I read today that the FAA has extended the timeline in which it will be inspecting all charter operations specifications section A008 for compliance with operational control requirements.
We have three sizes of volumetric flasks to choose from: 100, 250 and 500 milliliters and they feature a single etched line or graduation to denote the fill-to-line at the chosen volume. Each size flask is specifically made for preparing solutions that correspond to its nominal value. For example, a 250 ml volumetric flask is the appropriate choice only when preparing a solution with a total volume of 250 ml.
In the United States, the most common standard sizes for liquor are 750ml (milliliter), one liter and 1.75 liter. Miniatures are 50ml. SOmetimes you'll find half size bottles at 375ml. A milliliter is 1/1000 of a liter. One ounce is about 30ml. One liter is about 34 ounces.
