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.
Steam Indicator Strips
Class 4 Multi-Variable Steam Indicator Strips
Class 4 Multi-Variable Steam indicator strips are designed to be used in steam sterilizers operating at 134 °C -3.5 minutes. The indicator strips can be used in every pack and will provide assurance of steam penetration into the packs.The water based and non-toxic chemical indicator in compliance with ISO 11140-1 will show a clear and accurate color change from blue to black after successful steam sterilization. PMSSteriTest indicator strips are cost effective and can be divided into two separate pieces for more economical use....

Bowie-Dick Test Pack
These Bowie-Dick Test Packs are pre-assembled, single use test packs designed to evaluate the performance of the air removal system of pre-vacuum assisted sterilisers in compliance with EN 285 and operating at 134 °C and 3.5 minutes. An indicator sheet printed with water based, non-toxic chemical indicator is placed in the center of each pack. The uniform colour change of the indicator after steam sterilisation indicates that all air was removed and replaced by steam. The backside of the indicator sheet contains fields to be filled out and it can be kept as a permanent record for traceability purposes....

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.
