EASY-TO-USE AND ECONOMICAL SOLUTION Switch volumes at low cost Interchange vessel volumes (35 ml to over 61) with just one instrument Threaded glass vessel with screw caps ~.. . Setting up is as easy as screwing a cap on the ·4 ; ,f bottle Unique sterility concept Assures a perfect & easy sterility maintenance for a long time Novel non-rotational bio-mixing Produces no vortex which eliminates the need of baffles WHY LAMBDA ELIMINATED HEAD PLATES? LIMITED number of ports REPLACE O-rings before each run setting up ~ & cleaning process ~ EXPENSIVE spare parts CONTAMINATION due to flattening of O-rings during sterilization TIME consuming set-up NEED new head plates ~ (probes, O-rings, nuts..) ~ for each new vessel size ~ DIFFICULT to make tight connection with shallow threads E;1 LARGE VESSEL = high medium cost + downstream cost + long sterilization & cooling time + .. difficulty in disposing infective material
