CO₂ control

CO2 control is essential when working with mammalian cell cultures. Kuhner was the first company to manufacture and supply incubator shakers with CO2 control more than 15 years ago and continues to offer this option. More.


Cooling

All Kuhner incubator shakers can be fitted with cooling. The refrigeration system is regulated by a fully digital PID control ensuring minimal energy consumption. The cooling is switched on only when required as determined by the chamber temperature and set point. More.


Humidity control

Humidity control is an important factor in successful fermentation. Evaporation from microtiter plates, or when cultivating in flasks for long periods (e.g. cell cultures), can be significantly reduced with humidification. More.

To reduce evaporation from shake flasks or microtiter plates a water bath is placed inside the incubator. This water bath is fitted with an automatic water supply.


3mm / 1000rpm

With this new option for the ISF4-X incubator shaker, up to two shaking units (out of four) can run with shaking frequencies up to 1000 rpm at 3 mm shaking diameter. This combination is specifically recommended for users of 96 deep-well microtiter plates with high filling volumes (e.g., cell culture in deep-well plates). The shaking table is specially designed for up to 20 microtiter plates, and it is also suitable for the Duetz system. The shaking diameter is user-adjustable to any other standard configurations of 6, 9, 12.5, 19, 25, 50, and 70 mm.

The option 3 mm/1000 rpm is only available for ISF4-X with active cooling.

The temperature accuracy, absolute for this option 3mm/1000rpm is +/-0.45°C (at 37°C).

Existing ISF4-X incubator shakers can be retrofitted with this option.

ISf4-X 3mm / 1000rpm

Illumination unit for photosynthesis (LED)

The ceiling of any Kuhner incubator shaker can be fitted with LED modules for the cultivation of phototrophic organisms. The control module allows full programming of night/day cycles and variable light intensity.

LED

Additional integrated UV lamp

In the space between the incubator chamber and the rear outer wall of the ISF4-X, a UV lamp can be mounted. This can be used while shaking to decrease the number of germs in the circulated air.


Light shade plate

The light shade plate is an 100% light blocking barrier that is easily placed in front of the door windows of an ISF4-X using a magnetic clip system. It protects light sensitive media or organisms inside the shaker incubator from UV, artificial and/or daylight. To take a look at the cultures inside the incubator one can simply lift up the light shade plate. When light protection is no longer required, the plate is easily removed and can be stored by attaching them to the side walls of the shaker cabinet (if accessible) using the magnetic clips.

Also, check out the Kuhner EquipNote "Light protection for Kuhner incubators".

Lichtschutzblende

Black window

Available for light sensitive medium or organisms. Any Kuhner incubator shaker can be delivered with blackened windows to prevent unwanted daylight or UV radiation inside the incubator.


Touchscreen

This option includes a 9-inch touchscreen with our Kuhner Insight Software. The touchscreen has been designed for simple operation, monitoring and programming. It can also be retrofitted to existing incubator shakers. More.


Pull-out table

The pull-out table is designed for the ISF1-Z and ISF4-X incubator shakers as well as the Rack System. This remarkable device makes loading and unloading trays much easier.

Ausziehtisch

Dual table

The dual table is an easy and economical way of doubling the shaking capacity. The dual shaking table consists of two levels. Each level will accept an E (420 x 420 mm), EX (500 x 420 mm) or F (800 x 420 mm) size tray.

The dual table is available with a fixed distance between the two levels of either 120, 160, 180, or 200 mm. At the maximal distance of 200 mm the lower level accepts 125 mL, 250 mL, and 500 mL Erlenmeyer shake flasks.

However, with the dual table the shaking speed is limited to 200 rpm at a shaking diameter of 50 mm (all other maximum shaking frequencies, dependent on the shaking diameter, can be withdrawn from the ISF4-X manual).

Doppelschütteltisch

EPFL-table

Do you perform screenings with a large number of 50 ml bioreactors (TPP, Falcon etc.) or microtiter plates? Would you like to shake different cultivation vessels on the same shaker and be able to change the composition quickly and easily? Then the Kuhner EPFL-table is the optimal solution for you. The shaker table has 5 individual clamps, so that 5 different holders or EPFL universal trays can be clamped. By opening a clamp, a single holder or universal tray can be easily removed from the incubator shaker and processed under a clean bench while the remaining holders/trays keep on shaking.

The EPFL universal tray can be equipped with clamps for Erlenmeyer flasks, Schott laboratory bottles, test tube holders, microtiter plates or customer-specific holders. Rearrangement of these clamps and holders is quick and easy. The universal tray can also be equipped with sticky strips. Sticky strips are used to fix shake flasks or other equipment on shaking trays. They offer easy handling and flexible positioning of different sizes and shapes of shake flasks and other vessels.

Special holders for microtiter plates, 50 mL centrifuge tubes (Falcons) and 600 mL reaction vessels are also available for the EPFL-table.

Instead of 5 individual holders, a large Kuhner F-tray (800 x 420mm) can also be clamped onto the shaker table.

For the smaller (incubator) shakers from Kuhner, correspondingly adapted EPFL-tables with 3 or 4 clamps are available (LT-X: 3 clamps, LS-Z: 3 or 4 clamps).

AerationSystem and FlowCon

AerationSystem and FlowCon provide the ideal system for carrying out cell/stem cell cultivations in a simple, fast, and inexpensive manner.

Lab shakers in temperature-controlled rooms and incubator shakers without humidity and CO2-control can be equipped with the AerationSystem and FlowCon to easily implement humidification and a controlled gas composition for carrying out cell cultivations (e.g., CHO, HEK cells…) in shake flasks.

AerationSystem

The FlowCon is a stand-alone gas mixing device and provides a precise gas composition and flow rate. Simultaneously, the AerationSystem (consisting of GasDivider and special shake flask caps) humidifies and distributes the gas flow evenly to the connected shake flasks. Evaporation losses from the shake flasks are significantly reduced, which is particularly advantageous for very long cultivation times (such as cell culture processes) and contributes to successful cultivations. Another advantage is that opening the incubator door does not affect the gas composition in the shake flasks when they are connected to the aeration system.

By controlling the composition of the inlet air with the FlowCon, it is not only possible to supplement CO2 but also to increase or reduce the concentration of oxygen (O2) or implement anoxic conditions using nitrogen (N2). This control of gas compositions allows for a variety of different applications, including stem cell processes for gene therapy or cultivated meat that require a physiological oxygen concentration at 5% O2 or anaerobic cultivations in a nitrogen atmosphere.

FlowCon

The patented Kuhner GasDivider humidifies the mixed, dry gas flow provided by the FlowCon and distributes it precisely and evenly across the attached shake flasks, independent of shake flask type, tube length and any filters in-between. As the GasDivider is placed on the shaking tray of the (incubator) shaker, the gas flow is also perfectly adapted to the temperature of the incubator shaker or temperature-controlled room.


Perspex cover

To prevent accidental operation of the controllers, the panel can be protected by a perspex cover.


TabCom

The TabCom option from Kuhner consists of a cable for power and data with the connection port integrated in the shaking table (see pictures below). A cable guide prevents the cable breaking and ensures secure data recording. The flexibility of TabCom means online measurement systems can be easily integrated.
