b.Use the same cylinder for both
c.Mix them in a single drum
d.Skip identifying the second refrigerant
Explanation
Between refrigerants, evacuate the recovery machine and hoses and use a separate, dedicated cylinder for each refrigerant to prevent cross-contamination. Reusing a cylinder or skipping identification can create a mixed batch that cannot be reclaimed. Clean separation preserves the refrigerant's value.
