Somewhere -- someone asked about measuring *very* small amounts of liquids. The "classic" method is to use a Pipette -- This thing is a small diameter tube - usually glass, calibrted in ... smal fractions of milliliters -- or whatever. I inquired at my local pharamcy ("Chemist" to those in Jolly Old..) about buying one for myself ... and *I* think he overreacted, for some unknown reason. After talking him out of calling the riot squad (??? I have **NO** idea what the #$!# was going on), I discovered a much cheaper and more durable substitute. I bought two of them ....
They are called brand name <Basis> "Oral Syringe with Bottle Applicator",
Disrtibuted by PolyMedica Health Care, Inc., Golden Colorado, 80401.
Essentailly, it is similar to an hypodermic syringe without the needle. It has a capacity of 10 ml; graduated in tenths of a ml - ideal for measuring Rodinal.
It is designed for admistering small amounts of liquid medicines to infants/ children, so is obviously chemically inert.
I've used one of these successfully for some three or four years - with no problems.
Not bad for US$1.99 each.
Incidentally - Made in Denmark.
