Tubes

Tubes

Tubes are used in laboratories for various reasons.
Full glass tubes find application as stirring rods. Hollow glass tubes can also be easily processed at low temperatures in the laboratory.
Even though they are the raw material of our blowing plant, many laboratories are able to use glass tubes for their own applications.

Glass tubes

Because of the ease with which it can be worked, glass softens even at temperatures that are not too high. A small flame is enough to split a tube to make different products.

Filled Glass Tubes

This type of material is also known as 'glass rod'.
In the laboratory it is used to mix corrosive substances that would be lethal with other materials.
In large companies, glass rod is also used for special flame work performed by specialised blowers.

Hollow Glass Tubes

This type of product, although it can almost be considered a raw material, has many fields of application.
Because of its shape and variety of sizes, the glass tube is also applied in design and furniture. It is purchased by architectural firms for projects where the tube is used as a dividing or decorative element.

Rubber Tubes

Rubber hoses also have many uses. The traditional rubber hose used for watering the garden is also used in the laboratory for transferring liquids.
This, however, only applies to transferring water without any other necessary conditions.
Special hoses are used especially for industrial applications.

Rubber hoses for high pressures

The material from which they are made is chosen according to the nature of the liquid to be transported.
Tygon hoses offer strong resistance to chemicals and have a longer life than other materials.

The pressure with which the liquid is fed into the pipe determines the thickness of the pipe part. The pressure with which it is operated increases if the route is long or directed towards an outlet at the top.
If the thickness of the hose is not adequate, there is a risk of damage or rupture of the hose itself.
The rubber hose is classified not only for the passage of liquids but also for the passage of gases, according to current legal regulations.

Rubber hoses for pumping liquids.

Pump Hoses

One of the important elements in the choice of a pump hose is the number of revolutions of the pump.
The difference in material results in different resistances to the successive compressions to which the hoses are subjected.
This also determines the life of the hose.
Another factor to consider is the percentage with which the pump closes and compresses a hose.
It has been shown that a compression greater than 25% of the maximum limit, significantly deteriorates the material. Other elements to consider are the operating temperature and the density of the fluid.
In the Colaver catalogue, however, there are many different types of hose for every need.

To complement the pumps, accessories such as flow detectors are also on sale.
There are ball or turbine models on the market. These detectors are able to measure the flow and flow rate of the pump with a high degree of accuracy.
