MEASURING PIPETTES

Measuring Pipettes

Laboratory pipettes are essential instruments for measuring and transferring precise volumes of liquids. Their precision and versatility make them indispensable in scientific experiments, clinical analysis and industrial processes. With a wide range of applications, pipettes ensure that every measurement is accurate and reproducible, contributing to the reliability of laboratory results.

What are laboratory pipettes for? Uses

Laboratory pipettes have many different uses, including:

• Accurate measurement of liquids: they allow accurate volumes of solutions to be measured, essential to ensure reproducibility of experiments.
• Preparation of solutions: They assist in the preparation of solutions with specific concentrations, ensuring consistency in analytical results.
• Titrations: used to add reagents in a controlled manner during titrations, essential in the determination of unknown concentrations.
• Clinical analysis: essential in medical laboratories for precise sample handling, ensuring reliable and accurate results.
• Research and development: used in the creation and testing of new chemical products, enabling innovations and improvements in various scientific fields.

What material are Pobel pipettes made of?

Pobel pipettes are mainly made of borosilicate glass and soda glass. Borosilicate glass is known for its high chemical and thermal resistance, which makes it ideal for applications requiring durability and resistance to extreme conditions. On the other hand, soda glass is used for applications requiring precision in standard conditions. These materials ensure that Pobel pipettes are durable, accurate and suitable for a wide variety of laboratory applications. 

How to use laboratory pipettes?

Pipettes are calibrated for "pouring". The first step is to fill the pipette, you must ALWAYS use a pipettor or pi-pump to fill the pipette. Fill a maximum of 10 mm above the gauge or graduation line of the pipette. Then you should clean and dry the outer surface of the pipette. Hold the pipette at eye level and place the tip of the pipette on the wall of the container, which is slightly inclined. You should then discharge the excess until the meniscus reaches the gauging or graduation line. The second step is to empty the pipette. You should empty the pipette by placing the tip of the pipette on the wall of the container, which is inclined. Pay attention to empty the pipette completely (or up to the 2nd gauging or lower graduation line).

Types of laboratory pipettes from Pobel

Pobel offers a wide range of pipettes to suit the various needs of laboratories. The main types are listed below:

Class A graduated pipettes

Made of soda glass, these pipettes are calibrated to ISO 835 and feature amber graduations. They are ideal for accurate measurements of variable volumes and are commonly used in a variety of laboratory applications.

Class B graduated pipettes

These pipettes offer lower accuracy than class A pipettes, but are suitable for many laboratory applications where standard accuracy is required.

Graduated culture pipettes

Specially designed for cell culture and microbiology, these pipettes allow precise transfer of liquids in culture processes.
