2…16 ± 1 rocks/min, adjustable at BIOSTAT
®
RM Control Tower.
1.4.4 Rocking angle
4…10°, ± 0.5°, adjustable at BIOSTAT
®
RM Control Tower.
1.4.5 Temperature control
PLC programmed PID controller built-in the BIOSTAT
®
CultiBag RM 600.
Set temperature is adjusted at BIOSTAT
®
RM Control Tower.
Cooling by ambient air only. No cooling device required.
An electrical resistance heater plate is installed below the rocking table with
a built-in safety temperature switch.
Heating power: One section with 650 W.
Temperature range set tempe15…+44°C, ± 0.1°C.
1.4.6 Measurement of DO and pH
Two reusable non invasive optical fibres for pH | DO are inserted into the respective
sensor ports of the CultiBag RM 600. The optical fiber transmits light of specific
wavelength, to the sensor patch and returns the luminescence response from the
sensor back to the measuring amplifier. The light fibre cables are marked with colours
to avoid insert into the wrong port of the CultiBag RM 600.
– DO (yellow)
– pH (red)
