Vial Storage System for Tasting

My tasting group & I are seeking to utilize small, 2-3 oz vials to extend the lifespan of our wines for the purposes of Advanced-level tasting. We have Coravin access but we'd like to extend our tasting windows with wines beyond what a Coravin can offer. We've heard of higher-level candidates using systems like this in the past, and we are looking for assistance getting it off the ground for ourselves. Does anyone have experience utilizing a system like this? Are there specific types of vials/closures that you have found success/failure with? Is it possible to create a vacuum for long-term (4-6+ months) storage inside the vials? Are there obstacles/challenges we might not be foreseeing in getting this off the ground?

Thank you in advance for any help/guidance you can provide.
