Solvent Purification

  • Use a RBF (24/40 mouth) that’s been dried in the oven.
  • Allow to cool to room temperature. Bring a septa and cork ring.
  • Flip switch on pump to left of purification system – allow to equilibrate for about 15 sec.
  • Attach RBF to dispenser, clamp if necessary.
  • Follow BLACK arrows first, turning dial to “evacuate”, and then “refill” 3x. **Allow more time for a larger RBF – Far right gauge moves, look at this to observe changes in emptying/refilling**
  • Next follow GREEN arrows, turning dial from “evacuate” to “dispense." 
  • Turn knob above dispenser to fill flask with solvent. Close when finished, and turn dial to “Refill”.
  • Disconnect RBF, cap with septa.
  • Turn off pump.
  • Fill out journal with last name, amount of solvent, and total solvent (add amount you took from the last amount totaled of that particular solvent).
