Conical Centrifuge Tube

Conical Centrifuge Tube

PakGent Conical centrifuge tubes are essential tools in laboratories, used to separate different components of liquid mixtures based on their density. The conical bottom centrifuge test tubes are made of plastic or glass and come in a variety of sizes and they are designed to withstand high speeds and g-forces, making them ideal for use in centrifuges. When using a centrifuge, the tubes should be filled with a sample and balanced with an equal weight of the same material in the opposite tube. The centrifugal force causes the denser components to settle at the bottom of the tube and the lighter components to remain at the top, allowing the components of the sample to be separated and analyzed individually.

Micro Centrifuge Tube

Micro Centrifuge Tube

A microcentrifuge tube, also known as a microtube or a PCR tube, is a small centrifuge tube used in laboratory experiments and clinical trials. These small centrifuge tubes are typically made of plastic and is designed to withstand high centrifugal forces. Mini centrifuge PCR tubes are commonly used in molecular biology and biochemistry experiments to separate components of a sample based on their size and density, such as proteins and nucleic acids. These mini centrifuge PCR tubes can also be used for storage of samples, as well as for mixing and transporting them. The small capacity of the mini centrifuge pcr tubes ensures that samples are not wasted and that the experiment can be easily scaled up or down.

Understanding Centrifuge Tube Materials and Their Properties

Understanding Centrifuge Tube Materials and Their Properties

Disposable centrifuge filter tubes are small cylindrical tubes used in centrifugation, a process in which substances are separated from a liquid suspension by spinning them in a centrifuge. Disposable centrifuge filter tubes are typically made from glass or plastic materials.


Glass graduated centrifuge tubes are made from borosilicate glass by centrifuge tube manufacturers, which is a type of glass that is highly resistant to thermal shock and chemical corrosion. It is also relatively inert, meaning that it does not react with most laboratory reagents and samples. Glass centrifuge tubes are usually transparent and can be used to measure the volume of a sample.


Plastic centrifuge tubes are typically made from polypropylene, polycarbonate, polyethylene, acrylic, or polystyrene. These plastics are generally more durable than glass and can withstand higher temperatures and pressures. They are also generally more economical than glass, so they are often used for large-scale sample preparation. Plastic centrifuge tubes are often opaque, making them useful for light-sensitive samples. They are also typically autoclavable, meaning that they can be sterilized for reuse.
