I don't like them since there is ample opportunity for powder to float out when tipping up and tapping out (even though you have reweighed and calculated the difference).
Can anyone point me to a paper on this?
I propose to weigh (mgs) into a 50ml beaker and dissolve in solvent in the beaker then transfer to the volumetric with plenty of washings - taking care not to lose standard down the outside of the beaker spout.
I suppose there is less chance of losing powder if you spoon it near to the spout end?
