The Lab-Shaker LS-Z, just like its predecessor
LS-X, is a sturdy benchtop shaker designed for continuous and maintenance-free
operation. The LS-Z is part of a new 3-in-1 modular system to provide maximum
flexibility to our customers. The shaker is the perfect starter model, e.g.,
for universities or start-ups. It can be used for cultivation of microbial,
plant and animal cell cultures. Furthermore, the LS-Z is well suited for the
integration into liquid handling systems (e.g., Tecan, Hamilton,…) and other automated
laboratory processes.

Shaking diameter
Dr. Shakers Helpful Hint N°4 explains what the shaking diameter
is and how you can determine the shaking diameter of your lab shaker.
Find information on the importance of the shaking diameter for biological cultivations in our Shaking Technology Forum: Why is the shaking diameter important?
The LS-Z comes with three options: benchtop only/stand-alone, combinable with incubators or liquid handling systems from other manufacturers, or combined with the new Kuhner Kelvin+ incubator for temperature control. The LS-Z shaker unit has a very small footprint, 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.
LS-Z shaker unit tolerates an ambient relative humidity of
up to 90%
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.
The LS-Z shaker accepts 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.
Due to hygienic design, the drive is also protected from any spills.
The LS-Z is well suited for the integration into liquid handling systems and other automated laboratory processes. The lab shaker can be equipped with the flexible Kuhner interfaces (such as the Net60 interface) to connect the system very easily to standard process control systems (e.g., Siemens, Emerson, …). With these interfaces, also the control of the shaker setpoints can be realized (automation of the system). Additionally, the LS-Z has a precise stop position, which is for instance crucial for the integration into a liquid handling system.
As with all Kuhner products, the LS-Z is a cost-effective investment in quality backed with a five-year warranty.
We subject all our shaking machines to an elaborate final test before delivery and send the test protocols to our customers.

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 (420 x 420 mm), EX (500 x 420 mm) or F (800 x 420 mm) size tray.
The dual table is available with a fixed distance between the two levels of either 120, 160, 180, or 200 mm. At the maximal distance of 200 mm the lower level accepts 125 mL, 250 mL, and 500 mL Erlenmeyer shake flasks.
However, with the dual table the shaking speed is limited to 200 rpm at a shaking diameter of 50 mm (all other maximum shaking frequencies, dependent on the shaking diameter, can be withdrawn from the LS-Z manual).
Do you perform screenings with a large number of 50 ml bioreactors (TPP, Falcon etc.) or microtiter plates? Would you like to shake different cultivation vessels on the same shaker and be able to change the composition quickly and easily? Then the Kuhner EPFL-table is the optimal solution for you. The shaker table has 5 individual clamps, so that 5 different holders or EPFL universal trays can be clamped. By opening a clamp, a single holder or universal tray can be easily removed from the incubator shaker and processed under a clean bench while the remaining holders/trays keep on shaking.
The EPFL universal tray can be equipped with clamps for Erlenmeyer flasks, Schott laboratory bottles, test tube holders, microtiter plates or customer-specific holders. Rearrangement of these clamps and holders is quick and easy. The universal tray can also be equipped with sticky strips. Sticky strips are used to fix shake flasks or other equipment on shaking trays. They offer easy handling and flexible positioning of different sizes and shapes of shake flasks and other vessels.
Special holders for microtiter plates, 50 mL centrifuge tubes (Falcons) and 600 mL reaction vessels are also available for the EPFL-table.
Instead of 5 individual holders, a large Kuhner F-tray (800 x 420mm) can also be clamped onto the shaker table.
For the smaller (incubator) shakers from Kuhner, correspondingly adapted EPFL-tables with 3 or 4 clamps are available (LT-X: 3 clamps, LS-Z: 3 or 4 clamps).

AerationSystem and FlowCon provide the ideal system for carrying out cell/stem cell cultivations in a simple, fast, and inexpensive manner.
Lab shakers in
temperature-controlled rooms and incubator shakers without humidity and CO2-control
can be equipped with the AerationSystem and FlowCon to easily implement humidification and a controlled
gas composition for carrying out cell cultivations (e.g., CHO, HEK cells…) in
shake flasks.
The FlowCon is a stand-alone gas mixing device and provides a precise gas composition and flow rate. Simultaneously, the AerationSystem (consisting of GasDivider and special shake flask caps) humidifies and distributes the gas flow evenly to the connected shake flasks. Evaporation losses from the shake flasks are significantly reduced, which is particularly advantageous for very long cultivation times (such as cell culture processes) and contributes to successful cultivations. Another advantage is that opening the incubator door does not affect the gas composition in the shake flasks when they are connected to the aeration system.
By controlling the composition of the inlet air with the FlowCon, it is not only possible to supplement CO2 but also to increase or reduce the concentration of oxygen (O2) or implement anoxic conditions using nitrogen (N2). This control of gas compositions allows for a variety of different applications, including stem cell processes for gene therapy or cultivated meat that require a physiological oxygen concentration at 5% O2 or anaerobic cultivations in a nitrogen atmosphere.
The patented Kuhner GasDivider humidifies the mixed, dry gas flow provided by the FlowCon and distributes it precisely and evenly across the attached shake flasks, independent of shake flask type, tube length and any filters in-between. As the GasDivider is placed on the shaking tray of the (incubator) shaker, the gas flow is also perfectly adapted to the temperature of the incubator shaker or temperature-controlled room.
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.
E & F size 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.
