摘要

Liquid - liquid - micro - extractor for use in the dllme (dispersive liquid - liqiud micro extraction) with an extracting agent, which has a lower density than water, is characterized in that a1. it consists of a glass tube with attached at both ends of the glass threads is that, on one end of a centrally, which has preheated capillary tube, the only minimally projects out from the screw thread and on both ends with screw caps which have a central hole and with an integrated, elastic discs, which consists of a fluoroplastic - rubber - composite material, are sealed.2. the glass tube with the glass threads for the visualization of the phase separation preferably made from clear glass, but also can be made of colored glass.3. the glass tube with the glass threads for the visualization of the phase separation preferably made from clear glass, but also from coloured glass can be composed, in addition, whose surface is silanized.4. it by the use of closure caps can be centrifuged.5. it by the use of magnetic closure caps in auto amp learn can be inserted.6. it by the use of closure caps, which have a central hole and with an integrated, elastic disk made of a fluoroplastic - rubber - composite material, with the cannula be sealed and a liter of the syringe can be pierced.7. the glass tube having at both ends attached glass threads having different dimensions for different sample volumes – as a rule for sample solution of 5 ml to 100 ml of.8. in different dimensions of the capillary tube length and / or of the capillary on the inside by means of knife – as a rule for extracting agent 5 μl to 100 μl.
