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.
Learn more about Kuhner’s CO₂ control system.

A reliable control of O2 is essential for cultivating cells (proliferation and metabolism of stem cells) and microorganisms with low/no oxygen demand. The O2 controller reduces the O2 level from ambient (20.95% at dry air; normoxia) to approximately 0% O2 (hypoxic). A digital PID controller adjusts the N2 flow rate to maintain the desired O2 value.

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.

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.

Our newly developed EcoDew®-Technology provides precise humidity control. 

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.

The LT-X is completely made of stainless steel. It can either be painted white or have a processed stainless steel look.

As in a biological safety cabinet, the chamber of a Kuhner incubator shaker can also be sterilized with an integrated UV lamp. The lamp is situated to maximise irradiation of the chamber and shaking table. The UV lamp has a clearly marked external switch and when the door is opened, the UV-lighting is automatically switched off.

IQ-OQ (Installation Qualification and Operation Qualification) is an equipment qualification according to GMP procedure. Kuhner offers this service which can also be carried out at the customer’s premises.

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) or EX (500 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 LT-X manual).

The Kuhner EPFL-table offers maximum flexibility for screening and cultivation with different vessel types. Its individual clamps allow holders and universal trays to be quickly exchanged while the remaining vessels continue shaking. Compatible with microtiter plates, 50 mL centrifuge tubes, Erlenmeyer flasks, laboratory bottles and other cultivation vessels, the EPFL-table can be easily adapted to changing applications. Universal trays can also be equipped with sticky strips for flexible positioning of vessels of different sizes and shapes.

EPFL-tables are available for different Kuhner shaker models with 3, 4 or 5 individual clamps.

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.

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.

Check out the Kuhner EquipNote "Light protection for Kuhner incubators".

Kuhner has designed a new light shade plate for the LT-X. This plate is easily placed in front of the door window and held in position with clamps. It prevents radiation affecting the contents of the incubator chamber and protects light sensitive media from UV, artificial and/or daylight.

Simply lift the light shade plate to look at the cultures without opening the incubator door. When light protection is no longer required, the plate is easily removed.

Check out the Kuhner EquipNote "Light protection for Kuhner incubators".

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

The TabCom option from Kuhner consists of a cable for power and data with the connection port integrated in the shaking table (see picture 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.

This option includes a 10.1-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.

Kuhner TOM (Transfer-Rate Online Measurement) measures online oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR) and the respiratory quotient (RQ) in up to 16 individual shake flasks for better process understanding and informed process development. TOM is easily installed in any Kuhner shaker and can be operated with various flask types and sizes including single use shake flasks. Kuhner TOM has zero footprint on the shaker tray as it is mounted above (see picture below).

Adapt the Kuhner LT-X to your vessels and workflow with a wide range of accessories. Choose the right trays, clamps and adapters for your flasks, tubes and plates, and make the most of your bench space. All accessories are designed by Kuhner to fit your system and to be changed quickly as your experiments change.

The universal tray can be fitted with clamps for Erlenmeyer flasks, test tube holders, microtiter plates, or custom made holders to suit your requirements. 

Rearranging these clamps and holders is quick and simple.

The clamps are riveted onto these trays and cannot be removed. They offer maximum stability and will often hold a larger number of flasks than universal trays. These trays are available in a variety of flask clamp sizes from 25 to 6000ml.

A tray fitted with sticky strips is especially useful for flasks shaken at low speeds (up to 200 rpm). The flask is placed directly on the sticky strip without the need for any other support. Flasks of all sizes can be used. Sticky strips are available individually or in sets and can also be supplied already fitted to a tray. The EX-size tray accepts five strips. 

The PC-plate increases the adhesion of the sticky strips. This is particularly helpful if using flasks >500ml.

The pin-clamps are ideal for cleanrooms and areas where sticky mats or other standard clamps are not suitable. The clamps have been designed for easy cleaning and efficient handling of samples. The stainless-steel pin-clamps are compatible with all Kuhner universal trays. The shaking speed is limited to a maximum of 180 rpm at 50 mm shaking diameter.

Kuhner has designed trays specifically for microtiter plates. Handles at the front of the tray open and close the special clamping mechanism allowing plates to be loaded and unloaded. Trays of different heights (22, 47 and 77mm) allow the stacking of up to four microtiter plates. The trays are available in three sizes and suitable for all types of plates (deep well, low well, 24, 48 and 96 well).

Kuhner has designed a new tray for microtiter plates. This tray is fitted with springs which allows each well plate to be loaded and unloaded individually. The tray is available in three sizes: E (420x420mm), EX (500x420mm) and F (800x420mm).

This new tray is particularly suitable for the special holder with filter lid for deep well microtiter plates.

The whole tray is covered with a rubber mat and is particularly suitable for shaking containers at low speed (e.g. blood bags).

Kuhner has also designed a special tray for shaking separating vessels. This very flexible tray can take vessels of various sizes. It is also possible to add a second layer and double the capacity. Movable retaining rods allow vessels to be installed easily.

These trays offer an alternative to both clamps and sticky mats and are ideal for tall containers. The tray is covered with a rubber mat and has an upright at each corner. The EX size tray is fitted with four cross supports. These support bars securely clamp containers.

The dual tray offers two shaking levels and doubles the capacity. It is available in EXU, EX, FU and F size and the upper tray can be removed.
Please note the shaking speed is limited.

This stacking adapter is designed for stacking a LT-X on an ISF1-X/Z incubator shaker. Extra work space on the adapter allows room for flasks or a small machine, as well as the LT-X, thus creating a greater working area.

For a comfortable working height Kuhner offers floor stands for both the ISF1-Z and LT-X incubator shakers. These are available in a choice of 400mm (2 x LT-X) or 765mm (1 x LT-X) high.

Floor stands with wheels are available for both the ISF1-Z and LT-X incubator shakers. These stands enable the user to move the machines easily. However, the shaking speed is limited.

The Kuhner LT-X incubator shaker can be fitted with a shelf allowing cultivation in petri dishes. One or two shelves can be placed above the shaking table and fixed to the chamber walls with four screws.

To reduce evaporation from shake flasks or microtitre plates a stainless steel water bath can be placed inside the incubator. This water bath is not fitted with an automatic water supply and must be topped up manually.

Kuhner has designed a new light shade plate for the LT-X. This plate is easily placed in front of the door window and held in position with clamps. It prevents radiation affecting the contents of the incubator chamber and protects light sensitive media from UV, artificial and/or daylight.

Simply lift the light shade plate to look at the cultures without opening the incubator door. When light protection is no longer required, the plate is easily removed.
