Description/Packaging | 144 pcs/carton |
Product Usage:
Beakers with handles are commonly used reaction vessels for simple chemical reactions because they have the same caliber up and down and are convenient for taking liquids. When there is a scale on the outer wall of the beaker, the volume of solution inside can be estimated. Some beakers will also have a small area on the outer wall that is white or has rough edges. In this area, you can use a pencil to write the name of the content. If there is no such area on the beaker, you can write the name of the contents on the label paper and stick it on the outer wall of the beaker for identification. When the reactants need to be stirred, they are usually stirred with a glass rod. When the solution needs to be moved to other containers, you can tilt the mouth of the cup toward the side with the special notch to pour the solution out smoothly. To prevent the solution from flowing down along the outside of the cup wall, you can use a glass rod to lightly touch the cup mouth, and the solution attached to the cup mouth will flow down (drainage) smoothly along the glass rod.
Practical Tips
Beakers with handles are used as reaction vessels for preparing solutions, dissolved substances and larger amounts of substances at room temperature or under heating.
1. When heating the beaker, an asbestos mesh should be placed on it to provide uniform heat. Do not use a flame to directly heat the beaker. Because the bottom of the beaker is large, direct heating with a flame will only burn part of the glass, causing uneven heating of the glass and causing it to burst. When heating, the outer wall of the beaker must be wiped dry.
2. When used for dissolution, the amount of liquid should not exceed 1/3 of the volume of the beaker. And stir gently with a glass rod. During the dissolving or diluting process, when stirring with a glass rod, do not touch the bottom or wall of the cup.
3. When holding liquid for heating, do not exceed 2/3 of the volume of the beaker. Generally, 1/3 of the volume of the beaker is appropriate.
4. When heating corrosive chemicals, cover the mouth of the beaker with a watch glass to prevent liquid from splashing out.
5. Do not use beakers to hold chemicals for a long time to avoid falling into dust and evaporating the water in the solution.
6. Do not use beakers to measure liquids.
