Space saving stackable incubator shaker

The Kuhner LT-X (Lab-Therm) incubator shaker has the same capabilities as the larger ISF1-X and ISF4-X models. The incubator shaker was specially developed to address the shaking needs of the biotechnology and pharmaceutical industries. The practical size of the LT-X means it will fit in any laboratory.

Performance characteristics

  • Fits into any laboratory 

  • Used in biotech and pharmaceutical industries

  • Accepts flasks up to 6 litres

  • Two units can be stacked without the need for special kits or tools

  • Humidity, CO2 and O2 control available

Extra space

Extra space

Exceptional chamber height means flasks up to 6 litres capacity can be accommodated. If using smaller flasks, there is sufficient head height to fit one or two stationary trays above the shaking table. It is also possible to stack two LT-X together without the need for special kits or tools.

Direct drive

Functionality through direct drive

Direktantrieb

The maintenance-free direct drive guarantees long and economical performance from the LT-X. The shaking diameter can be changed at any time thanks to Kuhner’s unique direct drive system. The integrated drive is protected from spills and the all stainless steel interior has a drain at the back for any unwanted liquids. The chamber can be cleaned using chemicals or sterilized with optional UV lighting.


Safety

Safety and quality 

A door switch ensures the motor stops as soon as the door is opened. After closing the door properly, the motor restarts. The safety, reliability and quality of our shakers are of personal concern to everyone at Kuhner which is why all our machines are supplied with a 5 year warranty. 


Configuration

Configuration

The LT-X can be equipped with options for CO2, O2,controlled humidity, LED photosynthesis, UV lighting and much more. It is now also possible to integrate measuring data from Kuhner shakers with your company’s own network using Kuhner Insight software together with the NET-60 interface.

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.


O₂ control (PhysOx control)

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.

Visit our poster gallery and find more information on the poster "Oxygen Transport Phenomena in Single-Use Shaking Flasks under Reduced Oxygen Conditions".pdf


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.

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. More.


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

UV lamp

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.


Light shade plate

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".

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.

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


Touchscreen

This option includes a 7-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.


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 or EX size tray. However, with the dual table the shaking speed is limited to a maximum of 200 rpm.

Ausziehtisch

EPFL-table

Are you screening using large numbers of 50ml bioreactors (TPP, Falcon tubes etc.)? Then our new EPFL-table is the ideal solution. This table accepts up to five tube holders, each with a capacity of 24 x 50ml tubes. Each tube holder has its own clamp handle allowing it to be easily taken out of the incubator shaker and put on a clean bench while the other tubes keep on shaking. It’s also possible to shake microtiter plates on the EPFL-table, using Duetz 4-place coverclamps. If you have a Kuhner F-size tray (800 x 420mm), you can also clamp that on the table instead of individual holders. The TabCom Option is not possible with an EPFL-table. The TabCom Option is not possible with an EPFL-table.

An EPFL-table with 4 clamp positions is also available for the ES-X Lab-Shaker.

EPFL-Tisch

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 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.
