Microcentrifuge Tube

Microcentrifuge tube is a kind of small centrifuge tube, also known as EP (eppendorf) tube, which are normally used with microcentrifuges for separating and centrifuging micro reagents.

What are the differences between the micro centrifuge tube and regular centrifuge tube?

For volume, micro centrifuge tubes are generally smaller in capacity and are suitable for centrifugation of small sample volumes, such as typical eppendorf 1.5 ml safe lock tubes, 2 ml microcentrifuge tubes, 5 ml microcentrifuge tubes. On the other hand, normal centrifuge tubes have a relatively large capacity and are suitable for handling larger samples.

For material, micro centrifuge tube is usually made of high-quality plastic materials, such as PP, with good chemical stability and corrosion resistance, which ensures that the samples will not be contaminated during processing. In contrast, normal centrifuge tubes may be made of different materials such as glass and plastic.

For design, micro centrifuge tube usually has special structural designs, such as caps, bottoms and other parts of the tubes, which can ensure the stability and safety of the samples during the centrifugation process. For example, the cap of a microcentrifuge tube is usually designed to fit tightly, i.e. the locking design, which prevents the sample from spilling or leaking during the centrifugation process. The bottom of the tube, is usually of a conical design, which makes it easy to drain the liquid after centrifugation. In contrast, ordinary centrifuge tubes may not have these special designs.

In terms of use, micro centrifuge tube is more suitable for conducting high-precision and high-sensitivity experiments, such as PCR, gene cloning and other molecular biology experiments, due to their small size and special design. Ordinary centrifuge tubes, on the other hand, are more suitable for general centrifugation operations, such as separating serum and precipitating proteins.

FAQ of Microcentrifuge Tube

Q1：How to use a microcentrifuge tube?

Selecting the appropriate model.
Use an appropriate pipette to carefully transfer the sample to a tube and add appropriate buffer or reagents as required by the experiment.
Mix the sample by gently inverting or tapping the tube.
Seal.
Balance.
Setting centrifuge parameters.
Centrifugation.
Take out.
Sample collection.
Cleaning and sterilization.

Q2：What laboratory consumables can be used with it?

It can be used with laboratory consumables such as pipettes, test tube racks, centrifuges, and cryotubes. Test tube racks can help store and sort, and centrifuges are important tools for sample separation.

Q3：Is a micro centrifuge tube also called an EP Tube? Are there any differences?

In most cases, a microcentrifuge tube is referred to as an EP tube, and in daily laboratory use, both terms generally describe the same type of product. However, there is a slight difference in origin.

The term EP Tube comes from the German brand Eppendorf, which was among the first to produce plastic tubes for micro-scale centrifugation. Over time, laboratories began colloquially calling these small tubes “EP tubes.”

A Microcentrifuge Tube is the generic technical term for small-volume plastic tubes suitable for high-speed centrifugation, commonly in 0.5 mL, 1.5 mL, or 2.0 mL sizes. They are widely used for DNA/RNA extraction, protein precipitation, sample separation, and short-term storage.

Strictly speaking, only tubes made by Eppendorf can be called EP tubes, but in practice, the term has become a common synonym for microcentrifuge tubes. Functionally, there is no difference between them.

One-sentence summary:

EP Tube ≈ Microcentrifuge Tube
“EP Tube” is the brand-origin term, while “Microcentrifuge Tube” is the standard name; there is no functional difference.
