ISF1-Z incubator shaker - the perfect solution for shaken cultivation processes
The ISF1-Z incubator shaker is suitable for applications in laboratories, research centers and production facilities. The ISF1-Z complies with GMP (good manufacturing practice) requirements and regulations. It offers a large shaking capacity with a small footprint and many features allowing straightforward, safe handling of any culture or product. The incubator shaker is applicable for microbial, plant, human and animal cell cultures.
Performance characteristics of ISF1-Z models
• Large shaking capacity with small footprint
• Hygienic design according to DIN EN ISO 14159
• Improved direct drive: stronger, higher shaking frequencies, very long lasting
• Up to three machines can be stacked without additional components: incubators ISF1-X/W and new ISF1-Z mixable in stack
• Flexible and retrofittable: all options and accessories applicable
• Fast, direct information through parallel and clear display of all process parameters
ISF1-Z Models
• The ISF1-Z incubator shaker is available in three different models: ISF1-Z, ISF1-Z EcoDew and ISF1-Z Peltier. Each model provides distinct features and is additionally available with CO2 control for cell culture processes.
• The ISF1-Z is the basic version of Kuhners stackable incubator shaker with temperature control (heating).
100% stainless steel for easy cleaning
• The ISF1-Z is available in a 100% stainless steel finish. It can either be painted white or have a processed stainless steel look. Take a look at the video to see the advantages of having stainless steel inside and outside the shaker.
Quality
• The improved maintenance-free direct drive of the ISF1-Z is stronger, offers higher shaking frequencies and has a longer lifespan than ever. It guarantees accurate control and low energy consumption/heat dissipation even at high speeds. Kuhner’s direct drive system and the newly designed shaking table allows the shaking diameter to be changed at any time – quickly and easily. Different fixed shaking diameters (3, 6, 9, 12.5, 19, 25, 50, 70 mm) are adjustable. And even a stepless adjustment is available as an option.
• All ISF1-Z components are designed for durability and reliability. A Kuhner shaker is a cost effective investment in quality backed with a five year warranty.
Hygienic design
• The ISF1-Z is made of stainless steel inside and outside for easy and fast cleaning. The hygienic design complies with GMP requirements. The interior was designed according to DIN EN ISO 14159. It has rounded corners and a drain at the back for quick removal of any unwanted liquids. The direct drive system is completely covered and therefore protected from spills. The incubator chamber can be cleaned with chemicals or sterilized using optional UV lighting.
A system that grows with your needs
• Up to three ISF1-Z incubators can be stacked providing more shaking capacity without taking up more floor space in the lab. Stacking is a simple procedure without the need for special tools or stacking kits. Each machine operates independently. The ISF1-Z incubator shakers are mixable in stack with ISF1-X/W incubators.
Options, accessories, and more
• Numerous options and accessories are available for the ISF1-Z incubator shaker to fulfill any need of our customers regarding cultivations in shaken bioreactors. Moreover, all accessories are interchangeable between the new ISF1-Z incubators and its predecessors ISF1-X/W. The ISF1-Z offers even more interior space than its predecessor ISF1-X, e.g. to accommodate particularly big shake flasks. The ISF1-Z has clearly arranged displays on the front side (e.g. for shaking speed) with color change and an acoustic signal when an error/alarm occurs.
• Additionally, a fix or a tilting touchscreen version with our Kuhner Insight software is available. Serial interfaces (e.g. CAN) are arranged on the front side and the sensors in the inside are also easily accessible for a fast and comfortable work flow. The interior LED light is a color neutral light with low energy dissipation.

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
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.
• 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, 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.

Large incubator shaker with a minimal footprint and up to five independent shaker units
The Kuhner ISF4-X incubator shaker offers large shaking capacity with temperature, humidity and CO2 control all available. The shaker cabinet can incorporate four or even five independent shaking units which are height adjustable. The shaking diameter and speed of each unit can be individually selected. Standard diameters are 12.5, 25 and 50 mm. Other shaking diameters are possible.
Performance characteristics
• All stainless steel interior
• Large shaking capacity
• Easy access to contents
• Each shaking unit has its own direct drive
• Door heating, with controlled humidity
• Guaranteed quality
When designing the ISF4-X special emphasis was placed on reliability and durability. The high quality of Kuhner shaking machines is backed with a five year warranty.
• Safety and convenience
The large door opening of the ISF4-X allows easy access to the shake flasks inside. The doors are fitted with a safety switch to ensure shaking stops when the doors are opened.
The large windows allow a clear view of incubator’s contents. The entire ISF4-X chamber is made of stainless steel making sterilisation with chemicals possible.
• Energy saving operation
The highly efficient direct drive system means economic low power consumption and the cooling system also operates with energy efficiency.
• Electrical protection
Automatic supervision of the mains voltage protects the shaker and in the event of a voltage spike the unit disconnects from the mains. The machine resumes operation at the set values once power is restored.
