Bühler KM 2 battery-powered mini shaker
The Bühler KM 2 battery-powered mini shaker is a mobile orbital shaker that has been specially designed for laboratory applications where maximum flexibility, precision and reliability are paramount. This device has proven itself to be a versatile and robust tool, particularly in bacteriology, virology and diagnostics. Thanks to its battery operation and sophisticated technical features, the KM 2 Battery is ideal for laboratories that value cordless freedom, compact design and precise results. Compared to similar laboratory shakers, the device impresses with its user-friendly operation, long runtime and stable performance even during continuous operation. Innovative technology for demanding laboratory environments
The circular/orbital shaker is based on the proven technology of Edmund Bühler GmbH and sets standards in the category of mobile laboratory shakers with its features. Its most important technical characteristics help to make a wide variety of laboratory processes - from cell cultivation to reagent preparation - efficient, reproducible and safe.
Key technical features at a glance:
- Circular shaking motion with 8 mm stroke for homogeneous mixing
- Stepless speed control from 30 to 420 rpm - individually adjustable to the application and medium
- Maximum load: 2 kg - ideal for a wide range of vessel types, such as Erlenmeyer flasks, cell culture bottles and test tubes
- Shaking surface: 200 x 295 mm - sufficient space for different vessel sizes
- Battery operation: 2 x 24 V/2.2 Ah, with external charger (100-240 V, 50/60 Hz)
- Dimensions (W x D x H): 220 x 410 x 130 mm; weight: 9.5 kg - compact and portable
- Protection class: IP 21 for safe operation in standard laboratory environments
Other features include a robust housing design for stability, low heat emission (approx. 4 W even at full load) and the option of using the device in laboratory areas with high temperatures and humidity (ambient temperature: 5-40 °C, humidity up to 85%).
Special features and user comfort
The KM 2 battery is particularly notable for its wireless mobility - switching between batteries allows for a high degree of flexibility when changing locations or working under a sterile bench or in incubators, where cables would be a hindrance. The precise, infinitely variable speed control can be intuitively adjusted directly on the device, allowing for quick changes between different shaking requirements. Thanks to its low noise emission, the device remains pleasantly quiet even during continuous operation and does not disturb the working environment.
Compatibility with laboratory standards and safety
Safety and quality standards are consistently adhered to: the Bühler small shaker complies with protection class IP 21 and is therefore protected against dripping water - important for applications involving liquids. The design ensures long-lasting use and reliable functionality under various environmental conditions. All components comply with current laboratory guidelines and are designed to offer consistently stable performance even during intensive routine operation. Typical laboratory applications in practice
The shaker can be used in a wide range of disciplines in the life sciences and diagnostics. Practical examples of applications include:
-
Bacteriological cultures: Shaking and uniform mixing of bacterial suspensions in Petri dishes and flasks, e.g. E. coli cultures.
-
Virological research: Homogenisation of virus preparations and cell lysates for preparation and analysis.
-
Diagnostic routines: Efficient mixing of blood, serum and urine samples with reagents for serological, immunological and molecular biological test procedures.
-
Sample preparation for ELISA and PCR: Uniform mixing of reagents for precise analysis results.
Typical substances used with the device include cell culture media, buffer systems, blood components, reagents for PCR/ELISA, and bacterial and viral samples.
FAQ - Frequently asked questions
How long does it take to fully charge the battery?
The charging time depends on the status of the batteries, but is usually 4-6 hours. This provides sufficient capacity for one shift, and with a second battery, continuous operation is easily achievable.
Can the shaker be operated in a CO2 incubator environment?
The device is designed for use in laboratory environments up to 40 °C and high humidity. For use directly in a CO2 incubator, it is recommended to consult the manufacturer to rule out condensation damage.
How often should the battery be replaced?
The batteries are designed for long-term operation, but should be replaced with original batteries when their performance starts to decline (after several hundred charging cycles) to ensure consistently high shaking performance.
Which vessels can be used?
Due to its generous shaking surface, the device is compatible with various types of vessels weighing up to 2 kg in total, including Erlenmeyer flasks, cell culture bottles, test tubes, microtitre plates and Petri dishes.
Conclusion
With the Bühlers KM 2 Akku small shaker, laboratories get a highly flexible, robust and precise shaking instrument that is characterised by battery operation, user-friendly handling and versatile application options. Its high compatibility with various types of vessels, reliable technology and quiet, continuous operation make this device the ideal choice for all demanding laboratory processes in the life sciences and diagnostics sectors.
