The types of flasks: features, purpose

Laboratory glassware is characterised by diversity. It is used in the process of testing in various fields. A huge number of variations presented of capacities allows you to apply in each specific case the most appropriate variety.

The Existing Types of bongs can be classified according to certain characteristics. This allows you to delve deeper into their application and significance to the analysis. Varieties of laboratory glassware deserve special attention.

General characteristics

In vitro studies often used a Glass jars. They allow many different operations and chemical reactions. Big enough article of expenses of any of the laboratory is the container.

As most flasks are made of glass, they can chip. Today there are a variety of Types of flasks. They can be exposed to temperatures or chemicals. Therefore, the material of which is made a Petri dish, must be able to withstand such loads.

Configuration of the tubes can be very unusual. It is necessary to conduct a full chemical experiments, and analysis of the substances required. Most often, such containers have a wide base and a narrow throat. Some of them can be equipped with a stopper.

Varieties of forms

In laboratory studies can be used flat-bottomed, and Round-bottom flask. This is the most commonly used types of containers. Flat-bottomed varieties can be put on a flat surface. Their purpose is very diverse.

Round bottom flasks hold a tripod. It is very convenient if the container is required to be heated. For some reactions it speeds up the process. Therefore, round-bottomed flask is most often made through this application features heat resistant glass.

The Use of bulbs and their configuration

Types of flasks and their names is very diverse. They depend on the application. The Kjeldahl flask is characterized by a pear shape. It is most often used in the same apparatus for the determination of nitrogen. This bulb may have a glass stopper.

For the distillation of various substances used bulb burza. In its structure there is breather pipe.

Claisen Flask has two necks, the diameter of which is same along the entire length. One of them is fed by tube, are designed to exhaust steam. The other end reports the utensils with refrigerator. This variety is used for distillation and distillation under normal pressure.

The Flask Bunsen is used in the filtering process. Its walls are very durable and thick. At the top there is a special process. He comes up to the line vacuum. For experiments under reduced pressure, this kind is ideal.

Erlenmeyer flasks

Considering the existing Views Kolb, it is impossible not to pay attention to another form of lab glassware. The name of this capacity, given in honor of its Creator-a German chemist Erlenmeyer. This is a conical container that has a flat bottom. Her neck is characterized by a cylindrical shape.

This bulb has a division that allow us to determine the volume inside the liquid. A unique feature of this kind of packaging is the insertion of special glass. This kind of notebook. Her chemist can make the necessary notes.

The Neck if necessary, you can close the cap. The conical shape ensures high-quality mixing of the contents. Narrow neck prevents spilling of the substance. The evaporation process in such containers is slower.

The Flask is presented of the type used in the titration, the cultivation of pure cultures or by heating. If the bulb has a division in the body, they are not heated. This cookware allows you to measure the amount content of a substance.

Some features

Used types of bulbs can also be divided into groups depending on the type of filler neck. They are simple (under the rubber plug), as well as with cylindrical or conical ground joint.

Depending on the type of material from which made dishes, it can be heat-resistant or normal. The purpose of the bulb can be divided into measuring cups, receivers and reactors.

Volume laboratory glassware is also quite diverse. Their capacity may range from 100 ml to 10 l. flask are even larger. When working with such containers it is necessary to observe safety rules. Each variety of the presented products should be applied strictly for its intended purpose. Otherwise you can break the bulb or cause harm to your body.
