Edmund Buhler KM 2 Akku Battery-Powered Orbital Shaker
€2.091,00 excl. VAT
The KM 2 Akku is a battery-powered orbital shaker from Edmund Buhler, built for environments without accessible mains power. It suits labs that need to place a shaker inside a refrigerator or a standard incubator, outside of CO2 incubators. Its internal 12 V, 7 Ah battery gives a minimum runtime of 40 hours after roughly 10 hours of charging. The unit can also run on mains cable, continuously, for up to 99 hours 59 minutes. Its 200 x 295 mm platform holds a 2 kg load and covers a speed range of 5 to 220 rpm in steps of 5. The KM 2 Akku particularly suits small volumes, with load examples up to 20 flasks of 10 ml. It reuses the mechanical base of the KM 2 while adding the runtime needed for enclosed-space use.
Edmund Buhler KM 2 Akku Battery-Powered Orbital Shaker
A self-contained orbital shaker for fridges or incubators
The Edmund Buhler KM 2 Akku is the battery-powered version of the KM 2 orbital shaker. It is built for situations where a mains socket is not accessible or not permitted, such as inside a refrigerator or a standard incubator.
The supplied mains charger recharges the battery and, when needed, can also run the unit continuously on cable.
Battery and runtime
The internal 12 V, 7 Ah battery gives a minimum runtime of 40 hours after a full charge of roughly 10 hours.
On mains cable, runtime ranges from 0 to 99 hours 59 minutes, or continuous.
Platform and load capacity
The 200 x 295 mm platform holds a maximum load of 2 kg and runs from 5 to 220 rpm in steps of 5, with a 20 mm stroke.
- 20 Erlenmeyer flasks of 10 ml, or 12 flasks of 50 ml
- Ambient operating temperature from 4°C to 45°C
- Universal charger power supply, 100-240 V, 50/60 Hz
Weight and footprint
With its battery and charger, the KM 2 Akku weighs 10.5 kg, with the same footprint of 250 x 415 x 145 mm as the standard KM 2.
Ideal Applications
The Edmund Buhler KM 2 Akku suits the following applications.
- Shaking inside a refrigerator
- Shaking inside a standard incubator, outside CO2 units
- Sites without accessible mains power near the shaking position
- Small sample volumes, up to 50 ml per vessel
- Biology and biochemistry laboratories
Choose the KM 2 Akku when:
- You need to shake samples in a fridge or incubator without a mains socket
- You want a self-contained orbital shaker on battery power
- Your sample volumes are on the small side (10 to 50 ml)
- A minimum runtime of 40 hours fits your protocol
- You want to keep the option of running continuously on mains power
Buhler Value Proposition
The KM 2 Akku combines the compact KM 2 orbital shaker with an internal battery, for shaking samples where mains power is not available.
Edmund Buhler has manufactured laboratory shakers in Germany since 1880 and remains a family-owned company.
