Bunsen Burner
The Bunsen burner is a laboratory burner commonly used for heating, sterilizing, or burning substances.
Its main characteristics are as follows:
Components: It consists of a stable base, a gas inlet (with a control valve), a vertical tube (chimney), and a movable ferrule at the base of the tube that controls the air supply.
How it works: It mixes combustible gas (town gas, butane, propane) with air to produce an open flame. The ferrule regulates the air supply, thus influencing the intensity and temperature of the flame.
Types of Flames: By adjusting the air supply, different flames can be obtained, ranging from a cool, yellow flame (incomplete combustion) to a hot, blue, and almost invisible flame (complete combustion).
Temperature: The flame temperature can vary considerably depending on the air setting, reaching high temperatures (e.g., 750 to 1600°C).
Use: It is essential in chemistry and biology laboratories for various applications, including heating reagents, sterilizing instruments, and creating a sterile area for delicate manipulations such as mushroom cultivation.
Burette 10ml

- They are used to deliver a precise volume of liquid, particularly during chemical titrations.
- Capacity: 10 ml, with glass or PTFE stopcocks.
Burette 25ml
Laboratory burettes are glassware instruments used for the precise measurement of liquid volumes.
Here is some information for purchasing burettes:
- Burettes are graduated glass tubes made of borosilicate glass such as Pyrex, known for their resistance to thermal shock.
- They are used to deliver a precise volume of liquid, particularly during chemical titrations.

Burette Stand
The burette stand features the following:
Materials:
Made of high-quality aluminum alloy or plastic for the clamp, and metal (such as iron or aluminum) for the stem and base, providing durability and corrosion resistance.
Functionality:
Designed to securely hold burettes during laboratory titration experiments, particularly on a titration table.
Clamp Design:
The clamp is often a “butterfly” or “double” type, allowing two burettes to be held simultaneously. Its jaws have sufficient elasticity to hold the burettes securely without obscuring the graduations.
Stability:
The heavy base and sturdy stem ensure stability during laboratory manipulations.
Use:
Easy to use for securing and adjusting the position of burettes, making it an essential accessory for science laboratories, schools, and factories.
