Prepper Special Instructions:

Check boxes for USB cables

Instructor Notes/Comments Lab goes pretty smoothly. Gas pressures above 220 kPa with break the pressure sensors so start syringe volume at 10 mL and compress to only 5 mL but expand as much as desired. Hot plates can melt the tubing connecting the E-flask to the pressure sensor making them unusable.
