RE: MEASURING ACCURATELY

Louise:
To measure viscous liquids accurately, I always do it by weight (with a
calculator to correct for specific gravity, if neccesary).  Actually, with
modern top-pan balances, it is usually easier to weigh out liquids than to
use volumetric glassware.
Good luck,

Hello histonetters

I want to ask a REALLY DUMB question: How does one accurately measure out
Tween 20 ( pipette, measuring cylinder)? It is so  viscous that I always
doubt that i have washed out/expelled the correct amount.

Thanks
