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.
ND13, ND18, ND20 Headspace, ND24 (EPA)
The chemically resistant and autoclaveable storage boxes made of PP are temperature-resistant from -80 °C to 125 °C and stackable. They offer space-saving storage and simple transport for several types of vials. The alphanumerically coded positions ensure that each sample vial can be clearly identified in the box....
Pipette controller
Pipetting made easy - the wireless LABSOLUTE® Pipette assistant ensures comfortable working with glass and plastic pipettes (0.1 - 100 ml).
- Effortless pipetting thanks to the ergonomic grip and smooth-running buttons
- Simple operation with one hand
- High working speed: a 25 ml pipette is filled in less than four seconds
- Extremely quiet and powerful motor with two speed settings
- Dispensing without motor, using gravity via "G" setting
- The charging device prevents overloading or heating of the battery
- Exchangeable membrane filters protect the device mechanism against contamination
- Differently coloured autoclavable cones allow customization
Crimping tools
The crimping and decapping tools feature a chemically resistant surface lacquer that has been developed especially for use in the laboratory. Additionally, the crimping tools have hardened closing jaws with a special alloy that guarantee a long service life. The crimping pressure and crimping height of the crimping tools can also be adapted to the design of the crimp neck and septal thickness....

Vial racks, acrylic
The stackable vial racks made of transparent acrylic or blue PP allow the easy handling and secure transport of sample vials.
Transparent acrylic allows the fill level of the sample vials to be easily checked. PP is not transparent, but more robust than acrylic.

Crimping tool, pneumatic, manual
The pneumatic hand-held crimping tool makes crimping and decapping of vials very easy and ergonomic. The time spent to crimp or decap a series of many samples, especially, is shortend clearly. As the balancer compensates the weight of the pneumatic crimper, steady and precise crimping is no problem....

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 qualityCentrifuge 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 materialYou 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.
