Question about glassware measurements.

(1/1)

Dhisbdj:
Why do different glassware give different measurements when measuring the same amount ? I measured 15 ml on volumetric flask but got less using graduated cylinder.

Borek:
A lot depends on the glass accuracy and technique used. Not knowing what and how you did, it is impossible to comment.

jeffmoonchop:
Cylinders shouldn't be used if accuracy is needed. Volumetrics are more accurate. But you can buy different grades of glassware, Ideally the volumetric should be A rated. And make sure your meniscus is sitting on the line.

jeffmoonchop:
Also if you pour the liquid from the volumetric into the cylinder, you'll leave some behind and get less in the cylinder.
