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.
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.
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.
The pull-out table is designed for the ISF1-X and ISF4-X incubator shakers as well as the Rack System. This remarkable device makes loading and unloading trays much easier.
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, EX or F size tray. However, with the dual table the shaking speed is limited to a maximum of 200 rpm.
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.
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.
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.
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.
To prevent accidental operation of the controllers, the panel can be protected by a perspex cover.
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 analyzed 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.
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.
