在DNA提取过程中,一般实验室的操作主要是通过离心机完成,实际上还有另外一种利用带luer连接器的真空歧管(vacuum manifold)完成抽提的方法,其特点如下:

位于真空歧管上的真空释放阀,用于在供料轮上的预定排出位置从袋子向空腔内排出颗粒材料;
A downstream vacuum relief (48) on the vacuum manifold functions to discharge particulate material from the pockets into the cavities at a predetermined discharge location on the wheel.
活塞主要因进气歧管真空度的变化而在活塞腔内上下移动。
The piston moves up and down in the piston chamber primarily in response to changes in intake manifold vacuum.
这是因为当发动机熄火时,进气歧管冷却而产生轻微的真空。
When the engine is shut off, the intake manifold cools and a slight vacuum forms as a result .
