tubes in the
rotor A-4-38. At 4,400 1/min you can achieve the following maximum rcf with the various adapters.
To ascertain the maximum rcf for a specific adapter you can apply the following formula as per DIN 58 970:
rcf = 1,118 · 10
–5
· n
2
· r
max
n: rotational speed in 1/min
r
max
: max. centrifuging radius in cm
Example: The 85 ml adapter has a maximum radius of 13.5 cm. At 4,000 rpm a maximum rcf of 2,415 x g is reached.

The continuous run function is set by turning the TIME dial to either above
99 minutes or below 0.5 minutes. The timer displays "oo" to indicate that continuous
running is active. The time is counted upward in minutes.
