You use the glass beaker is fake?

The glass beaker is a reaction container with a large amount of reactants. It is not a gauge itself, so it cannot be used for accurate measurement. Of course, we are very clear about this. What we are going to talk about today is the scale problem on the glass beaker. wholesale glass beakers,beaker bottle,800ml beaker,glass beaker low form,bomex beaker with scale According to the [Capacity grading table of low beaker and high beaker] in the national standard for laboratory glass instrument beaker [GB/T 15724-2008] : For 100ML, the scale is 20 and the highest score scale is 80(note that 80 is not 100). This is because the beaker is used as a reaction vessel, so there needs to be a certain amount of space to prevent the liquid from splashing.wholesale glass beakers,beaker bottle,800ml beaker,glass beaker low form,bomex beaker with scale
At present, many LABS buy beakers with full scale, but they do not know that a 100ML beaker that meets the national standard will not mark the scale of 100, which eventually leads to the formation of wrong qualitative thinking. On the other hand, I think a beaker with a scale of 80ml is a knockoff. In fact, the beaker scale is not very accurate, the allowable error is generally ±5%, so the word APPROX is printed on the scale, which means “approximate volume”. Therefore, it cannot be used as a measuring device!
