Vaccine and medicine storage had a simple but expensive weak point: glass bottles broke. Every breakage risk added packaging, careful handling, loss, and cleanup to a workflow that needed reliability.

A Smithsonian record for a 64-ounce Nalge bottle used by Connaught Labs to store Salk and Sabine polio vaccine concentrates notes that plastic bottles of this sort entered the market in 1965 and were less likely to break than glass, lowering costs for vaccines and medicines.

The mechanism was humble but powerful. A blow-molded plastic bottle could act like familiar labware while changing the economics of failure. Modern Nalgene HDPE lab bottles keep the same logic: chemical resistance, uniform walls, low leachables, and leakproof linerless closures.

The clever move was not adding a safety accessory to glass. It was removing glass from the bottleneck and letting the container absorb ordinary lab abuse.

Make the lab bottle plastic

The bottle preserved the existing storage-and-cap workflow, so labs did not need a new process.

Plastic attacked breakage directly rather than adding more protective packaging around glass.

Durable standardized bottles could serve storage, shipping, and field handling with one part.

A material swap can be a process redesign when it removes the failure mode everyone had been working around.

Nalgene lab bottles became a durable category across laboratories and later helped the brand move into outdoor bottles. The transferable pattern is simple: when users already trust a format, changing the material can quietly unlock a much larger market.
