Dear Researchers,

I purchased some lyophilized human hemoglobin powder from Sigma (https://www.sigmaaldrich.com/GB/en/product/sigma/h7379) and I'm experiencing some trouble with hydrating it in PBS. Its not a problem of solubility but the highly static nature of the powder and hence the nearly impossible task of getting the powder out of the bottle.

Has anyone experienced this before and if so how was the powder removed from the plastic bottle without it getting on every single surrounding surface including the outside of the bottle?

Thank you all for your insight.

Best wishes,

Riana
