Types of Burettes

What Are Burettes and Why Are They Essential in the Laboratory?

Burettes are glass or plastic instruments used in chemical and biological laboratories to measure precise volumes of liquids. Their design includes a graduated tube with a stopcock at the bottom, allowing precise control of liquid flow.

They are essential in processes like titrations, where accuracy in solution dosing is crucial to obtaining reliable results. The versatility and precision of burettes make them indispensable tools in chemical experiments, quantitative analyses, and industrial processes.

Main Types of Laboratory Burettes

At Pobel, we offer a wide variety of burettes to meet the different needs of laboratories. Below, we present the main categories:

Straight or mohr burettes

Straight burettes, also known as Mohr burettes, are graduated glass instruments essential in laboratories requiring high precision in liquid measurement and dispensing. They are ideal for titrations and delicate experiments in academic, professional, and industrial environments.

Main Features

• Precise graduation: clearly defined scales for exact measurements.
• Durable material: made of borosilicate glass, resistant to chemicals and temperature changes.
• Flow control: equipped with stopcocks for precise, leak-free regulation.
• Functional design: practical, ergonomic, and easy to clean.

Burettes with reservoirs

Burettes with reservoirs are laboratory instruments designed to measure and dispense liquids with high precision. They feature an integrated upper reservoir that allows continuous flow and eliminates the need for frequent refills. These are ideal for chemical analysis, academic research, and industrial processes demanding precision and consistency in results.

Main Features

• Integrated reservoir: allows continuous liquid dispensing, optimizing autonomy.
• Precise control: equipped with precision stopcocks or valves to regulate flow.
• Durable material: made of borosilicate glass or specialized plastics for high durability and chemical resistance.

Burettes automatic zero

Burettes automatic zero are laboratory instruments designed for precise liquid measurement and dispensing. They incorporate a fixed base or stand that ensures stability and comfort. These eliminate the need for additional clamps and provide safe and efficient handling during prolonged experiments, such as titrations. Their ergonomic design and stopcock system facilitate exact control of liquid flow, optimizing precision in every use.

Schilling burettes

Schilling burettes are high-precision instruments designed for laboratories requiring accuracy and control in liquid measurement. They stand out for their innovative design, which includes an integrated upper reservoir and an advanced flow control system, ideal for prolonged experiments and industrial applications.

Unlike traditional burettes, Schilling burettes allow a constant, uniform flow without the need for frequent refills, thanks to their additional reservoir. This design enhances efficiency and precision in complex experiments, reducing interruptions and ensuring reliable results.

Frequently Asked Questions About Burettes

How Many Types of Burettes Are There?

There are several types of burettes, including straight burettes or Mohr burettes, burettes with reservoirs, burettes automatic zero, and Schilling burettes.

How Do You Read a Burette?

To correctly read a burette, position your eye level with the meniscus (the curve formed by the liquid). Record the value corresponding to the bottom of the meniscus.

What Does Priming a Burette Mean?

Priming a burette involves filling the bottom of the tube and the stopcock with the solution before starting a titration. This prevents measurement errors caused by air bubbles.
