5. The peptide can be analyzed immediately on an HPLC or UPLC for purity, or can be lyophilized overnight.
6. To lyophilize, suspend the peptide gel in 1% acetic acid in deionized water then freeze with liquid nitrogen before
placing on the lyophilizer.

Maintenance Procedures

Cleaning
Each vessel position should be cleaned before and after use to prevent cross contamination. To clean a vessel position:
1. Insert a 50 mL centrifuge tube in the vessel tray and lock the tray in position.
2. Insert an empty reaction vessel into the appropriate cleavage position.
3. Turn the vacuum pump ON and rinse ethanol or isopropanol through the reaction vessel.
Do not use DCM to rinse any cleavage positions post-cleavage as this can lead to more frequent seal replacements.
4. Turn the vacuum pump OFF and vent the system by turning the Vent valve knob to OPEN.
5. Remove the vessel tray and discard the wash solvent.
