Ultrafiltration centrifuge tube is a tool used for the separation and concentration of proteins, viruses, and other macromolecules. It is a hollow tube made up of a semi-permeable membrane that separates the small molecules from the large ones. The ultrafiltration centrifuge tube functions based on the principle of centrifugation in which the samples are spun around a central axis to create a force that moves the molecules through the membrane.
The ultrafiltration centrifuge tube is commonly used in biological research laboratories for various applications such as protein purification, concentration, and desalting. It is essential in the removal of low molecular weight contaminants from protein samples before further analysis.
The ultrafiltration centrifuge tube has a maximum capacity of 20 ml, and it is designed to fit standard centrifuges. It is made of a durable polypropylene material that is capable of withstanding high-speed centrifugation. The tube has a top and bottom cap that forms a seal to prevent leakage during centrifugation.
To use the ultrafiltration centrifuge tube, the sample containing the target molecule is added to the tube and spun in a centrifuge at high speeds. The centrifugal force pushes the smaller molecules through the semi-permeable membrane, leaving behind the larger molecules in the tube. The filtrate is collected from outside the tube and can be further analyzed or used for downstream applications.
