Alternatives to the LPMA1250110L pump #14

Naruki Yoshikawa from Tokyo Medical and Dental University asks:

I leaned about your Sidekick at the Acceleration Conference in Toronto last year, and I am trying to build one.

I tried to purchase the pump mentioned in the paper (LPMA1250110L), but I was told it is not available anymore. The provider company suggested using closest alternative LPLA1250625L, but I am not sure if it fits Sidekick. The spec is written here: https://www.theleeco.com/uploads/2021/04/PDS-116-2018-06-LPL-Series-Fixed-Volume-Solenoid-Dispense-Pump.pdf

If you can provide me your opinion about the alternative pump, that is very helpful.

The physical dimensions and electrical characteristics of the LPLA1250625L appear to be the same.

However, it dispenses in fixed increments of 25 uL (instead of 10 uL). It may therefore be useful to modify the code where we convert microliters to pump cycles to account for this.
