Schlenk Line (High Vacuum Manifold) which is equipped with a 5-port, dual manifold vacuum line and connected with an advanced vacuum system (Edwards oil rotary vane pumps and cryobath) are often suitable for carrying out routine polymerization reactions. With this system, a high vacuum level of about 10-4 mm.Hg can be very easily reached in a short time. This instrument can be used for manipulating air sensitive compounds, especially for performing special polymerization techniques such as controlled/living radical polymerization, anionic polymerization, cationic polymerization, polyhomologation, etc.
