IMPROVED VERSION !!!! RUBBERISHED CORK DOES NOT CRUMBLE
We all know how hard it is to prepare a butterfly or a moth on which it wings went some killing fluid has they are all attached and ruined
These cork stoppers are made for you , they allow you to kill moths, butterflies and other insects without getting them in direct contact with the killing fluid and make their wings get wet .
Cork stoppers for killing tubes with holed flipcap tube in the middle, easily reclosable and with pressed cotton roll inside . Collect an alive moth or butterfly , put it inside the tube, close with the cork stopper then put ethyl acetate or Ammonia in the small tube and simply close the cap .
The killing fluid vapors, will get into the tube in a few seconds and ONLY VAPORS WILL BE IN THE TUBE NOT ANY FLUID allowing the moth wings to stay perfectly dry . Once you drop the killing fluid into the tube, the cotton inside will allow the fuild to stay wet and last for at least 30-40 minutes or more so you can kill many moths with the same fluid .
The sizes of these cork stoppers are suitable with our 45ml push cap tube and 50ml screw cap Falcon type tubes in our store
