What laboratory tools is used for containing liquid substances?
Flasks and beakers are the most common containers of liquid in the laboratory. Some other tools used are vials, test tubes, and even simple bottles and jars.

Who is Paula Tennant?
Paula tenant is a Jamaican scientist who discovered the virus know as ringspot virus and found a cure the ringspot virus
What scientist used flasks to support the theory of biogenesis?
Louis pasteur was the one to support th theory of biogenesis.
Where are Pasteur's flasks?
Pasteur's flasks are glass containers used in laboratories for experiments and culturing microorganisms. They are named after the famous scientist Louis Pasteur, who used them in his groundbreaking work on microbiology and germ theory in the 19th century. Today, Pasteur's flasks can be found in scientific laboratories around the world for various research purposes.
Who was the scientist who used s shaped flasks?
Louis Pasteur is the scientist known for using the S-shaped flasks in his experiments on spontaneous generation. By curving the neck of the flask to prevent entry of airborne microbes while allowing the passage of air, Pasteur demonstrated the presence of microorganisms in the air and debunked the idea of spontaneous generation.
Who heated broth in sealed flasks?
Louis Pasteur was the scientist who demonstrated that microorganisms in broth could be killed by heat. He conducted experiments with sealed flasks to show that the growth of microorganisms did not occur when they were exposed to heat.
What are the uses of a flask?
The round bottoms on these types of flasks allow more uniform heating and/or boiling of liquid. Thus, round-bottom flasks are used in a variety of applications where the contents are heated or boiled. Round-bottom flasks are usually used in distillation by chemists as distilling flasks and receiving flasks for the distillate One-neck round-bottom flasks are used as the distilling flasks in rotary evaporators.This flask shape is also more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface.
Why are beakers and flasks not used for heating solids?
the heat may not be distributed uniformly if solids are heated in beakers or flasks
What scientist uses a Erlenmeyer flask?
Many scientists use Erlenmeyer flasks, but the most obvious users are chemists and biologists.
What is the purpose of a flask?
A flask is essentially a bottle. * In a labs, glass flasks (Erlenmeyer, Florence) are used for mixing heating and storing solutions. Sometimes they are graduated to show the volume of material that they contain.* Vacuum flasks are more robist, ususally with a side arm to remove gases * Insulated flasks keep things cold like liquid nitrogen
Who was the scientist who showed that microspic life is not produced by spontaneous generation?
Louis Pasteur is the scientist who demonstrated that microorganisms do not arise from spontaneous generation through his famous experiments with swan-necked flasks in the 19th century.
What is the uses of measuring cylinder filter flasks conical flasks round-bottomed flasks in the chemistry?
IS IS
What are rings used for in the laboratory?
They are used to hold round bottomed flasks and similar items.
Why are erlenmeyer flasks specifically used for recrystallization processes?
Erlenmeyer flasks are used for recrystallization processes because their conical shape allows for efficient mixing and evaporation of solvents, which helps in the formation of pure crystals.
