4.4 Determination of sample flow rate
The separation characteristics with respect to the sample flow rate by this continuous flow rotor
are given in Fig. 15. Determine the flowing in rate of the sample to be separated referring to Fig. 15.

4.5 Lubricating unit
The lubricating unit is provided with lubricant oil supply mechanism and waste oil recovery
mechanism necessary for rotor operation. It further incorporates with safety features which
detect malfunctions of lubricant or cooling water.
Respective description follows:
(1) OIL
The lubricant oil supply mechanism consists of oil filter and mechanical pump. Turning on the OIL
switch operates the mechanical pump, Lubricant is delivered from the OUT connector and
returns to the OIL bottle through the IN connector. The oil level in the OIL bottle is becoming the
half of the bottle, replenish. The OIL switch also serves as a safety feature actuating switch. If
lubricant stops flowing with the OIL switch ON, the TROUBLE lamp comes on, it inform in the
buzzer sound.
(2) WAER
The cooling water supply mechanism consists of low temperature circulation water bath
connected to the lubricating unit and tubing. Cooling water is delivered from the OUT connector,
and returns to the low temperature circulation water bath through the IN connector. The WATER
switch also serves as a safety feature actuating switch. If cooling water stops flowing with the
WATER switch on, the TROUBLE lamp comes on, it inform in the buzzer sound.
