• Pioreactor development log #5

    ⭐️ One of our goals with the Pioreactor is design it such that you don't need to be a biologist,  or an electrical engineer, or relevant for this a...
  • Pioreactor development log #2

    ⭐️ This week, we added some updates to the user-interface, a new data-viz, and did our first tests comparing heated and non-heated effects on grow...
  • Replication, variance, (and growth rates) in Pioreactors

    One important property we wanted Pioreactors to have was low variance between units. That is, one Pioreactor should be interchangeable with another...
