Minimum Flow Rate of the Pump

[yamada]

Hello, we would like to achieve a very low flow rate for the bioreactor.
According to the website, it states:
“Maximum flow rate: 1.0 ml/s, lower flow rates achieved by duty cycling pump on/off.”
If you happen to know the minimum achievable flow rate and the smallest increment (in μl/min) by which the flow rate can be adjusted, I would greatly appreciate your guidance.

Hello,
In essence you could make it arbitrarily slow by (for example) turning it on only once every 10 minutes, 1 hour, day, year…. so it is difficult to answer.

In practice you can do somethin glike 0.5ml/minute just using the integrated once-per-minute turning it on for 0.5 seconds every minute.
If you wanted to go slower than this you could make it do one aditionl every 10 minutes, so it would be 0.05ml/minute but delivered at 10 minute intervals.
You can extend this out indefinitely but the caveat is you end up with fairly irregular dosing (i.e. it is NOT continually feeding liquid but at a very slow rate)
hope this makes sense
