Product Recommendation｜A centrifuge tube that is essential for the laboratory!

Centrifuge tubes are the most commonly used experimental consumables in laboratories in the fields of biology and chemistry. It can be said that centrifuge tubes are used in every biochemistry laboratory. It is mainly used for the separation, preparation and storage of various experimental samples. It has a variety of specifications to choose from depending on the amount of samples contained.

So how should we choose centrifuge tubes? Generally speaking, the first thing to consider when choosing a centrifuge tube is its capacity, secondly its chemical compatibility, and finally its relative centrifugal force (maximum withstand centrifugal force).

Choose according to capacity

Commonly used centrifuge tubes have capacities of 1.5mL, 2.0mL, 15mL, 25mL, 50mL, etc. You can choose according to the sample size of the experiment. It should be noted that the centrifuge tube should not be overfilled, generally no more than 2/3 of the volume of the centrifuge tube. However, in some cases, such as ultra-high-speed centrifugation, the centrifuge tube needs to be filled with liquid to prevent deformation.

Select based on material chemical compatibility

The centrifuge tubes we use now are basically plastic. Commonly used materials include polypropylene (PP), polyamide (PA), polycarbonate (PC), and polyethylene terephthalate (PET).

Among them, centrifuge tubes made of PP can withstand high speeds, can be sterilized at high temperatures, and can withstand most organic solutions. Therefore, most centrifuge tubes on the market are made of PP.

Select based on relative centrifugal force

The centrifuge tube has a maximum speed it can withstand. When observing the working rate of a centrifuge tube, it is best to look at RCF (relative centrifugal force) rather than RPM (revolutions per minute), because RCF (relative centrifugal force) takes gravity into account, while RPM only counts the rotation speed of the rotor.

So when choosing a centrifuge tube, calculate the maximum centrifugal force you need to find a suitable centrifuge tube. If you don't need a high speed, you can choose a centrifuge tube with low centrifugal force, which will also cost less.
