Edmund Buhler KM CO2-FL Orbital Shaker with No Drilling
€2.630,00 excl. VAT
The KM CO2-FL is an orbital shaker from Edmund Buhler built to run inside a CO2 incubator without drilling its wall. It reuses the technical base of the KM CO2 but replaces the standard cable with a 120 cm flat ribbon cable, thin enough to pass through the incubator door seal. This makes it the practical choice for labs that do not want to modify their incubator physically. 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 belt-free direct drive gives a softer start suited to sensitive cell cultures and reduces maintenance over the shaker’s service life. Its stainless steel construction withstands the humid, corrosive environment inside a CO2 incubator. The KM CO2-FL suits routine resuspension and mixing of small-volume samples in cell culture work.
Edmund Buhler KM CO2-FL Orbital Shaker with No Drilling
An orbital shaker installed in the incubator, without drilling
The Edmund Buhler KM CO2-FL reuses the design of the KM CO2 orbital shaker, with one key difference: its 120 cm flat connection cable passes directly through the incubator door seal.
No wall drilling is needed to install the external control unit outside the incubator, which simplifies setup and keeps the incubator seal intact.
Belt-free direct drive
Like the KM CO2, the KM CO2-FL uses a direct drive with no drive belt, giving a softer start for sensitive cell cultures.
Stainless steel construction protects the unit from the humidity and corrosive atmosphere inside the CO2 incubator.
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.
- 9 Erlenmeyer flasks of 100 ml, or 2 flasks of 500 ml
- Runtime from 1 second to 100 hours, or continuous
- CO2 tolerance up to 20 percent, humidity 20-95 percent non-condensing
Cabling and power supply
The 120 cm flat cable is the main feature that sets the KM CO2-FL apart from the KM CO2: it passes through the incubator door seal instead of requiring a hole drilled in the wall.
The universal 100-240 V, 50/60 Hz power supply covers most European electrical networks.
Ideal Applications
The Edmund Buhler KM CO2-FL suits the following applications.
- Cell culture in a controlled CO2 atmosphere, without modifying the incubator
- Labs unable to drill their incubator wall
- Resuspension of small-volume samples
- Cell biology and biotechnology laboratories
- Replacing an existing shaker without incubator modification work
Choose the KM CO2-FL when:
- You cannot or do not want to drill your CO2 incubator wall
- You need to install the shaker quickly, without heavy technical work
- You want a belt-free orbital shaker with lower maintenance
- Your cell cultures are sensitive to abrupt starts
- You need external control with an LED display
Buhler Value Proposition
The KM CO2-FL combines a drilling-free flat cable, a belt-free drive, and stainless steel construction suited to the humid environment of a CO2 incubator.
Edmund Buhler has manufactured laboratory shakers in Germany since 1880 and remains a family-owned company.
