    • Liquid filter assemblies including an upper sample reservoir, a sample filter and a lower storage bottle are supported by a vacuum base. The base has a vacuum inlet port and, for connection to the liquid filter assembly, a vacuum outlet port. A vacuum is provided through the base to below the sample filter to draw sample liquid through the sample filter into the storage bottle. The base may include an auxiliary vacuum outlet port for connection with additional devices. The bases may be connected from one to another through auxiliary vacuum outlets and the vacuum inlets to make a chain of liquid filter assemblies supplied from one vacuum source. Alternatively, one base may include multiple vacuum outlet ports so that it may support and supply vacuum to a plurality of liquid filter assemblies.
    • 包括上样品容器,样品过滤器和下储存瓶的液体过滤器组件由真空底座支撑。 基座具有真空入口,并且用于连接到液体过滤器组件的真空出口。 通过底部提供真空至样品过滤器下方,将样品液体通过样品过滤器吸入储存瓶中。 基座可以包括用于与附加装置连接的辅助真空出口。 底座可以通过辅助真空出口和真空入口从一个连接到另一个,以形成一个从一个真空源供应的液体过滤器组件链。 或者,一个基座可以包括多个真空出口端口,使得其可以支撑并提供多个液体过滤器组件的真空。
