Eppendorf tubes are extremely important tools in laboratories, playing a key role in storing, transporting and maVATulating small sample volumes. They are widely used in the fields of molecular biology, biochemistry and cell culture. In this article, you'll learn everything you need to know about Eppendorf test tubes, from their history and uses to their advantages and disadvantages.

What are Eppendorf Tubes?

History

Eppendorf tubes were first introduced to the market by Eppendorf AG in the 60s. Since then, they have become an indispensable tool in laboratories around the world. Their invention was driven by the need to store and maVATulate small volumes of samples safely and efficiently.

Purpose and application

Eppendorfs are mainly used to store samples in small volumes, most often ranging from a few microliters to several hundred microliters. Their precise scaling allows for accurate measurement and transfer of fluids, which is extremely important in laboratory experiments.

Types and sizes

Eppendorf test tubes come in various types and sizes, depending on specific laboratory needs. The most common tubes are 0,2 ml, 0,5 ml, 1,5 ml and 2 ml. In addition, there are also specialized versions, such as test tubes resistant to low temperatures or those for use in PCR reactions.

Features

Material and design

Eppendorfs are usually made of high-quality plastics such as polypropylene. This material is not only transparent, allowing easy sample visualization, but also resistant to many chemicals, ensuring safe sample storage.

Graduations and markings

Many eppendorfs are equipped with precise scales, enabling accurate reading of sample volumes. This is especially important when precision is crucial in a given application, for example in the preparation of solutions or enzymatic reactions.

Types of plugs and tightness

They are equipped with various types of plugs to ensure tight closure and protection against possible leaks. Some caps also have special mechanisms that prevent the tube from being accidentally opened during storage or transportation.

RECOMMENDED USE

Molecular Biology

Test tubes are indispensable in the field of molecular biology, where you often work with small volumes of reagents and biological samples. They are used to store and perform enzymatic reactions, DNA amplification using PCR, and to analyze genetic sequences.

Biochemistry

In biochemistry, Eppendorf tubes are used in various stages of experiments, such as preparing and storing solutions, studying the kinetics of enzymatic reactions or analyzing the structure of proteins.

Cell Culture

In cell culture, eppendorfs are used to prepare and store culture media, perform transfections, or collect cell samples for microscopic analysis.

Innovations in Eppendorf test tubes

Improved materials and design

Eppendorf AG constantly innovates to improve test tube performance and quality. Modern test tubes are made of more advanced materials, which translates into greater resistance to damage and better barrier properties.

Specialized Eppendorf test tubes

In addition to standard versions, specialized test tubes are also available, such as those for long-term storage at low temperatures, test tubes optimized for specific reactions, or those dedicated to automatic laboratory systems.

Comparison with other types of test tubes

Eppendorf tubes vs. Falcon tubes

Both Eppendorf tubes and Falcon tubes are popular tools in laboratories. Both have their advantages and applications. Eppendorf tubes are more suitable for small sample volumes, while Falcon tubes are more capacious and used for storing larger volumes.

Eppendorf tubes and microcentrifuges

Eppendorfs are often used in combination with microcentrifuges, which allow the separation of substances with different molecular weights. Microcentrifuges are an essential tool in analysis and research in biological and chemical laboratories.
