Gotta Be A Better Way to Get DME into a Flask...

[ajdelange]

A graduated cylinder (which is far more accurate at measuring liquid volume) is off by at least 5%.

Maybe for Student grade but a Class A would be more like half a percent and Class B a percent (depending on the size of the cylinder). For a 1L cylinder, e.g. its 0.3% (3 mL) for Class A and 0.6% (6 mL) for Class B.

I have a teeny tiny funnel (99 cents at your local hardware). I put the dry flask onto my scale, tare and pour DME through the funnel into the flask to the right weight. I add water to the appropriate level, then swirl to combine and boil.

This doesn't solve your problem of wanting to eliminate your funnel, but it won't result in sticky DME funnel syndrome either.

those markings on the side of an erylinmeyer flask are off by at least 20%! A graduated cylinder (which is far more accurate at measuring liquid volume) is off by at least 5%.

Instead try this. I like your idea of weighing the DME in the flask on your scale. To add 1L of water, add 1000g or 1Kg of water to your flask.

Palmer's good book says to use 100g DME to 1L water.

That is money. I like that.
