Glovebox is smart, but not strictly necessary.

If you design the lids right, and use a clean needle- you can inject in room air. Think about getting an injection in the hospital- the master solution was prepared in a laminar-flow hood inside a clean room in the pharmacy- but the nurse injects your skin right there in a dirty room.

It's a similar situation with PF Tek. The vendor needs a clean and sterile environment to prepare your syringe, but the actual injection of the jars isn't as finicky.

But a glovebox really is a good idea.
