if you are doing NH4 disstilation do you need different glassware . do you run block at a diiferent tem.

This glassware is used for both ammonia and phenol distillation. The only difference in the setup is using the long or short outlet tube. The block temperature setting is the same for both methods.

For phenol distillation, you must pierce the septum during digestion. Are these septa for one use only?

These are resealing septa. They can be used over multiple distillations.
