The Fisher burner: Find what you're looking for here!

In this article you will find all the information about the Fisher burner, which is one of the lighters that provides great help in the laboratory and is one of the most used in the physicochemical analyzes required for it. So keep reading the article so that you know everything about this interesting instrument.

What is a Fisher burner?

The Fisher burner is an instrument laboratory equipment that is used to create fire from the gas mixture fuel and oxygen in certain proportions, the applications of which are to heat and sterilize materials or reagents (liquid, gaseous and solid).

This lighter is composed of a vertical pipe, the base of which connects to the gas inlet. Their way of regulating the flame of the fire which are through the key which connects to the gas, or by
holes that allow oxygen to enter the lighter, which consists of a ring that allows the passage of oxygen.

In the following figure you can see the Fisher burner:

✔ What is the Fisher burner for?

This lighter is used to heat materials or substances (liquid, solid or gaseous) in order to perform a physicochemical analysis.

It is commonly used for sterilization, which consists in the removal of microbial agents from the surface of materials by means of the flame, which should only be approached to the object at sterilize for a few minutes. For this process the Fisher burner is the most suitable.

It is also used for cultivation microbiological (widely used in biology and medicine), which seeks to increase the content of bacteria (causing them to multiply) in order to study them, for which culture media must be prepared by means of the burner.

➤ Characteristic

The main features of this lighter are:

Its temperature ranges from (1100-1200)°C

This helps the materials and substances to be used in the corresponding analysis to be heated to high temperatures.

It has an open and wide flame

The width of the flame produced by this lighter is ideal to increase the heating surface for whatever you want to expose to the flame.

The burner employs a material made of chromed brass

Such material is perfect because it is resistant to corrosion, so it is very durable for use.

It has a valve that regulates the gas and air inlet

These help to allow the gas and the ambient air to combine so that the combustion reaction is obtained and in that way the flame that will be used for heating is produced.

It has a grid with holes at the end of the burner

This allows the flame to be obtained to be uniform and without cuts where it has the same temperature on each side, so there is no problem on the side of the flame to be heated.

It has a flame arrester at its upper end

Which makes it easier for the flame not
i veered off to another site and prevented the recoil from it, so it
keeps in position and prevents possible incidents.

✔ Types of Fisher burner

Actually this lighter does not have a classification, but rather it is a type of lighter that is commonly used for heating of containers in the sterilization process or of crops microbiological.

However, there are other types of cigarette lighter such as: The bunsen lighter and the Feclu lighter.

Difference of the Fisher burner with other lighters

There is not much difference between the Fisher burner and the others lighters (Bunsen and Feclu), as all three produce the same flame, only it is the way they produce it. Since the Fisher burner produces a wide flame and open, but the bunsen burner produces a normal flame not very uniform and not so wide.

The Feclu lighter has a cone-shaped lower part, it produces a flame a little more efficient than that of the bunsen lighter, but not as much as that of the Fisher burner since this, due to its size, achieves a wider flame and generates high temperatures.

➤ Fisher burner parts

This lighter consists of the following parts:

Fireplace

Said part consists of a lid that has an approximate of 50 to 100 holes that generates a correct uniformity to the flame that is produced, which helps to obtain a homogeneous heating.

Body

The body of the lighter is usually made of chrome-plated brass, and its base is made of zinc and aluminum, allowing it not to be affected by corrosion or chemical substances that may cause damage to the material.

Regulating valve

This serves to control the gas flow, thereby allowing a manipulation of the size and width of the flame that is produced.

Gas inlet

The aforementioned inlet serves to open the inlet of the gas or fuel used to obtain the flame, which are usually the most used: propane and butane.

Oxygen intake

This is used to allow oxygen from the air to enter the burner to combine with the gas so that the combustion reaction occurs, resulting in the generation of the flame.

Flame Arrester or Flame Arrestor

It serves to prevent the flame from
step back so that some accident does not happen to be regretted within the
laboratory.

✔ Fisher burner usage methodology

Initially it should be checked that the gas and oxygen inlets are closed, for this it can be noticed if the gas valve is in the direction of flow which would indicate that this is it is open, so it must be closed at the beginning. For oxygen intake, this is a ring that is at the top base of the lighter, so it should be turn right to close it.

Once it has been verified that the air and gas inlets are closed, we proceed to open the oxygen one by turning the ring to the left, then the main gas valve is opened and the one located at the bottom of the lighter by turning it to the left. The latter is manipulated in such a way that the blue flame (complete combustion) is obtained. The material to be heated is placed, and once the necessary heating has been completed, then the gas key is first closed, then the one at the bottom of the burner and finally the air inlet is closed.

➤ Fisher burner Price

When consulting with various suppliers of laboratory instruments, it was possible to specify that the price of the Fisher burner is on average 650$. Such a price is not very affordable, however, this is an instrument whose service life is long, it resists high temperatures, so what would be ideal to invest in it.

✎ Importance of the Fisher wick

Said lighter is a very important instrument, because it intervenes in the sterilization of materials by exposing them to high temperatures where microbial agents such as bacteria, microbes, among others, are eliminated. Being very relevant since, if this were not done, said materials would be exposed to the aforementioned agents so it would cause contamination, causing problems at the microbiological level.

In conclusion, the lighter Fisher is a laboratory instrument that is used to generate high temperatures through the combustion reaction produced by the mixture of fuel (usually propane or butane) with oxygen from the air, obtaining a wide, open flame whose temperature ranges from 1100 to 1200°C. This flame it is commonly used for the sterilization of materials and also for the preparation of laboratory culture media.
