Any Lab & or Chemical Engineers in the the house ?

I need a easy way of measuring/pouring fluids in qtys of 2 oz or left. The general - dispensing-proportioning-diluting to concentrate to fluid is very small qts. Ie, I would need to measure out 60ml, 30ml, 22.5ml, etc etc.

So I came across graduated cylinders which seem to do the trick.
Don't laugh but is there any better ones out there I should consider. Not crazy scientific accurate but nice, durable, easy to read would be nice.

I found these at a teachers supply store...

Looks good to me - better than pouring it into a MMO bottle to measure...

When measuring very small amounts of chemicals you may want to look into micro gas and liquid laboratory syringes. Google Glenco laboratory syringes.

For some reason I'm now thinking of Dennis Hopper in 'Speed' -- or rather 'On Speed' in his case.

If chefwong starts making lots of typos in next week's posts, we'll know he used the wrong measurement, and blew off a couple of fingers.

The technology (old now) that we used for measuring fluids (decreasing volumes) was calibrated flasks (20L to 1L), graduated cylinders (typically 50 ml to 500 ml), pipettes (20 ml to 0.1 ml), syringes (10 cc to 0.1 cc) micropipettes (down to fractions of a ul). Weighing was alawys an option. Various automated dispensers were available.

Chefwong is making a chocolate peanut butter mousse bomb dessert?

My addiction to auto detailing far exceeds ~oil~. Suffice to say, I have tons of various cleaners, etc and plan to cut them 1:40, 1:32, etc and due to my 24 oz bottles.....the good ole' Pyrex measuring cup at home ain't going to cut it these days ;-)


I was on a tool envy and looked at those pipettes that the doctors use......picked up a set of owens corning pyrex set ranging from 10, 20, 50 and 100 ml.

I don't know what they're called, but I've used glassware that looks like a graduated cylinder with a stopcock valve at the bottom. They are an excellent way of repetitively dispensing an exact amount of fluid.

Used in titration ...
