Description

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.

Extra space

Exceptional chamber height means flasks up to 6 liters 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.

Functionality through direct drive

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 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

The LT-X can be equipped with options for CO2, 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 ISIS software together with the NET-60 interface.

Options

Options

Space saving stackable incubator shaker available with options including CO2

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.

backtop Top

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.

backtop Top

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 ten years ago and continues to offer this option.

backtop Top

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.

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.

backtop Top

Illumination unit for photosynthesis (LED)

The ceiling of any Kühner 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.

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 maximize 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.

Perspex cover

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

BPM-60

BPM-60 (Bioprocess Monitoring) is a non-invasive, online measurement of dissolved oxygen and pH in an Erlenmeyer flask.

Continuous, recording of dissolved oxygen and pH

Dissolved oxygen and pH can be easily measured online using the BPM-60. The system allows for one or both parameters to be recorded in the same flask. The values of dissolved oxygen and/or pH can be monitored simultaneously in eight different flasks.

The continuous data logging, compared to conventional sample taking, is automatic and consistent. The recorded data can be analysed to identify oxygen limitation or inhibition and therefore optimize yields in shaken flasks.

Furthermore, the BPM-60 assists in the production of reproducible starter cultures for use in fermenters (see PAT-initiative of the FDA).

Not on battery mode

An integrated socket at the front of the shaking table makes simple data communication and power supply possible without the risk of wiring breaking. With this technology no battery is required.

ISIS software for data logging

Kuhner ISIS Software is capable of data recording. In addition to logging dissolved oxygen and pH it is also possible to record all other shaker parameters such as shaking speed and CO2 concentration. A full audit trail is also stored for each shaker connected.
