GEMINI Twin-Port Sampler
the total flow for four tubes may be up to 1000 ml/min.,
with a maximum of 500 ml/min. through each GEMINI
Sampler if the pump flow rate is adjusted nearer to 1.7
LPM. Keep in mind that this additional load will likely
shorten the expected running time of the sampling pump.
5. While rotameters or other devices may be used for rough
setting of flows, their inherent pressure drop adds to the
tube load. Therefore, use only a soap film device, the DigiCal
5 Primary Calibrator (Part No. 655101) for final flow
calibration. Always have the actual tube or equivalent load
in place during flow calibration.
Remote Sampling
Remote sampling can be accomplished by connecting a remote
sampling line between the pump and the Sampler. The sampling
line should have an inside diameter of 1/8-inch or larger to prevent
loading the pump.
