Substitute: a shallow clear glass or plastic container which covers your beaker.
But the main reason is as Dadface says, the economy of scale. Smaller market, smaller production volumes, higher prices. Anything that goes into a lab ends up costing a bundle.
You don't need to get rid of the used beakers, you could clean them and use them for something else, like putting plants in them or using them as pencil cups or whatever. Just don't drink out of them.
Data:
| Mass, Empty 50mL beaker | Mass, Beaker and 10.00mL and water |
|---|
| Run 1 | 28.27g | 38.07g |
| Run 2 | 28.29g | 38.24g |
Accordingly, how much does a 500 ml beaker weigh? Physics. A 500-mL beaker has a mass of
250 g when empty and
645 g when filled with an unknown liquid.

400ml Borosilicate Glass Beaker with Handle - Microwave Safe - Excellent for Use in the Lab, or as a Novelty Coffee Mug.
Although most types of beakers are made of glass, plastic beakers are also available.
- Erlenmeyer Flasks.
- Round Bottom Flasks.
- Volumetric Flasks.
- Filtering Flasks.
- Distillation Flasks.
Tell-tale signs of the beaker, of course, are the cylindrical glass, usually made of borosilicate, the flat bottom, the lip or beaded rim and the small spout, in the form of a beak. But interestingly enough, the beaker was likely named after the Beaker people who were master pottery makers during the Neolithic period.
Used in titrations to measure precisely how much liquid has been delivered. burette clamp. Used to hold burettes on a ring stand. clay triangle.
Beakers are simple cylindrical shaped containers used to hold reagents or samples. Flasks are narrow-necked glass containers, typically conical or spherical, used in a laboratory to hold reagents or samples. Examples flasks include the Erlenmeyer flask, Florence flask, and Schlenk flask.
Centrifuge tubes look like miniature test tubes that have tapered tips. These can be made of the glass and plastic.
Round-bottom flasks are shaped like a tube emerging from the top of a sphere. The flasks are often long neck; sometimes they have the incision on the neck, which precisely defines the volume of flask. It is a flask with an approximately pear-shaped body and a long neck with a circumferential fill line.
When you put water in a beaker or test tube, you see a curved surface. With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. So the liquid "sticks" to the side of the container. A few liquids have a "backwards" meniscus.
Medical Definition of Erlenmeyer flask: a flat-bottomed conical flask whose shape allows the contents to be swirled without danger of spilling. Comments on Erlenmeyer flask.
A graduated cylinder, also known as measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape.
why was it important to cover each beaker with a piece of aluminum foil? Without knowing the context, it is difficult to answer your question. However, it can prevent foreign materials from contaminating the contents of the beaker.
Graduated Cylinders are designed from ASTM E 1272, Style 1, Class B standards. Glass graduated cylinders are available in three sizes, 500ml 1000ml, and 2000ml, in 5ml, 10ml and 20ml increments. Glass cylinders have white scales and are made from Borosilicate glass. They also have a solid base, and pour spout.
The volume of a liquid can be directly measured with specialized glassware, typically in units of milliliters (mL) or liters (L). In this lab, a beaker, two graduated cylinders and a burette will be used to measure liquid volumes, and their precision will be compared.
Some chemistry glassware, called volumetric glassware, is inscribed with markings to make measuring the volume of liquids easier. The pieces of volumetric glassware found in the chemistry laboratory are beakers, Erlenmeyer flasks, graduated cylinders, pipets, burets and volumetric flasks.
