Centrifugation Tubes

Centrifuge tubes are specially designed to be placed in centrifuges to separate liquids, cells or other particles based on their density. During centrifugation, the contents are broken down into their components through rapid rotation around the fixed axis. The centrifugal force pushes the heavier components of the substance downwards, while the lighter ones remain at the top. In this way, solids can be reliably separated from liquids as well as substances of different densities.

Centrifuge tubes as a customised solution

In order to meet the variety of different requirements, we offer centrifuges in a wide range of formats, sizes and materials.

Application and quality

Centrifuge tubes are used wherever the components need to be split - for example, for blood samples to separate the plasma, to isolate proteins or DNA, to collect cell cultures or microorganisms from cultures, for the concentration of particles from environmental samples... The range of applications is diverse.

The high demands placed on these analyses also mean that no compromises can be made when selecting the centrifuge tubes used. At Th. Geyer, we therefore focus on the highest quality and maximum safety - even at maximum speeds and high centrifugal pressure.

The material

You can choose between plastic, glass and stainless steel for the raw materials used. While stainless steel usually plays a subordinate role, plastics such as polypropylene (PP), polyamide (PA), polyethylene (PE) or polycarbonate (PC) are the standard in laboratories and research environments. Depending on the type of plastic, centrifuge tubes can withstand very low to very high temperatures. They are stable against chemicals and can be translucent or opaque, depending on requirements.

Centrifuge tubes made of glass impress with their basic resistance to chemicals, acids, bases and organic solvents. The glass variants score points with their reusability and above-average durability. If required, glass allows a high degree of transparency and offers relatively easy handling If the material is subjected to high speeds during centrifugation, plastic is usually the better choice. Th. Geyer offers centrifuge tubes in both variants.

The sizes

Th. Geyer meets the specific requirements for the dimensions and capacity of centrifuge tubes with a large selection of different sizes. These can be up to 500 ml, while sizes such as 50 mL and 15 mL are available for smaller filling volumes. In the micro range, centrifuge tubes are between 1.5 mL and 0.2 mL, which are mainly used in laboratories. Of course, we offer you a wide selection of all common formats.

The lid

During centrifugation, the lid of the centrifuge tube prevents liquid from leaking out. Traditionally, screw, push-in or plug-in lids are used for this purpose, which are easy to close. Micro centrifuge tubes are usually fitted with a snap-on cap. For very large variants, threaded lids ensure leakage protection. You will find both models with and without lids in our range. Depending on your choice, you can always order stoppers and the like separately.

The base

The different base variants also meet the respective requirements. The conical base with its slightly tapered shape allows for selective material collection, making separation and removal much easier Sample recovery is particularly high. Alternatively, you can also choose between self-standing centrifuge tubes with a flat base or a rounded base.

Benefit from our portfolio of centrifuge tubes

Are you looking for centrifuge tubes for demanding applications? Th. Geyer offers a wide range of the highest quality. Functional, easy to handle and with an attractive price-performance ratio. Please feel free to send us your enquiry or contact us directly in person. We look forward to hearing from you!
