What size Beaker do I need for my lab?
Choose the right size for your lab needs, ranging from 50 ml to 2000 ml. Made of high-quality borosilicate glass that can be heated directly in an open flame and withstand thermal shock, Pyrex® beakers are primarily used for mixing and heating. Graduations are approximate and not intended for accurate liquid measurement.
What do the numbers on a 250 mL beaker mean?
For instance, a 250 mL beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 mL of volume. These marks are not intended for obtaining a precise measurement of volume (a graduated cylinder or a volumetric flask would be a more appropriate instrument for such a task), but rather an estimation.

Beaker Definition & Meaning - Merriam-Webster
beaker: [noun] a large drinking cup that has a wide mouth and is sometimes supported on a standard.
How tall is a beaker?
Standard or "low-form" (A) beakers typically have a height about 1.4 times the diameter . The common low form with a spout was devised by John Joseph Griffin and is therefore sometimes called a Griffin beaker.
What is a flat beaker called?
Flat beakers (C) are often called "crystallizers" because most are used to perform crystallization, but they are also often used as a vessel for use in hot-bath heating. These beakers usually do not have a flat scale. The presence of a spout means that the beaker cannot have a lid.
What is a beaker in a lab?

Why do beakers need to be covered?
However, when in use, beakers may be covered by a watch glass to prevent contamination or loss of the contents, but allowing venting via the spout. Alternatively, a beaker may be covered with another larger beaker that has been inverted, though a watch glass is preferable.
What is the difference between Griffin and Berzelius beakers?
They differ mainly in the ratio of their height to diameter. Further, the Griffin beakers have graduating marks for measuring with an accuracy of +/- 5%. The Berzelius beakers have no graduations and are popular for mixing and as lab themed drinking vessels.

What size breaker is used for 30A?
The 80% of a 30A circuit breaker is 24A. This way, a 30A circuit can be safely used for 24A circuit. In other words, a load circuit having 24A, the appropriate size of breaker would be: 24A / 0.8 = 30A. An exact 100% rated for 30A circuit breaker can be used for 30A non-continuous load.
What is the CB size of a circuit?
CB size should be 125% of the circuit current.
What is a Circuit Breaker?
Control (make or break) a circuit manually or by remote control under normal and fault conditions.
What happens when a circuit breaker is short?
In case of fault or short circuit when the value of current exceeds the circuit breaker current, It will automatically trip i. e. break the circuit from the main supply. For example, a 30 amp circuit breaker will trip at 30 amp no matter if is it continuous or non continuous load.
Why is a correct size circuit breaker needed?
In case of other (over or lower) size instead of correct sized circuit breaker, the circuit, cables and wire even the connected device may heat up or in case of short circuit, it may start to smoke and burn. That’s why a correct size circuit breaker is needed for smooth operation.
