What is a circular beaker called?
Round-bottom flasks (also called round-bottomed flasks or RB flasks) are types of flasks having spherical bottoms used as laboratory glassware, mostly for chemical or biochemical work.
What is the difference between beaker and test tube?
Basic Glassware Test tubes are the archetypal image of chemistry, whilst beakers also make frequent appearances in school practicals. Boiling tubes aren’t that different from test tubes in appearance, but are used when heating is required – they tend to be made of thicker glass, and are slightly larger and wider.
What can I use instead of Beaker?
watch glass. Substitute: a shallow clear glass or plastic container which covers your beaker. This is used to collect vapors when heating liquids.
What are the different types of test tubes?
Test Tube Types
| Blood Tubes | Abbreviation |
|---|---|
| Light Blue-top Tube | (CI) |
| Red-top tube | (SE) |
| Royal Blue-top tube | (O) |
| Royal Blue-top, EDTA | (O) |
Why beaker is called beaker?
Along with things like Bunsen burners and test tubes, a well-stocked chemistry lab has plenty of beakers. The word comes from the Greek root bikos, “earthenware jug.” Definitions of beaker.
What is the difference between flask and beaker?
Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next.
What is a beaker?
A beaker is a glass container with a flat bottom that scientists use to hold liquids. In Britain, a beaker is a drinking cup mainly used by children, but in the U.S. the word is primarily used to mean a cylindrical glass vessel for mixing, measuring, and pouring liquid chemicals.
Are flasks and beakers the same?
What is use of beaker?
Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Laboratory Burners are sources of heat. Burets are for addition of a precise volume of liquid.
What does beaker look like?

What is an example of a beaker?
A wide cylindrical glass vessel with a pouring lip, used as a laboratory container and mixing jar. The contents or capacity of a beaker. A wide, cylindrical glass container with a pouring lip, used especially in laboratories. A flat-bottomed vessel, with a lip, used as a laboratory container.
What is example of beaker?
What do you use a beaker for in chemistry?
A beaker is a key piece of chemistry glassware. Science Photo Library / Getty Images. Beakers are the workhorse glassware of any chemistry lab. They come in a variety of sizes and are used for measuring volumes of liquid.
How much liquid does a 250 mL beaker hold?
Some aren’t even marked with volume measurements. A typical beaker is accurate within about 10 percent. In other words, a 250-ml beaker will hold 250 ml +/- 25 ml of liquid. A liter beaker will be accurate to within about 100 ml of liquid.
Why is the bottom of a beaker so flat?
The flat bottom of a beaker makes it easy to place on flat surfaces such as a lab bench or a hot plate. The spout makes it easy to pour liquids into other containers. Finally, the wide opening makes it easy to add materials to the beaker. For this reason, beakers are often used for mixing and transferring liquids.
Which is better a beaker or an Erlenmeyer flask?
For some situations, either a beaker or an Erlenmeyer flask is a good choice, but if you need to seal a container, it’s much easier to put a stopper in an Erlenmeyer flask or cover it with parafilm than it is to cover a beaker. Erlenmeyer flasks come in multiple sizes.
