
Beakers are used for mixing and gentle heating and will withstand typical laboratory thermal variations common to chemistry processes like heating and cooling.
