Sticky strips offer a popular alternative to clamps and other holders. Containers are placed directly on the sticky strips and can be shaken at speeds up to 200rpm.

Sticky mats/strips are used to fix shake flasks or other equipment on shakings trays. They provide easy handling and flexible positioning of several sizes and forms of flasks.
Maximum shaking frequencies
in case flat bottom flasks (filled up to 20% nominal volume) are placed on the
sticky strips/mats
| Shaking diameter | Maximum applicable shaking frequency |
|---|---|
| 50 mm | 200 rpm |
| 25 mm | 250 rpm |
| 12.5 mm | 300 rpm |
For higher shaking frequencies, we recommend the use of clamps. Several sizes and forms of clamps for all types of shake flasks are available at Adolf Kühner AG. Please contact Adolf Kühner AG in case you need support concerning the usage of the sticky mats and other accessories.
If it is unsure if the sticky strips/mats can be used for your application, a functionality test must be performed with a sample flask and desired shaking parameters to determine if the sticky strips/mats are suitable for this type of application.
When starting the shaking operation, observe the setup until the desired
shaking frequency is reached. The smaller the shaking diameter of the shaker is
adjusted, the higher the shaking frequency can be set (see table above). In
case shake flasks with baffles are used, the shaking frequency must be reduced.
For close contact to the sticky mat, press the shake flask slightly downwards
after positioning.
The sticky mats/strips are suitable for a working temperature range of 5 to 80°C.
To remove shake flasks from the sticky strips, gently pull at the neck of the shake flask while tilting the flask slightly. Do not pull the flasks directly upwards, this way the shake flask can hardly be removed, and medium may splash onto the inside of the shake flask lid.
Sticky strips have a flat side and a grooved side.
The flat side of the sticky mats/strips is suitable for all shake flasks less than 3 L flask size and / or for shake flasks with a bottom area up to 30 cm2. If you intend to shake a diverse range of objects, this side is recommended.
The grooved side of the sticky mats/strips is suitable for flask with a
filling volume of 3 L or more and / or for flasks with a bottom area of ≥ 30 cm2
or for Fernbach type shake flasks. The construction of the grooved side helps
to remove large flasks of the sticky mat more easily.
The sticky mats/strips lose their stickiness reversibly when they get wet. Therefore, place only dry flasks on the sticky mats. It must be considered that the shake flasks and its contents are heated up to operating temperature of the incubator or at least to ambient temperature. Otherwise, there is a risk of condensation forming on the outer wall of the flasks (especially in incubators with elevated humidity), which causes condensate droplets to get onto the sticky mats and results in losing their adhesive strength.
Carefully remove the sticky strips from the shaker tray by pulling it to the side diagonally (sticky mat may tear!). Flush the sticky strips with decalcified water until all adherent contaminants are removed. Disinfect the sticky strips by spraying in with 70% ethanol. Let the sticky strips / mats dry for 24 h. If the sticky strips / mats are completely dry, they can be placed back on the clean, dry and degreased shaker tray.
Do not radiate sticky strips/mats with UV light! The UV radiation destroys the polymer structure of the sticky strips and releases chemicals which will have adverse effects to the cell growth.
Do not autoclave sticky
strips/mats! Heat treatment will destroy the polymer structure of the sticky
strips / mats.
The expected life of this material is 2 years. Please store the sticky mats under clean and dry conditions at room temperature (for 2 years maximum).
Does our existing range of products not meet your requirements? Do not hesitate to get in touch with us. We would love to hear more about your distinct application. Tailor-made solutions are our business. We will work with you to create an optimal solution for your shaking machine or shaken bioreactor system (OSB).
Do you have an unconventional or unique shaking vessel? Send us a prototype of your vessel and we will develop a suitable clamp. Would you prefer to combine your measuring system with one of our shakers? Do you require a shaking machine with an unconventional feature? We can adapt our shakers to fit your needs.
Each of our customized solutions is specifically adapted to the user's request. Our Kuhner Atelier team provides the expertise and advice to find the optimal solution for each customer and will happily address any questions or technical issues.
If you have any questions regarding our customized solutions or products in general, please contact us: atelier@kuhner.com
GMP production processes often are subject to rigorous safety and process regulations requiring redundant external temperature, humidity, or CO2 monitoring in incubator shakers. To address such requirements, our Kuhner Atelier department has developed a customized solution which incorporates additional sensors monitored by the user's process software.
On the pictures you see an example of a customized solution for redundant temperature monitoring in the ISF1-Z incubator shaker: several magnetic holders are implemented for additional temperature sensors at different locations in the system.
The ISF1-Z Basic Beluga – once a customized project, now one of our regular products – was specifically designed for automation and robotic systems. The lowered shaking platform gives more interior headspace, allowing for a robotic arm to reach into the chamber and grab any vessel from the shaking tray. The ISF1-Z Basic Beluga can be integrated into many areas of automation, such as screening for an optimal cell line, media development, or analytical applications.
The pin-clamps are ideal for cleanrooms and areas where sticky mats or other standard clamps are unsuitable. The clamps have been designed for easy cleaning and efficient handling of samples. Made of stainless-steel pins and aluminum bottom plates, they are compatible with all Kuhner universal trays. A replaceable rubber cover prevents the bottles from rotating in the clamp. The shaking speed is limited to 180 rpm at 50 mm shaking diameter. The pin-clamps are available for 125 mL, 250 mL, and 500 mL Erlenmeyer flasks, as well as 500 mL and 1000 mL Schott laboratory bottles.
Do you perform biological cultivations in a comparatively large-sized, a custom-made, or an unconventional shaking vessel? And would you like to obtain online monitoring data to gain a better understanding of your bioprocess?
Kuhner offers customized caps to connect all types and sizes of shaken cultivation vessels to the Kuhner TOM online monitoring system. This enables the customer to monitor online respiration and metabolic activity of microbial and cell cultures in these vessels as well.
For instance, Kuhner has designed a customized Kuhner TOM cap for Thomson Optimum Growth Flasks which are routinely used for cell culture processes. This Kuhner TOM cap works for the 1.6 L, 2.8 L, and 5 L Thomson flasks. The three ports of the cap are for gas inlet, outlet to the sensors, and pressure equilibration (port without tube). The Thomson-Cap is reusable by autoclaving at temperatures up to 121°C without losing its mechanical performance.
