SBM/SS-X (Rack-Shaker)


Extendable rack system with integrated shaking units suitable for temperature controlled rooms

Short description

The Kuhner Rack-Shaker SBM / SS-X is a space saving shaker system designed for environmental rooms, laboratories and corridors.

Performance characteristics

+ Integrated shaking system with racks and shaking units
+ Robust rack system
+ Ideal for temperature controlled rooms, laboratories and corridors
+ Each shaking unit has its own direct drive
+ Low heat loss with energy efficient drive system

Flexible, integrated system

Up to four shaking units (SS-X) can be incorporated into a single rack. The robustly built rack system ensures the shaking units run quietly. The rack system is designed and constructed for maximum flexibility, can be adapted to fit almost any room and is easily extended. The configuration of the shaking units can be altered at any time with little effort. Each shaking unit is fitted with a speed controller and operates independently. Users are able to choose either orbital or linear motion as well as a suitable shaking diameter for each unit.

Ideal solution for temperature controlled rooms

The rack system is suitable for use in temperature controlled rooms. Racks and shaking units are made of stainless steel with hermetically sealed electronic parts.

Low energy consumption – low heat generation

The Kuhner drive emits very little unwanted heat which is an important factor when using the rack system in temperature controlled rooms. The low energy consumption of the drive means low heat generation.

Pull-out table

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.

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 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 Rack-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.


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 (TabCom option) 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.


Kuhner Insight software for data logging

The Kuhner Insight 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.


  • Further information can be found under add-ons.


The TabCom option from Kuhner consists of a cable for power and data with the connection port integrated in the shaking table (see pictures below). A cable guide prevents the cable breaking and ensures secure data recording. Online measuring technologies offered by Kuhner that use TabCom include BPM-60 (pH, dissolved oxygen) and RAMOS (OTR, CTR). The flexibility of TabCom means other measurement systems can be easily integrated.

Universal tray FU

Order number: SM3003

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.


F-tray (800 x 420 mm) with fixed clamps

The clamps are riveted onto this tray and cannot be removed. It offers maximum stability and will often hold a larger number of flasks than an universal tray. These trays are available in a variety of flask clamp sizes from 25 to 6000ml.

F-tray for microtiter plates

Kuhner has designed trays specifically for microtiter plates. Handles at the front of the tray open and close the special clamping mechanism allowing plates to be loaded and unloaded. Trays of different heights (22, 47 and 77mm) allow the
stacking of up to four microtiter plates. The tray is suitable for all types of plates (deep well, low well, 24, 48 and 96 well).


Order number

  Description Number of microtiter plates
SM3503.22 F-MT.22 24 - 48

F-tray with pins

Kuhner has designed a new F-size tray (800 x 420mm) which is ideal for cell culture. The F-V5000/7 tray allows parallel shaking of 7 x 3L Corning Fernbach culture flasks, 7 x 5L Corning Erlenmeyer flasks or 7 x 5L Thomson Optimum Growth flasks. Flasks are held in position by pins and are easily placed on the tray and removed just as quickly.

This tray has been designed for easy cleaning and efficient handling of samples.

F-tray with rubber mat

Order number: SM3603

The whole tray is covered with a rubber mat and is particularly suitable for
shaking containers at low speed (e.g. blood bags).


F-tray with sticky strips

Order number: SMX350001

A tray fitted with sticky strips is especially useful for flasks shaken at low speeds (up to 200 rpm). The flask is placed directly on the sticky strip without the need for any other support. Flasks of all sizes can be used. Sticky strips are available individually or in sets and can also be supplied already fitted to a tray. The F-size tray accepts eight strips.


F-tray with support bars

Order number: SM4130.6

This tray offers an alternative to both clamps and sticky mats and is ideal for tall containers. The tray is covered with a rubber mat and has an upright at each corner. The F-tray is fitted with six cross supports. These support bars securely clamp containers.


F-tray for separating vessels

Kuhner has also designed a special tray for shaking separating vessels. This very flexible tray can take vessels of various sizes. It is also possible to add a second layer and double the capacity. Movable retaining rods allow vessels to be installed easily.

Order number

F-tray for centrifuge tubes

Order number: SM3805

The use of centrifuge tubes (e.g. 50ml Falcon tubes and TPP 50ml) in cell culture screening is well established. This F-tray has a capacity of 120 x 50 ml centrifuge tubes (5 racks of 24).

Holders for 600ml TPP tubes are also available.



Order number: SMX1672

The Rack System can be fitted with a shelf as an alternative to the shaking units, which allows cultivation in petri dishes.

Kuhner Insight Software

The user-friendly Kuhner Insight software was developed for supervision, monitoring, and recording of data. The software is easy to operate


Kuhner shakers are equipped with a CAN-bus. CAN-USB, CAN-Ethernet, EMI-60 and NET-60 are all well established interfaces.
