FLAT BOTTOMED FLASK: What It Is For, Capacity, Use

Every good chemical professional needs a flat bottomed flask, you can buy it along with all the necessary instruments, you should keep in mind that there are several types of flask that are equally indispensable for your work.

🌡 What is a flat bottomed flask?

Jars are used in laboratory environments (including chemistry laboratories) for a variety of purposes. A flask can be used to measure the volume of samples and liquid solutions or heat, cool, dissolve, mix or boil fluid. The jars are usually glass or plastic and can come in a variety of shapes and sizes. Typically, a flask is wider in the base than on the neck, with an opening at the top. Flask
they can have rounded or flat bottoms.

A flat bottomed flask is used in configurations where the flask will be placed on a level surface, rather than a clamp or a bowl. On the other hand, a flask with a round bottom will sit in a container or be suspended on a surface with a clamp.

🔬 Uses of the flat bottomed flask

A flat bottomed flask is used in a chemistry laboratory for experiments involving the collection and measurement of liquids, mixing solutions and culture media. The design and construction of the flat bottomed flask allows it to stand alone on the laboratory bench. See here what the flat bottomed flask is for

🔹 Features of flat bottom flask

Flask flat-bottomed has a round shape at its bottom and also has a straight neck and alargado.

Se uses to heat substances and measure reactions.

For what general a gauze material is used to put a barrier between the heat and the flask to evaluate the reactions safely and is also used in bacteriological culture.

There is a difference between a flat bottomed flask and a round-bottomed one and is that the latter does not have the base to stand upright on the surface, he must be place one.

Although it is very good for heating substance, this does not acquire the uniform heat that in addition, this is another difference from round flasks.The flat bottomed flask are not as strong or durable as glass flasks round bottom. Despite this disadvantage, they have one feature to their please: do not have the sharp and vulnerable corners of an Erlenmeyer flask, for example.

🍀 Variations of the flat bottomed flask from other flasks

Erlenmeyer Flask

The Erlenmeyer flask is also it is known as a conical flask. It is an interestingly shaped flask, a cone body and a cylindrical neck, was created in 1860 by the German chemist Emil Erlenmeyer.

They are usually made of glass, but they can also be made of plastic and they can also be made depending on the volume that is required.

The mouth of an Erlenmeyer flask may have a type of lip that can stop with a piece of cotton wool, cork or rubber.

Thanks to the fact that the sides of the flask are narrow, you can mix the liquid inside it without any problem or worry about losing anything.

Measured flask

These flasks are instruments laboratory, calibrated to contain a precise amount of volume at a particular temperature. Volumetric flasks are used for dilutions and accurate preparations of standard solutions.

The necks of the flasks they are elongated and thin, with a ring to mark their graduation.
This mark indicates the volume of liquid it contains when filled to that point.

🍀 Beakers of precipitation

These glasses are available in many sizes and presentations, they are used to heat and mix any class of liquids to be subjected to studies.

DURAN® flat bottom flask with molded edge

The uniform wall thickness distribution makes these flasks ideal for heating applications. The flat base means that the flasks can be placed without a support ring. Flasks with a neck diameter of 65 mm or more have a reinforced rim.

⭐ Flat bottom flask care

  • Recommend that all glassware is washed before using it for the first time.
  • Before using any piece of glass, always take the time to examine carefully and make sure it is in good condition.
  • Do not use no glass material that is scratched, chipped, cracked or etched.
  • Defects such as these can seriously weaken the mechanical strength of the glass and cause it to break with use.
  • Never use excessive force to fit the rubber plugs into the neck of a piece of glass.
  • Always make sure to select the correct plug size.
  • Carry or lifting glass jars, glasses or large bottles, etc. by the neck or the tire can be very dangerous.
  • Always provide support from the base and the lados.
  • Al shake solutions in glass containers, avoid using stir bars with sharp ends that can scratch the glassware and weaken it.
  • Always heat the glassware gently and gradually to avoid sudden changes temperature changes that can cause the glass to break due to a shock heat.
  • Similarly, allow the hot glassware to cool down gradually and in a place away from currents frías.
  • If it is using a heating plate, make sure that the top plate is more larger than the base of the container to be heated.
  • If the base of the container protrudes from the top of the hob, they can be produced connection points that cause the base of the container to break.
  • In addition, never put cold glassware on a preheated hob. Always warm up the glassware to temperature ambiente.
  • Ii it is using a Bunsen burner, employ a mild flame and use a wire gauze with a ceramic center to diffuse the flame.
  • Never apply heat located directly to a piece of glass.

📌 Tips to reduce the danger when using glass flasks

  1.  Inspect the glassware looking for defects such as cracks, scratches, deep marks and engraving marks before using the vacuum apparatus
  2. Make sure that the containers are designed specifically for vacuum work. Consider use smaller flasks (less than 1 L), as it is less likely that exploit. Thin-walled or round-bottomed flasks larger than 1 L never they must be evacuated.
  3. Assembling the vacuum apparatus to avoid tension. Heavy appliances should be supported from below and also by the neck.
  4. Glue the glass vacuum apparatus to minimize projectiles due to implosion. Use a criss-cross pattern of filament tape and/or build an enclosure around the flask.
  5. Use a protection suitable when performing pressure and vacuum operations, such as a barrier of plexiglas.
  6. Know the chemistry of the contents of the flask.
  7. Do not shake, knock or leave drop a flask that is under vacuum pressure. Also, try to avoid exposing the flask to unnecessary vibrations of the equipment on the same bench, music strong, etc. The flask should be anchored in place with a ring holder and a clamp.
  8. Use low vacuum intensity.
  9. Before performing any action with the flask (remove the funnel/stopper, adjust the hoses), be sure to release the vacuum by disconnecting the hose at the end of the vacuum pump (as opposed to the end of the flask).
  10. Use protection for the eyes and face when handling vacuum or pressure appliances.

🔍 Volumetric flask

It has an elongated and narrow neck, with a capacity that marks where the flush should be carried out, which indicates a volume with great accuracy and precision.
