We required a timely delivery mechanism for dry ice which we use for chilling samples in an alcohol bath. This device allowed us to perform impromptu sample tests without losing an hour in purchasing dry ice. Cost recovery was less than three months of labour transit time.
Pros: Immediate delivery of dry ice flakes for lab environment
Cons: Bag has limited lifespan
