CYLINDERS

Cylinders

Cylinders are essential instruments in any chemical, biological or industrial laboratory, as they allow volumes to be measured with high precision, which is crucial in experiments and processes where accuracy is paramount.

All cylinders have these common features: they are graduated cylinders, open at the top and supported by a hexagonal or circular base. Generally, they have a pouring spout to facilitate the pouring of the liquids contained, although they also exist with ground glass mouths to be able to close the test tubes with ground glass stoppers if necessary.

At Pobel, we specialise in the manufacture of high quality cylinders, designed to meet the needs of our most demanding customers. Whether you work in an academic environment, a pharmaceutical industry or any other field that requires accurate measurements, our test tubes are the ideal tool.

What are cylinders for?

Laboratory cylinders have multiple uses in different scientific and industrial areas. Some of their main uses include:

• Measuring liquid volumes: they are indispensable for accurately measuring different volumes of liquids.
• Preparation of solutions: used for mixing and preparing chemical solutions in specific concentrations.
• Chemical and biological experiments: used in a variety of experiments to measure reagents and products.
• Quality control: used in industries to verify and control the exact quantity of liquids in different production processes.
• Equipment calibration: used as a reference for calibrating other measuring equipment.
• Education and training: used in educational environments to teach students about accurate measurement and handling of liquids.
• Advanced research: essential in research laboratories where new products and technologies are being developed.

What material are Pobel cylinders made of?

Pobel cylinders are made of high quality materials to ensure durability and precision. The main materials used are:

• Borosilicate glass 3.3: this glass is resistant to thermal and chemical shocks, making it ideal for laboratory use. In addition, its clarity allows easy reading of graduations. Borosilicate glass 3.3 is known for its high resistance to sudden temperature changes, which is essential in experiments involving rapid heating and cooling. This material is also highly resistant to chemical corrosion, ensuring that the specimens maintain their structural integrity even when used with aggressive substances. In addition, borosilicate glass 3.3 is less prone to scratches and other physical damage, prolonging its lifetime and ensuring accurate measurements over time.
• Polypropylene (PP): This plastic is chemical and impact resistant, suitable for situations requiring greater physical resistance. Polypropylene is lightweight, making it easy to handle and reducing user fatigue during prolonged use in the laboratory. This material is also autoclavable, allowing it to be sterilised at high temperatures without compromising its structure, which is vital in environments requiring high standards of cleanliness and disinfecti

Manufacturing process and quality control

At Pobel, each cylinder goes through a rigorous manufacturing and quality control process to ensure that they meet the highest standards. Our process includes:

• Material selection: we use only high quality borosilicate glass 3.3 and polypropylene.
• Precise manufacturing: we use advanced technologies to manufacture lab test tubes with accurate and durable graduations.
• Quality control: Each batch of test tubes is rigorously tested for accuracy and strength.
