Quick to Know Types of Centrifuge Tubes

Some brief introductions of centrifuge tubes from these questions:

  1. What are the types of centrifuge tubes?
  2. What is the function of the centrifuge tube cap?

Brief introductions of the centrifuge tube:

50ml centrifuge Tube Sterilized centrifuge bottles

The type of centrifuge tubes:

1.Large centrifuge tube (500mL, 250mL) Ordinary centrifuge tube (50mL, 15mL) Microcentrifuge tube (2ml microcentrifuge tubes,etc)

2. According to the bottom:

Conical centrifuge tubes, with a conical bottom, are the most used types of centrifuge tubes: flat-bottom tubes, round-bottom tube

3. According to the lid:

Capping centrifuge tubes, the tubes sealed by pressing, commonly found in microcentrifuge tubes, screw cap  tubes, and can above flat caps (the top of the cap is flat) and plug caps (the top of the cap has a plug shape)

The material of the centrifuge tube:

 1. Glass centrifuge tube:

  • When using a round glass centrifuge tube, the centrifugal force keeps not too large.  People should not use it for high-speed centrifuges and use a rubber pad to prevent the tubes from breaking.
  • People should close the cap of the centrifuge tube well and fill the liquid (for high-speed centrifuges and using an angle rotor) to prevent overflow and loss of balance.
  • If not avoided spillage, the consequence is to contaminate the rotor and centrifugal chamber, affecting the regular operation of the inductor.
  • Steel centrifuge tube: The steel centrifuge tube has high strength, no deformation, heat resistance, frost resistance, and chemical corrosion resistance.

2. Plastic centrifuge tube:

  • A translucent or transparent plastic centrifuge tube is one of the benefits of a plastic centrifuge tube.
  • The hardness of the plastic tube is small, and the sample of the plastic centrifuge tube can be taken out by puncture.
  • Most of the tube has caps, which most of which are for preventing sample leakage, especially when used for radioactive or highly corrosive samples.
  • When choosing the plastic tube, we should also pay attention to check whether the tube cover is tight and whether you tight covered it during the test, so as to achieve the inversion without leakage;
  • Know that in centrifuge tubes, the commonly used materials are polyethylene (PE), polyethylene Carbonate (PC), polypropylene (PP), etc.
  • In fact, we often consider polypropylene plastic centrifuge tubes as much as possible when selecting plastic tubes.

The role of the cap in the centrifuge tube:

  • When used for radioactive or corrosive samples, prevent the sample from leaking.
  • Prevent the sample from volatilizing.
  • Support the centrifuge tube to prevent deformation of the centrifuge tube.

Matters needing attention of centrifuge tubes:

  1. When selecting plastic tubes, consider polypropylene PP plastic tubes as much as possible.
  2. Pay attention to check whether the tube cover is tight and whether you are tight-covered during the test, so as to achieve the inversion without leakage.
  3. When using the centrifuge tube, do not use one tube multiple times.
  4. Pay attention to the volatilization of the sample and the leakage of some radioactive or corrosive samples; during the storage process, you should seal it well.
