It comes with a transfer guard the blue piece at the top that is removed before inserting the reservoir into the pump. This assists with pulling the insulin from a vial into the reservoir.

My pharmacist advised that the bottle was good for up to 60 days after opening as long as its kept cool. I find no drop off of effectiveness going to 60 days. I believe it is a waste to through it out after 28 days because I still have over 80% of the bottle left after 28/30 days. As stated, and from what I was told. all insulin should be descarded after 30 days of first use.
