VapourSoft® Technology

VapourSoft® Technology

VapourSoft® is our compact energy source containing liquefied gas. Through gentle release of a pressurised vapour, it powers viscous drug delivery with minimal user effort. This technology came about from our proven expertise in metered dose inhaler valves.

The VapourSoft® Advantage

VapourSoft® is used across our range of injection devices. VapourSoft® technology allows greater flexibility in device design compared to what can be be achieved with conventional spring-based auto-injectors.

  • A flexible energy source, simply alter the propellant within a single container format to tailor the performance to drug viscosity, needle, fill volume, and drug delivery time.
  • Provide patients or healthcare professionals with the ability to deliver highly viscous drugs with ease
  • Soft start delivery mechanism reduces impact, making it ideal for glass primary containers
  • Constant pressure profile allows lower peak forces than conventional spring-based auto-injectors
The VapourSoft® canister that drives drug delivery by using liquefied gas

The VapourSoft® canister that drives drug delivery by using liquefied gas. Bespak has a long history of developing metered dose inhaler (MDI) valve technology for liquefied gases.

VapourSoft® Technology in syringe stopper

Injectable drug is smoothly delivered by the syringe stopper being propelled though direct pressure application to the stopper or through a plunger rod.
