What is the function of centrifuge tubes?

Centrifuge tube for containing liquid during centrifugation, the rapid rotation by separating the sample into its component around a fixed axis. Most tubes have a conical bottom, which helps to collect any solid or heavier portions of the samples were centrifuged.

Plastic centrifuge tubes physical and chemical properties:

Provide the following information as a general guide in determining the suitability of a centrifuge tube for your application. In addition, we recommend that you follow the centrifuge manufacturer’s instructions and run the appropriate conditions for the test to determine before the start of critical operation.

Perform a leak test of the centrifuge tube. When used in a well-balanced rotor, it must not be damaged or leaking. The rotor is supplied with suitable brackets, brackets and adapters that fully support the tube when used as described in this chapter. These test tubes are disposable. Reuse is not recommended as it may break or leak.

Centrifuges recommended operating temperature range of 0-40 ° C. The suitability of these pipes below 0 ° C, the solution depends on the storage and the storage conditions. Highly recommended to try to run under actual conditions to test whether the tubes are suitable for cold storage.

Only for centrifugation; it can be stored in the tube at a lower temperature. Test in real conditions before use.

The RCF (relative centrifugal force) of a disposable centrifuge tube is determined at room temperature using a centrifuge tube rinsed with water to nominal volume and centrifuged in a horizontal rotor housing for 5 minutes.The centrifuge should be equipped with the recommended brackets, adapters and pads that fully support the tubes.If an angular rotor is used or if there is no suitable support, the RCF value is lower. The use of liquids other than water can also lower the FCR. See the specifications of the centrifuge and the nomogram to determine the speed to reach the maximum RCF.

Chemical compatibility of disposable plastic centrifuge tubes

Mechanical strength, flexibility, color, weight and dimensional stability of all the tubes plastic centrifuge is allocated variably by chemicals with which they come into contact. specific operating conditions, particularly the temperature, the relative centrifugal force (RCF), rotor type, the support structure and the working length may also affect the performance of the pipe.
