NanoSoft's custom designed ethane condenser tightly interfaces with Metal Spider (#47000-702) as well as the spider from the FEI/Thermo Fisher styrofoam dewar set. The user places the spider normally and inserts the condenser. The user does not need to handle an ethane nozzle and can instead focus solely on the liquid ethane level, using just one hand to control ethane flow rate, making the process much easier and ergonomic. Furthermore, the condenser should reduce wasted ethane gas and the time required to fill the cup with liquid ethane.
