FAQ Protocol

How much water can it dispense?expand_more
The dispenser can pour from 50ml to 500ml per cycle, programmable in 50ml increments. The pump handles up to 1L/min flow rate.
Is it safe to use with drinking water?expand_more
The silicone tubing included is food-grade. However, for best results, we recommend using it as a learning tool with non-drinking water for demonstrations.
How long does it take to build?expand_more
The complete build takes 4-5 hours. It's one of our simplest kits, making it perfect for first-time builders or classroom settings with limited session time.
