Lab scientists need reliable tubes that can hold up to the rigorous demands of the laboratory environment. Choosing the right tube can help ensure accurate and precise results that prevent costly mistakes. Centrifuge tubes are a key part of many lab techniques, including cell and tissue culture work, blood work, chemical analysis, molecular biology, immunology and microbiology.

Whether you're working with a small sample or a large one, finding the right centrifuge tube can make all the difference in your results. These clear or colored plastic containers are used during laboratory centrifugation, a process that separates liquids from solids or components within mixtures. A wide range of sizes are available, so you're sure to find the right one for your particular application.

When buying centrifuge tubes, look for a quality product that will stand up to the rigors of laboratory use. Choose from a variety of materials, including borosilicate glass, polypropylene and polycarbonate. These plastics are resistant to most chemicals and alcohols, as well as many solvents. They're also durable enough to withstand high-speed spinning, making them ideal for lab centrifugation.

You can also find a selection of colors, shapes and caps to suit your specific needs. For example, some types of centrifuge tubes feature a conical bottom that allows you to aspirate from a smaller surface area. This reduces left over sample waste and makes it easier to get an accurate reading of your liquid biochemical solution. Other centrifuge tubes are constructed with a shoulder that hangs in the rotor trunnion rings, which helps to maintain the integrity of the sample during high-speed spinning.

Another consideration when buying centrifuge tubes is the size of the opening. A tight fit is critical, as a loose tube can potentially leak during the spin. To avoid this, it's recommended that you only fill the tube three-fourths of the way full. Any more than this may cause leaking or loss of your valuable sample.

To make your lab more organized, consider purchasing a set of centrifuge tubes that are specially designed for laboratory use. Some have a stacking feature that keeps them in place while you work, while others have numbered and lettered slots for labeling. Ideally, you should also opt for tubes that are Rnase and Dnase free, non-pyrogenic and non-cytotoxic. This will keep your samples safe from contaminants that could impact the result of your lab testing. Also, some tubes are manufactured with a plug-seal cap that makes them totally leakproof. This is especially useful if you're using the tubes for storing volatile liquids such as corrosive acids.
