Beakers are often graduated, that is, marked on the side with lines indicating the volume contained.
For instance, a 250 ml beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 ml of volume. These marks are not intended for obtaining a precise measurement of volume (a graduated cylinder or a volumetric flask would be a more appropriate instrument for such a task), but rather an estimation. Most beakers are accurate to within ~10%.

Borosilicate glass has excellent chemical and physical properties.The linear expansion cofficient of the primary hydrolyzable glass is 3.3 for applications requiring excellent chemical resistance and thermal resistance (including thermal shock resistance), as well as high mechanical stability. It is a typical glass for chemical equipment.
The presence of a spout means that the beaker cannot have a lid. However, when in use, beakers may be covered by a watch glass to prevent contamination or loss of the contents, but allowing venting via the spout. Alternatively, a beaker may be covered with another larger beaker that has been inverted, though a watch glass is preferable.
The marking is robust and can be used in a laboratory test with a glass graduated cylinder. Wide edges and tapered spout for easy filling and pouring.
The dimensions are all measured by hand, so there may be some errors. Please contact us for the specific freight.

Small experimental knowledge
A beaker is used as a reaction vessel for arranging a solution at room temperature or under heating, dissolving a substance and a relatively large amount of a substance.
1. When heating the beaker, place an asbestos net to evenly heat. Do not directly heat the beaker with flame. The outer wall of the beaker needs to be dried when heated.
2. For dissolution, the amount of liquid does not exceed 1/3 of the volume, and it is necessary to stir with a glass rod. Do not touch the bottom of the cup and the wall of the cup while the glass rod is being stirred.
3. When used for liquid heating, do not exceed 2/3 of the beaker volume, generally 1/3 is suitable.
4. When heating corrosive drugs, cover the surface of the cup on the cup to prevent liquid spillage.
5. Do not use a beaker to hold chemicals for a long time to prevent dust from falling in, or evaporation of water.
6. Do not use a beaker to measure the liquid.The key to our success is “Good Products Good quality, Reasonable Value and Efficient Service” for factory Outlets for factory Outlets for China Glassware Transparent Cups 250ml Glass , We have now built a trustworthy track record amid many shoppers.
