Solvent Purification System (SPS)

On an everyday basis, each solvent should look like figure 1. Please check the argon tank to

ensure that it is above 500 before using. If it is below 500, notify those in charge and it will

be replaced by one of them. In addition, make sure the gauge (located on the left side) on

the SPS is between 10 -15.

Figure 1 – system is open to argon Figure 2 – system is closed

When a solvent flask is empty:

1. Close the system by turning the bottom knob to its horizontal position (figure 2).

2. Loosen the metal clamp and remove the flask. Make sure that you place a glass cover

where the flask was.

3. Remove the syringe cap piece (throw in trash) and black knob screw.

4. Wash the flask with acetone.

5. Screw on new syringe cap piece and re-attach black knob screw.

6. Flame dry (under vacuum) for approxiametly 10 minutes. Make sure you flame dry the

small glass joints of the flask as well. Before turning off your vacuum, close the black

knob screw fully to ensure the largest bulb of the flask remains under vacuum.

(*CAUTION* - the syringe cap piece will melt, so be careful while flame drying)

7. The flask may now be attached to the SPS, ensuring the metal clamp is screwed tightly.

8. Switch the top knob to VACUUM (figure 3).

9. Open the system by turning the bottom knob to its vertical position (figure 4) and leave

for a minimum of 30 minutes. (*NOTE* - if you are replacing more than 1 flask at a

time, then it will need to vacuum longer)
