when the beaker has rated capacity of 10 ml, does it mean that it has to be filled to the brim?

• Chemistry -

No. Chemical beakers usually have an etched line in the glass where the liquid level is supposed to be when "full"

• Chemistry -

I didn't know that. I guess I always used "backward" beakers. Isn't technology great?

• Chemistry -

I answered based upon what I remember from college and high school chemistry. That was over 50 years ago. Apparently I was wrong.

There are such things as calibrated beakers. Some are shown at

For info on the "rated capacity" of a beaker, see

No, you probably are not wrong and I didn't doubt you. Your schools may have had the money to buy those calibrated beakers and mine didn't. Those calibrated beakers really are quite nice.
