Description
50ml glass volumetric flask
Volumetric flask is a precise instrument used for the preparation of accurate molt solutions of certain substances.
Pre-made solution
(1) Check whether the bottle stopper is leaking before use. Add a small amount of water to the bulk bottle, plug the stopper, use the index finger against the stopper, use the five fingers of the other hand to hold the bottom of the bottle, and put the bottle upside down. If it is not leaking, stand upright, rotate the stopper 180 degrees and plug it tightly, and then stand upside down if it is not leaking.
(2) Put the solid solute accurately weighed in a beaker and dissolve it with a small amount of solvent. The solution was then transferred along the glass rod into a volumetric flask.
In order to ensure that all solutes can be transferred to the volumetric flask, the beaker should be washed many times with the solvent, and the washing solution should be transferred to the volumetric flask.
(3) When the liquid level added to the volumetric flask is about 1 to 2 cm away from the mark line, it should be carefully dropped with a dropper, and finally the meniscus surface (concave liquid level) of the liquid is just tangent to the scale line.
(4) Cover the stopper tightly, invert and shake to make the liquid in the bottle mixed evenly
