What is a narrow-mouthed container used to transportheatvor store substances often used when a stopper is a requierd?
A narrow-mouthed container used to transport or store substances, often requiring a stopper, is called a flask. Flasks are commonly used in laboratories for holding liquids and can come in various forms, such as volumetric flasks or Erlenmeyer flasks. Their design allows for easy mixing and minimizes evaporation or contamination.
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.
Can a flask perform accurate measurements?
It depends on what flask and what the quality of it is. If there is a hole in the flask, then obviously, no measurements. Most of the time, flasks do NOT give the most accurate measurements. Although, they do give more accurate measurements than a human eyeball and flasks do have their strengths compared to other tools as well.
What do heat flasks do?
Heat flasks are used to store and transfer heat energy to another object or substance. They are commonly used in experiments and industrial processes where precise temperature control is needed. By adding or removing heat from the flask, you can control the temperature of the contents inside.
What are cornical flask use for?
Cornical flasks, commonly known as conical flasks or Erlenmeyer flasks, are used in laboratories for mixing, heating, and storing liquids. Their conical shape allows for easy swirling of contents without risk of spillage, making them ideal for experiments that require mixing of solutions. They are also often used in titration processes due to their narrow neck, which helps in controlling the addition of reagents. Additionally, the flat bottom provides stability on lab surfaces.
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.
Is xenon used in cryogenic chambers?
Not especially.
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 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
Where cryogenic valves are used?
Cryogenic valves facilitate the transfer of Liquified gas. Space industry, natural gas / petroleum, medical industry, chemicals.
Scientist who used S-shaped flasks?
Louis Pasteur
What are rings used for in the laboratory?
They are used to hold round bottomed flasks and similar items.
What is the uses of measuring cylinder filter flasks conical flasks round-bottomed flasks in the chemistry?

What is cryogenic freezer?
A cryogenic freezer is used to bring components inside the freezer down to cryogenic temperatures. Many cryogenic freezers are available for all sorts of applications. Cold boxes with added ln2 capabilities can refrigerate parts and then complete cryogenic processing cycles. Additionally, cryo freezers are available to freeze sex cells, stems cells, and more. Sometimes people are frozen after death, which is called cryonics. I have added a site below that has cryogenic freezers and processors available.
What is cryogenic heat treatment?
cryogenic metal treatment
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.
What are round bottom flasks?
Round-bottom flasks are used to contain chemical reactions run by chemists, especially for reflux set-ups and laboratory-scale synthesis.
