![]() A graduated cylinder is used to measure volumes of liquids. It is a good idea to make this latter transfer over a sink. Flask tongs are used only to handle flasks use beaker tongs for beakers. Graduated cylinders are unstable so transfer liquids into the labeled beaker first and then pour from the beaker into your graduated cylinder. Carefully pour the amount of reagent that you will need, not extra, into the beaker and then close the reagent bottle. The stopper of the reagent bottle should be held during transfer or, if it is flat, placed upside down on the counter. Liquid Transfer Take an appropriately sized, labeled beaker to the reagent shelf. Be sure to put the right lid on the right bottle and return the bottle to its place on the shelf. If a spatula is provided at the reagent bottle, you may use it. Don't tip the bottle up high and let the contents pour out. Many solid chemicals can be easily transferred by tipping the bottle and slowly rotating the bottle back and forth. When you take the top off the reagent bottle, don't lay it down (risks contamination). Take a labeled beaker to the reagent shelf where the chemicals are kept. It is usually easier to transfer solids to a wide mouthed container such as a beaker. Sold in package of 6.Figure 3 : Using a piece of weighing paper to transfer a solid.
