Although the choice of reagent bottles is important, the use of reagents should not be ignored

There are many kinds of reagents, which are pure chemicals used to realize chemical reactions, research experiments, teaching experiments, etc. Lab Reagent Bottle,Reagent Glass Bottle 250ml,Amber Reagent Bottle  Choosing the appropriate reagent bottle according to the nature of the reagent is very important for the preservation of the reagent and the smooth progress of the experiment. Lab Reagent Bottle,Reagent Glass Bottle 250ml,Amber Reagent Bottle  But many people may overlook one point. In fact, the use of chemical reagents cannot be ignored.
Use of solid reagents:
Reagents are divided into two categories: solid reagents and liquid reagents. Solid powder reagents are generally stored in wide-mouth reagent bottles, and clean horn spoons can be used when taking them. General solid reagents can be weighed on clean paper or surface utensils. Reagents with special properties such as corrosiveness and strong oxidation It should be weighed in a glass container.
Liquid reagent access:
Liquid reagents are generally stored in narrow-necked reagent bottles, and the pouring method can be used to take out the liquid reagents. Remove the bottle cap and place it on the desktop. Hold the label side of the reagent bottle with your hand. Gradually tilt the bottle to let the reagent flow into the test tube along the clean test tube wall or into the beaker along the clean glass rod. When taking liquid reagents quantitatively, you can take them with a graduated cylinder or pipette, and choose different measuring barrels according to the amount.
It should be noted that in order to avoid contamination of the reagent or skin burns, the reagent should not be in contact with the hands. When taking reagents, try not to take more reagents, and the more reagents can not be poured back into the reagent bottle. After taking the reagents, the bottle caps should be properly capped, and the caps and droppers should not be misplaced. After using them, put the reagent bottles back in their original places.
