Shake Flask fermentation is a cheapest ans simplest technique to grow bacteria or fungi, aerobically, in small volumes of nutrient broth. The broth is poured into erlenmeyer flasks equipped with cotton-wool stoppers, and autoclaved. After cooling, some microbes are "seeded" into the flask, and it is placed on a Shaker machine. The shaking agitates the content and so ensures aeration, so that the microbes could breathe.
Shake flasks, such as the Erlenmeyer flask, are designed to prevent splashing. They promote oxygen transfer and prevent vibration, allowing for successful fermentation.
Rinse the volumetric flask twice with the solution that you about to fill it with, stopper the opening and shake the flask so that all surface area inside the flask will be covered. This is so that the solution will not be diluted or contaminated when poured into the flask.

measuring flask is a measuring flask
there are various types of flask used in lab such as round bottom flask, flat bottom flask, conical flask.
volumateric flask is also a type of flask
The Erlenmeyer flask is conical and the Florence flask is rounded.
The egg does not go into the flask when heated. When the flask is heated the air expands in volume and escapes around the egg. When the flask is removed from the heat, the air in the flask cools, leaving low pressure in the flask which then draws the egg into the flask.
Flask, being a noun, does not have an antonym.
Louis broiled broth for 15 min. He then let it sit for one year in a swan neck flask. He noticed that some dust had accumulated in the top part of the flask. So he took a sample, form the broth inside the flask. He noticed that nothing was inside of growing in it. So he then preceded to shake the broth in the flask in such a way, that it would touch the dust at the top. He then took a sample from that and it was highly bacteria ridden.

Lactic acid fermentation and alcoholic fermentation.
A florence flask is a round bottomed flask used for boiling.
They are the same thing, a thermos flask is just a different name for it. A vacuum flask is the original name.
Because this flask has a conical form ! Another name is Erlenmeyer flask. See the link below.
The iodine flask is an Erlenmeyer flask with a stopper; it is used for the iodine determinastion.
The Erlenmeyer flask is conical, the Florence is rounded.
The correct spelling is conical flask. A conical flask is a type of flask that is used in laboratories. They have a conical body, flat bottom, and cylindrical neck.
Acholic fermentation lactic acid fermentation wine fermentation
The flat bottomed flask used by chemists is called an Ehrlemeyer flask.
