Develop a protocol for degassing a solution with a balloon
Fritted 24/40 500mL Erlenmeyer flasks
3-way stopcocks (Kimble Chase) (420163-4503)
Needles to connect to balloon (Stainless steel 304 syringe needle, non-coring point, 10inch 16 gauge
Needles to vent container: 27 gauge, 25 gauge, 23 gauge, 20 gauge, 18 gauge, 16 gauge.
N2 pressure to fill the balloon -- 100kPa
Suba-Septa (Ace Glass 24/40 9107-143)
The goal is to have a system that degasses a solution from N2 in a balloon.
All gauges of needle have kept air flow going for a full 20 minutes. See picture below for setup.
This area is for any observations or conclusions that you would like to note.
