Superatmospheric cycles&colon; achieved with a vacuum pump. These are a small rotary vane pump, similar to some forms of vacuum pump. This drives off gases, which are removed by continued operation of the vacuum pump. The predecessor to the vacuum pump was the suction pump. A vacuum is initially created by connecting a closed container to a vacuum pump. The adapter 10 has a connection 9 that may be fitted to a vacuum pump. Any evaporation system includes a vacuum pump. Another technical invention is the vacuum pump. Liquid nitrogen is extensively used in vacuum pump systems. Allow the vacuum pump to run an additional three minutes. The equipment is composed of a tool, a press, an injector, and a vacuum pump. Air is extracted from the closed system with a vacuum pump. A spare mounting pad is included for a vacuum pump. The flow capacity of the vacuum pump is less important than its peak vacuum level. Turn on the vacuum pump and pour the sample into the filter holder.
