The VTA | HSR Diffusion Pump – Complete Jet System is an HSR oil diffusion pump used to achieve the ultra-high vacuum levels required for molecular distillation on VTA VKL and VKS series wiped-film distillation systems. The diffusion pump operates downstream of the rotary vane fore-vacuum pump, boosting system vacuum to the 0.001–0.1 mbar range needed for efficient molecular separation of high-boiling-point botanical extracts. Supplied with LVO 520 diffusion pump fluid.
