The Lab-Shaker LS-Z and the incubator Kuhner Kelvin+ combine approved Kuhner quality in a new modular system to provide maximum flexibility to our customers. The LS-Z, just like its predecessor LS-X, is a sturdy benchtop shaker designed for continuous and maintenance-free operation. Our new Kuhner Kelvin+ is a compact sized incubator with an excellent temperature distribution.

Performance
The in-house designed magnetic drive system of the LS-Z shaker guarantees accurate control and low energy consumption/heat dissipation even at high speeds. The maintenance-free direct drive is long lasting, robust, and economical. Our Kuhner Kelvin+ incubator has a precise temperature control and comes with a very consistent temperature distribution – for reliable and reproducible cultivation processes.
The LS-Z comes with three functional options: benchtop only/stand-alone, combinable with incubators from other manufacturers, or combined with our new Kuhner Kelvin+ for temperature control. The LS-Z shaker will accept loads up to 25 kg and the shaking diameter can be adjusted at any time. There are three standard shaking diameters (12.5, 25 and 50 mm) with others available on request. The LS-Z shaker unit tolerates an ambient relative humidity of up to 90% and features a detachable control unit and power cube. Therefore, the LS-Z is extremely flexible regarding its installation site: it can be placed in any lab incubator or temperature controlled room.
To take up as little work space as possible in your lab, the LS-Z shaker and Kuhner Kelvin+ both have a very small footprint and can thus either be placed under any standard table or lab bench or be used as a benchtop device. The compact Kuhner Kelvin+ has a flat front and space saving door mechanism. The big window provides a good overview of your cultivation vessels even with closed door.
LS-Z and Kuhner Kelvin+ are the perfect
starter set, e.g. for universities or start-ups with limited space and
resources. They can be used for cultivation of microbial, plant, human and animal cell
cultures. For cell culture fermentations, which require a humidity and CO2
controlled environment, LS-Z and Kuhner Kelvin+ are combinable with
the Flask Aeration System by Kuhner.
The LS-Z has a fixed stop position, which is especially useful for automated processes. The integration in a liquid handling system was successfully performed several times already. Due to the flexible Net60 interface, the LS-Z can be controlled by nearly every external software system.
The drive is protected from spills and the Kuhner Kelvin+ incubator can be easily dismounted for cleaning the whole surface or removal of any unwanted liquid. The incubator chamber can be cleaned with chemicals or sterilized.
As with all Kuhner products, the LS-Z and the Kuhner Kelvin+ are cost effective investments in quality backed with a five year warranty.

The light shading plate is easily placed in front of the door window to prevent radiation affecting the contents of the incubator chamber. It protects light sensitive media from UV, artificial and/or daylight. Simply lift up the light shading 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".
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".
LS-Z and Kuhner Kelvin+
can be combined with Kuhner TOM (Transfer-Rate Online Measurement) for the
online measurement of oxygen transfer rate (OTR), carbon dioxide transfer rate
(CTR) and the respiratory quotient (RQ) in up to 16 individual shake flasks.
These data provide a better process understanding and guarantee an informed
process development. TOM is easily installed 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. More.
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.
Microtiter trays are suitable for all types of plates (deep well, low well, 24, 48 and 96 well).
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 user-friendly Kuhner Insight software was developed for supervision, monitoring, and recording of data. The software is easy to operate More.
Kuhner shakers are equipped with a CAN-bus. CAN-USB, CAN-Ethernet, EMI-60 and NET-60 are all well established interfaces. More.
A stacking adapter allows to stack two LS-Z with Kuhner Kelvin+.
Above the shaking tray of shaker, a fixed shelf can be placed inside the Kuhner Kelvin+ incubator. This can be used for non-shaken experiments and cultures, e.g. T-flasks with animal cell cultures.
The light shading plate is easily placed in front of the door window to prevent radiation affecting the contents of the incubator chamber. It protects light sensitive media from UV, artificial and/or daylight. Simply lift up the light shading plate to look at the cultures without opening the incubator door. When light protection is no longer required, the plate is easily removed.
