What is the white square on a beaker?
The square plate design allows you flexibility of vessel sizes and combinations. Up to four 250-mL beakers can easily fit on the surface at the same time.
What are glasswares used for?
Glassware used as laboratory apparatus offers a wide range of containment and transport functions for solutions and other liquids used in laboratories.
What are the dos when handling laboratory glassware?
Do Handle Glassware Safely Eliminate potentially dangerous chemical reactions by thoroughly washing beakers, test tubes, flasks and other glassware before and after use. This also helps ensure that results are not tainted by chemical residue from previous experiments.
What is the piece of lab equipment used to scrap out the bottom of Erlenmeyer flasks?
Scoopula is a brand name of a spatula-like scoop utensil used primarily in experimental laboratories to transfer solids: to a weighing paper for weighing, to a cover slip to measure melting point, or a graduated cylinder, or to a watch glass from a flask or beaker through scraping.
What is beaker in laboratory?
Laboratory beakers are vessels in which liquid is placed so it can be stirred, mixed or heated. They come in a variety of shapes, sizes and materials depending on the application, and can be reusable or disposable.
What is a clay triangle?
Clay triangle A triangular device made of heat-resistent clay. Used to hold crucibles and porcelain dishes heated by a Bunsen burner. Distributes heat evenly over the surface of objects it holds.
How do you read lab glassware?
All volumetric glassware is calibrated with markings used to determine a specific volume of liquid to varying degrees of accuracy. To read this volume exactly, the bottom of the curved surface of the liquid, the meniscus, should be located at the scribed line for the desired volume.
What are the basic ground rules for using laboratory glassware?
With proper precautions, work with glassware can be conducted safely.
- When handling cool flasks, grasp the neck with one hand and support the bottom with the other hand.
- Lift cool beakers by grasping the sides just below the rim.
- Never carry bottles by their necks.
- Use a cart to transport large bottles of dense liquid.
What precautions should be taken in chemistry lab?

- Know emergency exit routes.
- Avoid skin and eye contact with all chemicals.
- Minimize all chemical exposures.
- No horseplay will be tolerated.
- Assume that all chemicals of unknown toxicity are highly toxic.

What type of glassware should I use for my lab sample?
Glass Bottles and containers provide the best sample integrity. Glass is inert and thus more chemically compatible than plastic, so the only concern about the chemical resistance of lab glassware is the type of liner inside the cap.
What is the use of labware in lab?
Lab glassware are the essential parts of most experimental labs like chemistry, biochemistry, biology, genetics. There are a number of lab ware for use made of different material. But glassware are more common due to time tested use and suitable for almost all the experiments. Lab ware made of glass are preferred due to many advantages like
