Types of Chemistry Flasks

Types of Chemistry FlasksThere are actually a number of different types of chemistry flasks. Some are called punch down flasks, punch up flasks, pressurized flasks, and even acid-proof flasks. Which one you will want depends on what you are studying. If you are studying chemicals, then you will want to purchase a punch down flask that will be easily transferred from its container to your lab.A punch down flask is basically a short cylinder that is filled with powdered liquids. Once it is full, the stopper at the top of the cylinder is attached. When there is an increase in temperature, the stopper drops and the liquid inside the cylinder become liquid and then turn into gas when heated. The name comes from the fact that the stopper has to be punched down in order to let the liquid inside become liquid and then turn into gas. The amount of liquid it can hold depends on how hot it gets when the stopper falls.The Punch Down Flask is one of the most common types of flask. It can be fille d with organic solvents, a wide variety of chemicals, and other materials that can be used to create solutions for experiments. This flask is very easy to handle and carry, so you do not have to worry about spilling something inside. Other kinds of flasks like the pressurized flask are more for pure water solvents and chemicals, but they are also easier to handle and transport. The high pressure inside the flask can cause extreme heat and you can easily transfer it from the container to your lab.The Punch Up Flasks are used with water solvents, which can be toxic to some students. They are also used with chemicals that are harmful to the lungs and others that can cause skin allergies or chemical burns. The high pressures make them dangerous as well. These types of flasks are sometimes referred to as respiratory hazard flasks or chemical hazards flasks.Pressurized flasks are ideal for testing chemicals or materials that are a little too high to handle by hand. Most of these types of flasks are made of stainless steel, although other materials can be used as well. There are two types of flasks that have this style of opening. The first is called the flameless dispenser, and the second is called the flame top.If you want to get the right amount of oxygen into your hot work area, a flame-top flask is the way to go. Since it is open, there is always a flow of oxygen coming out and through the flask. It is not meant to be used by children. Most of these flasks come with air holes on the lid and an air filter.Oxygen bottles are another popular type of flask that most students use when doing experiments that will require a lot of oxygen. They can be used to test chemicals, which must have a certain level of oxygen in order to be safe for the experiment. You can also get a good deal of research done using flasks with oxygen that will contain some material that can be used to test things. Since a lot of research is now done in a lab environment, it makes sense to use a flask with oxygen instead of using a chemical to see if it can actually make something work.Lastly, some students may find that it is easier to use a type of flask called a non alcoholic gas. These types of flasks are nonvolatile and are usually used with nitrogen gases.
