Owner's manual

The fixed-angle rotor F-35-30-17 can be loaded with 15 ml Falcons

and 15 ml round bottom centrifuge tubes. It is

available in the 10 and 30 position versions. Please use only swing-bucket rotor A-4-38 with round buckets and the

appropriate adapters for centrifuging blood sampling systems.

Before centrifuging the Falcons

, place their plastic adapters in the tube holders. The adapters prevent the Falcons

from

being destroyed. For the centrifugation of round bottom tubes made of Duran

glass, round rubber pads are required to

prevent the tubes from cracking. Make sure a rubber pad is placed under each glass tube before centrifuging.

In order to avoid breakage of the tubes when using centrifuge tubes of glass, polystyrene or similar materials, please

observe the limiting data with reference to endurance specified by the manufacturer.

The maximum load capacity for Falcons

is 20 x 15 ml; for 15 ml round bottom centrifuge tubes 30 x 15 ml. The rotor can

be loaded with a combination of 15 ml Falcons

and 15 ml round bottom centrifuge tubes. The maximum capacity is then

20 x 15 ml Falcons

and 10 x 15 ml round bottom centrifuge tubes.

The specified max. weight of 56 g imprinted on the rotor is the gross weight rating including the tube holder,

adapter, tubes and contents. Always weigh the tube holder and the load together.

A maximum of 24 1.5/2.0 ml test tubes can be centrifuged in rotor F-45-24-11. If the appropriate adapters are used, it is

also possible to load it with 0.2 ml PCR tubes, 0.4 ml test tubes, 0.5 ml test tubes and 0.6 ml Microtainers

Fixed-angle rotor F-45-18-17-Cryo can be equipped with cryotubes (max. diameter 17 mm or 13 mm with adapters) and

sealable centrifuge tubes (max. diameter 16.5 mm or 12.2 mm with adapters). In each of these cases, max. tube length is

50 mm.

Maximum load (adapter, tube and contents) per bore is 3.75 g on rotor F-45-24-11 and 8.7 g on rotor F-45-18-17-Cryo.

When loading the rotors, please make sure that the tubes are inserted in the bores of the rotor opposite one another in

pairs.

To ensure that the rotor is loaded symmetrically, the tubes opposite one another need to contain approximately the same

filling quantity.

Fixed-angle rotors are operated without a rotor lid.
