TEST TUBES

Laboratory Test Tubes

Laboratory test tubes are essential tools in any scientific setting, whether in chemistry, biology, medicine, or research laboratories. Designed to hold small amounts of liquid, these tubes are critical for performing accurate experiments and analysis. In addition to holding liquids, they allow for direct observation of biological reactions and processes under various experimental conditions. At Pobel, we offer a variety of high-quality test tubes, made from durable materials and tailored to the specific needs of each customer.

What are test tubes?

Test tubes are cylindrical glass or plastic containers, primarily used in laboratories to hold, mix, or heat small amounts of chemicals. Their design includes a rounded or flat bottom and a narrow top opening, making them easy to handle and pour liquids into. These tubes are transparent, allowing for direct observation of the reactions occurring inside.

What are laboratory test tubes used for? Applications

Pobel test tubes have multiple applications in various scientific and industrial fields:

Chemical analysis: used to mix and react small amounts of reagents.

Cultivation of microorganisms: ideal for the growth and observation of bacteria and fungi.

Heat tests: suitable for heating substances to different temperatures.

Temporary storage: used to contain liquid or solid samples for short periods.

Decanting: allow separation of immiscible liquids.

Observation of reactions: used to visualize color changes and precipitates in chemical reactions.

What material are Pobel test tubes made of?

Pobel test tubes are made from two main types of materials, each with its own advantages:

Borosilicate glass: This type of glass is known for its high resistance to thermal and chemical shocks. It is ideal for applications that require direct heating and sudden changes in temperature. Borosilicate glass is also highly transparent, making it easy to observe chemical reactions. Its resistance to sudden temperature changes ensures that the test tubes maintain their structural integrity even under extreme conditions. Borosilicate 3.3 glass is also highly resistant to chemical corrosion, which prolongs its life and maintains its accuracy over time.

Polypropylene (PP): This plastic material is resistant to chemicals and impacts, suitable for situations requiring greater physical strength. Polypropylene is lightweight, making it easy to handle and reducing user fatigue during prolonged use. In addition, it is autoclavable, allowing it to be sterilized at high temperatures without compromising its structure. This material is resistant to deformation under mechanical stress, ensuring that the test tubes maintain their shape and functionality even after repeated use under demanding conditions.
