Question about Peristaltic Pump

Hi openQCM Team,

We have a plan to buy a peristaltic pump. The pumps with fixed speed are cheaper, but I don't know which speed to use.

I want to share this link with you. There are several pumps to choose. They have different maximum PSI and RPM.

http://www.mscdirect.com/browse/tn/Plumbing-Pumps-Filtration/Pumps/Fluid-Metering-Pumps/Peristaltic-Metering-Pumps?intcmp=BcCTA_PDP_PeristalticMeteringPumps_20160520_v1&navid=12104510

Could you please let me know which matches our QCM better?
Or could you please tell me the flow rate range so that I can choose a proper peristaltic pump?

Thank you so much!

    Generally we used a flow rate of about 0.1 ml / min Which causes a frequency standard deviation of about 3 Hz to flow . The maximum flow rate Should be 1 mL / min
    Higher flow rate can cause larger frequency fluctuations around the baseline . But it should work as well, actually it depends on the frequency resolution that you need for your experimental tests .
