Centrifuge Tubes Frequently Asked Questions
How can I find the right tube for my application?
Each tube must withstand different requirements for different applications. You may have to consider various factors (e.g. centrifuge type, max. g-force, plastic material, and/or others special needs such as adapters and rotors). Check out our table to find often used methods with their ideal vessel type.
What is the difference between tubes with snap and screw caps?
Centrifuge tubes with snap caps can be opened and closed with one hand and are thus easily accessible with a needle or syringe. Tubes with screw caps offer a particularly secure closure but require both hands for handling.
What material are centrifuge tubes made of?
Centrifuge tubes are usually made of polypropylene (PP) , polyallomer (PA), polycarbonate (PC), or polyethylene terephthalate (PET). Both PP and PA tubes offer good chemical-resistance while PC and PET are generally less chemical resistant. Consider your samples and material compatibility when selecting your centrifuge tube to make sure that the sample components will not harm the plastic tube material.
Can you reuse centrifuge tubes?
Most centrifuge tubes, such as those made from polypropylene (PP), are recommended for single use only to ensure accuracy in use. In addition to glass tubes, only entrifuge tubes made of cfluorinated ethylene propylene (FEP) are durable enough to be reused.
Should I use a conical or free-standing centrifuge tube?
Free-standing tubes save space and prevent spillage. Centrifuge tubes with a conical bottom are also indispensable in every laboratory, as only conical tubes can be used in a microcentrifuge. In addition, only tubes with a conical bottom fit into a microcentrifuge. If you decide to use a conical bottom, you will also need a tube rack.
