The scene in question is on YouTube
"0:24 - canister being handled, no apparent movement of the anti-matter"
"4:51 - Static closeup of canister, with anti-matter movment"
In an earlier part of the scene, someone is attempting to defuse one of the containers and you can see a glowing blue blob inside the glass as it's handled. This is filmed from a distance, so can easily be an internal light illuminating a shape (possibly in an acrylic block). A momentary closeup shows some movement, but as the container isn't moving at the time this can be standard CGI.
The scene in your screencap above is also static and CGI based - short in length against a dark background, so won't take a huge amount of processing power.
It seems likely that this effect is a mixture of physical and CGI. Physical for the dynamic shots where you can't really see the shape in the canister, and CGI for the static, detailed shots.
