A laboratory centrifuge is a piece of equipment that spins samples of liquid at high speeds. Lab technicians place the sample into a tube-shaped container that is inserted into the centrifuge’s slot. The spinning motion causes the denser particles in the sample to gather at the point that is farthest away from the axis, while the lighter particles collect near the center of rotation. This separation is then used to identify the sample’s contents and its components.
Centrifuge tubes are available in several sizes, capacities and materials to fit different purposes. The most popular are made of polypropylene and have a sealing closure. These durable, sturdy plastic containers withstand high centrifugal forces of up to 11,600 x g, making them ideal for applications such as lipid fractionation. They also have a flat top and engraved graduations, so they can be easily labeled with the details of each sample.
Glass centrifuge tubes, which are more expensive and breakable, are less common. Most laboratories now use disposable microcentrifuge tubes, which are a more convenient and economical option. These tubes are created from USP Class VI virgin polypropylene in a sterile manufacturing environment, which is an important factor for labs that work with hazardous chemicals or live organisms. Typically, these plastic tubes are also autoclavable.
A good laboratory will make sure that all its supplies are safe for the entire process, from storage to disposal. The right storage containers and labels help ensure that the smallest of samples are properly labeled and stored for future use. The right containers will also have tamper evident strips and resealable zip-tops to prevent spills, contamination and loss of precious samples. In addition, the best microcentrifuge tubes will be labeled with a quality certificate that includes information such as part number, batch number and expiration date. They will also provide a sterility assurance level and dosage, endotoxin/pyrogen free certification and RNase/DNase/DNA free certification for molecular biology applications.

Laboratory centrifuges are pieces of equipment found in many labs that spin liquid samples at high speeds. The spinning action separates the components of a sample by their different densities. Centrifuge tubes are used with these types of lab devices to contain the samples. Lab centrifuge tubes are available in a number of sizes and can be used for many different lab purposes.
Several factors can influence the centrifugal force of a sample, such as the rotation speed of the rotor, the volume of the liquid, the presence of solids, and the viscosity of the liquid. Usually, protocols specify the acceleration of the sample in multiples of g. This value is calculated as the product of the rotational speed (in revolutions per minute) and the radius of the rotor’s circular cross-section.
These microcentrifuge tubes are able to withstand centrifugal forces up to 20,000 x g. They are made of polypropylene and feature a flat, piercable cap with a writing surface on the side.
