Dear Mr Bowen that's a very important technical question of broad general interest to many RG members. For a potentially useful guide on how to deal with this problem, please have a look at the following link:

Eliminating Inaccuracy in Precision Weighing Caused by Static Charge

Also please see:

Electrostatic Charges and Their Effects on Weighing - How to deal with static samples to achieve fast and accurate results

This practically important question has also been frequently discussed on RG before. Thus it might be interesting having a look at the answers given to the following closely related questions:

Is there any special trick to weighing high static compounds accurately on an analytical balance?

Can anyone suggest a way to deal with static electricity build up in organosilica powders?

I hope this helps. Good luck with your work and best wishes, Frank Edelmann

Hi. To remove the static charge from plastic beakers , wipe the plastic beaker with a used dryer sheet, the type sold for the purpose of removing “static cling” from clothing.

Hey Mr Bowen It happens to me a lot, I come from Cuba (high humidity) and doing chemistry in middle Germany (very dry) is most of the time complicated due to the static charge. My advice, what I was taught by a former colleague is: to place a piece of aluminum foil (30x30 cm) on your plateau and then place your plastic beaker, or (epi, plastic cylinder, etc) and your spatula on top of it. Also a piece of metal close to you, like a retort stand. You must touch one of them before starting weighing your sample, do it several times and also in between the process just in case.

Good luck ;-)

I suggest that you check also this RG discussion:
