在植检业务中,常常需要做线虫的分离工作。无论是贝曼漏斗法还是浅盆法,最终都要将线虫从浸提液中取出。通常,从溶液中取出线虫是用针挑(如竹针、解剖针、毛发等)或用吸管吸。对于活的线虫,由于线虫在不停地运动,因此,用针挑法分离难度高、效率低。对于加热致死的线虫,由于虫体僵直,故用针挑法常常难以奏效。用管口拉细的吸管吸取线虫,虽然分离效率较高,但当浸提液含有大量杂质时,常在吸入线虫的同时吸入大量杂质 In the phytosanitary business, often need to do nematode separation. Neither the Beman funnel method nor the shallow basin method eventually removes the nematodes from the extract. Normally, removal of nematodes from solution is by needle pick-up (eg bamboo needles, dissection needles, hair etc.) or by pipette. For living nematodes, nematodes are constantly moving, therefore, the needles are highly difficult to isolate and inefficient. To heat the dead nematode, it is often difficult to pick the needle because of its rigidity. Pipette fine tube pipette nematode, although the separation efficiency is high, but when the extract contains a lot of impurities, often inhaled nematode inhalation of large amounts of impurities
