Combating the Covid-19 pandemic is at the top of the global agenda. Around the world, efforts are being made to supply the population with vaccine as quickly as possible. But providing around 8 billion doses – at least one for every person in the world – is no easy task. Glass vials are a crucial factor in the delivery of the billions of doses of vaccine. About 50 billion of them are produced worldwide every year. Currently the producers of the vials are massively ramping up their production so as not to become the proverbial bottleneck in the supply chain. However, medical-grade vaccine vials are not standard glass tubes. Whether rolled-rim bottles, threaded bottles or ampoules, they are all made of the special glass borosilicate and require customised production lines. Any interaction between the container and the liquid inside must be prevented, as any chemical interference could affect the vaccine. Even the smallest scratch, crack or fissure can render an entire batch unusable, contaminate the line during the filling process or even lead to a machine standstill.
