WebFour main types of volumetric glassware are common: the graduated cylinder, the volumetric flask, the buret and the pipet. These have specific uses and will be discussed individually. There are some points that are common to all types, however. These involve cleanliness and how to read volumes accurately. WebLet's say you're making a normal saline solution of 0.15M. You can be off by +/-3% of the volume and it rounds to 0.15M. If you only have one sig. fig. (0.1M) it's +/-30%! Plus the range of acceptable variability for many solutions is really wide. Now, knowing which ones you can fudge and which you can't is the real galaxy brain... WebAnswer: I believe what you mean is ‘more precise’. The difference between the two is for another day.
