A borosilicate glass Erlenmeyer flask has several key characteristics:

Materials:
It is made of borosilicate 3.3 glass (such as Pyrex™ or Duran®), known for its high resistance to thermal shock and chemical corrosion.

Capacity:
The flask pictured has a capacity of 250 ml, with graduations indicating volumes (100,150, 200, 250ml).

Shape:
Its conical shape ensures good stability and facilitates mixing and heating liquids. The neck can be narrow or wide.

Graduations:
It has graduations (often white enamel) for approximate volume measurements.

Resistance:
Borosilicate glass provides excellent heat resistance, allowing direct heating and autoclaving for sterilization.

Use:
It is commonly used in laboratories for mixing, heating, cooling, and storing liquids, as well as for titrations and cell cultures.

The characteristics of a test tube like the one pictured include the following:

Materials:
Clear glass (such as soda-lime glass or borosilicate).

Shape:
A narrow cylindrical body with a base that can be round (U-shaped), conical (V-shaped), or flat, and a top opening. The image shows a flat bottom.

Dimensions and Capacity:
Test tubes come in various sizes and volumes. The one pictured is graduated up to 10 ml, with an accuracy indication of “±0.2”. The visible graduations are 1, 2, 4, 6, 8and 10ml.

Use:
Used in laboratories to hold, mix, and heat chemicals, or for specific analyses such as food quality control or blood tests. The object in the image, being graduated, is more specifically a flask, used to precisely measure liquid volumes.

Resistance:
Resistance to temperature changes and chemicals varies depending on the type of glass

A graduated cylinder is a laboratory instrument used to accurately measure liquid volumes. Its main characteristics are as follows:

Materials:
This is a graduated cylinder made of borosilicate glass, known for its resistance to chemicals and thermal shock.

Shape and Structure:
It has an elongated cylindrical shape and is equipped with a stable base (here, a round base, although hexagonal bases also exist) and a pouring spout to facilitate the transfer of liquids.

Graduations:
The cylinder is clearly graduated, allowing the volume of liquid contained to be read. In the image, the graduations are visible from 100 ml to 500 ml, indicating a maximum capacity.

Accuracy:
Graduated cylinders are designed for precise volume measurement, often calibrated “to contain” (TC or In) and classified according to accuracy standards (such as Class ).
