In this work we present a novel device - Laminar Co-Flow Tube (LCFT). A detailed description of the device can be found in Travnickova et al. (2018). The turbulent mixing unit is here replaced by a set of two coaxial tubes which introduce nucleating vapours into the chamber in a laminar co-flow. The LCFT was tested on a H2SO4 - H2O
system whose vapours were saturated to N2 carrier gas in separate saturators. Because the water vapour stream surrounds the stream with sulphuric acid vapours, it
prevents the loss of sulphuric acid or the droplets on the wall of the device. Resulting number of droplets larger than 1.2 nm is determined by PSM (A11, Airmodus).
