Erlenmeyer Flask

Your flask?

Round Bottomed Flask

and a Thermos of lukewarm cocoa.

I've put tea in the thermos, Mother.

I'll get my flask.

They're in the white flask.

You should bring your own flask.

Carter, I'd better take that Thermos of cocoa with me.

Mr Bienstock, could I have my flask?

Obviously, we don't know if those thermos flasks are their own.

There's a thermos of orange juice... and some applesauce cake to go with it.

One bottle of cognac, one Thermos of coffee at 40 degrees centigrade, two hundred cigarettes.

After I've had a flask of vodka, even I begin to see witches.

A rotary evaporator consists of a round flask in a bath of hot water, and is designed to evaporate solvents. The flask is rotated and the solvent collects under a vacuum onto a condenser and drips into a condensate collecting flask. In this way solutions can be concentrated or purified. By attaching a vacuum pump, the air pressure and therefore the boiling point of the fluid can be decreased.

I took the precaution of filling the flask from the water breakers before the storm, just in case of emergency.

So, if we could have the lights down and have it as dark in here as possible, I have a flask that has bioluminescent plankton in it.

So what we're trying to do is do reactions not in one flask, but in tens of flasks, and connect them together, as you can see with this flow system, all these pipes.

A round bottomed flask is used for many reactions. Some can be connected to other items, as the frosting on the neck shows. With cork rings they can be placed on a table.

What you're looking at on this slide is just a person from my lab holding a flask of a liquid culture of a bacterium, a harmless beautiful bacterium that comes from the ocean, named Vibrio fischeri.

(b) Danilo Lozano was said to have been taken to a small stream, where with a towel they had stopped his mouth and nose, while they poured water from a flask until he had almost drowned

A reflux condenser subjects fluid to a process where a gas produced by heating is collected on the reflux condenser. The fluid is cooled until it condenses and runs back into the original fluid. Usually it is put on a round bottomed flask or several neck flasks.

Burets are used to titrate liquids. A buret is filled with a specific volume of a liquid, and placed beneath it is a container such as an Erlenmeyer flask. By opening the valve on the buret, the liquid in the container will then be titrated. High quality burets have a venting mechanism with which they can be very easily refilled with the exact volume for which the buret is calibrated.

One means of separating a mixture is to use distillation. In this setting, a distillation bridge acts as a conduit between the two pots. One pot contains the mixture to be separated, and through heating, a gas forms which is lead through the bridge. At the end of the bridge the gas phase is condensed and drips into a round flask. Typically, the bridge is cooled by return flow. Also, there is often a thermometer for controlling the temperature of the distillation bridge.
