Watch Glass

Watch Glass Introduction

Watch glass is made of glass, round shape, slightly concave in the middle, similar to the evaporating dish;
Can be used to do some of the work of evaporating liquid, it can make some of the surface area of the evaporating liquid increase, so as to accelerate the evaporation;
Can be used as a lid on a evaporator or beaker to keep dust from falling,
Can be used as a container to temporarily hold solid or liquid reagents,

Tips

Wash and dry surface dish before using. The watch glass is widely used, but no matter what kind of instrument is used, it must be used according to the use of various instruments.

For example, for gas chamber identification, use two surface dishes, use the ground flat syngas chamber, and attach a piece of test paper soaked with reagent to the upper surface dish. The identified compound is placed on the lower one On a surface dish, warm it if necessary, observe the gas generated during the reaction, and identify the gas from the color change of the reagent.

For example, when observing white precipitates or turbid materials, put a piece of black paper on the bottom wall of the surface, and the white products can be clearly seen. Such as making various instrument lids, just use its arc shape to place on the instrument mouth and stabilize it, but pay attention to select the watch glass according to the diameter of the instrument. Generally, the diameter of the surface dish should be larger than the diameter of the instrument by 1CM, which is more convenient to use. Such as the beaker lid, select a surface dish with a different diameter according to the beaker capacity.
