A cold trap for condensing and polymerizing residual vapor. The cold trap comprises a containment vessel which comprises a vertical sidewall defining a cylindrical inner surface of substantially constant diameter. Fluidly connected to the sidewall is a vapor inlet line which enters the containment vessel tangentially at a point near the top end thereof such that the vapor entering the containment vessel through the vapor inlet line will impinge against the inner surface of the sidewall and flow in a generally rotational pattern within the containment vessel. The cold trap further comprises a cooling member which is positioned within the containment vessel for facilitating the condensation and polymerization of the vapor.
