How have GasPak systems evolved since their inception, and what are some modern improvements?

Initially developed in the 1960s as a cost-effective alternative to manual pumping methods, early GasPak systems relied on water-activated sachets and palladium catalysts. Modern systems, such as the BD GasPak EZ, have streamlined the process by eliminating the need for water and additional catalysts. These improvements result in a safer and more convenient operation, making the systems suitable for a broader range of laboratory applications, including those with smaller sample volumes.
