What is a Centrifuge tube?

A centrifuge tube is a thin, cylindrical tube with a round bottom and a cap, used in a laboratory centrifuge. Centrifuge tubes are made of plastic or glass and are used to separate substances based on their density. When placed in a centrifuge and spun at high speeds, the heavier substances will settle to the bottom of the tube, while lighter substances will remain near the top. Centrifuge tubes are commonly used in a variety of scientific and medical applications, including separating blood components, purifying proteins, and isolating DNA. They are available in a range of sizes and can hold a few milliliters to several hundred milliliters of liquid.

Characteristics of Centrifuge tube

There are several characteristics of centrifuge tubes that are important to consider when choosing the appropriate tube for a particular application:

• Material: Centrifuge tubes can be made of plastic or glass. Plastic tubes are more resistant to breakage and are often used for routine laboratory procedures. Glass tubes are more durable and are often used for more demanding applications, such as high-speed centrifugation.
• Size: Centrifuge tubes are available in a range of sizes, from a few milliliters to several hundred milliliters. It is important to choose a tube that is appropriate for the volume of sample being processed and the size of the centrifuge being used.
• Cap type: Centrifuge tubes have either a screw cap or a snap cap. Screw caps provide a secure seal and are commonly used for tubes that will be stored or shipped. Snap caps are easier to open and close and are often used for tubes that will be frequently accessed during a laboratory procedure.
• Graduation marks: Some centrifuge tubes have graduation marks, which allow the volume of liquid in the tube to be easily measured.
• Sterility: Some centrifuge tubes are sterile and are suitable for use in sterile environments or for processing biological samples.

What to consider when choosing centrifuge tubes?

Without a doubt, centrifuge tubes are the lab supplies that must withstand the most strain. To avoid costly and time-consuming spills within your centrifuge, you should consider the following aspects while selecting tubes.

Relative centrifugal force

Manufacturers of tubes typically mention the relative centrifugal force (RCF) their tubes can withstand. Since pricing can vary based on this value, you should first determine the RCF required for your workflow and then search for tubes that can bear these forces.

Chemical impermeability

As your tubes are exposed to both the RCF and your samples, you should always examine their chemical resistance to decide if they are appropriate for your process. Polypropylene (PP), polyallomer (PA), polycarbonate (PC), polyethylene terephthalate (PET), and glass are common tube materials.

Autoclaving

The ability to autoclave centrifuge tubes also depends on their composition. Glass, PP, and PA tubes are typically autoclavable (confirm with the tube manufacturer), however PET tubes cannot be autoclaved. PC tubes may be autoclaved, however frequent autoclaving diminishes their durability and shortens their lifespan.

Size

The optimal tube size is determined by the sample volume. In general, tubes should be at least three-quarters full, and some must be totally filled, to avoid excessive material stress and potential tube failures. Before choosing a tube size, it is best to examine the manufacturer’s specs. Adapters are available for the vast majority of instruments in the event that the sample-appropriate tube is too small for the centrifuge.

Screw cap tubes versus snap cap tubes

The sealing mechanism of your tubes is an additional aspect of centrifuge security. Particularly when handling a large number of samples, snap cap tubes are more straightforward to close. Screw cap tubes, on the other hand, offer a superior seal and cannot accidentally open, especially when handling volatile or heated samples. You must consequently strike the optimal balance between efficiency and safety.
