What is the purpose of a flat-bottomed flask vs a cone - bottom flask

Choosing laboratory equipment should be approached responsibly. It is difficult to decide when it comes to the choice of flasks, because it is not enough to consider only the price-quality ratio of the goods. It is important that the dishes meet the following requirements:

  • safety;
  • durability;
  • accuracy.

To choose the perfect option, take into account the given parameters for specific studies. In doing so, pay attention to the specific properties of the products to determine the quality of the laboratory glass. If you are choosing between a flat-bottomed flask and a cone - bottomed flask, it is worth understanding the difference between them.

What is, a flat-bottomed flask

The flat-bottom vessel is a multipurpose vessel suitable for various laboratory operations. This flask can serve as a miniature apparatus for distillation and distillation processes. Thanks to its characteristic shape, it is stable, which allows it to be used without the use of any specialized stands.

A remarkable feature of flat-bottom flasks is their stability, which makes them ideal for placement on tables, on stirring platforms such as shakers. They do not require any additional support and are resistant to even small shock loads. These vessels are durable and have a significant surface area to interact with the environment.

The other benefits of this flask include:

  • Environmental friendliness;
  • Versatile application;
  • Resistance to high temperatures;
  • Compact size and low weight.

This flask is suitable not only for professional use, but also for domestic use, in design, florists, etc.

What is cone bottom flask

A cone bottom flask is a type of laboratory glass, which is mainly used for analytical tasks, titrations, as well as in the processes of recrystallization of organic substances from volatile solvents. It acts as a receiver for distillation. The shape of the conical flask is characterized by an angular taper of 1:16 and has several varieties: metric conical, inch conical and tubular conical. The first two types are designed to ensure the tightness of threaded connections, ensure their reliable fastening, and at the same time eliminate the need to use additional materials.

When to use flat-bottomed flasks

In general, if you have already decided on your choice, flat-bottomed flasks can be a universal solution. Such dishes are used for heating various solutions, as well as a receiver during distillation for various organic syntheses and analytical works. But if you perform different types of work, it is better to have numerous types of flasks at once.
