3. Easy assembly with few additional parts

4. Ports work with old needle setup if needed

Overview

This is the cap that is currently given by default from FynchBio as of 25/01/15.

Requires needles, so cannot have a full seal on the vial. Therefore, should be used with caution because of overflow risk.

Assembly

Must be assembled with needles at correct heights before each run.
