Rose Entomology aspirators use a revolutionary new design that incorporates a machined delrin lid with a rubber O-ring seal. This design prevents insects from crawling between the stopper and the sides of the vial, eliminating the accidental crushing of specimens. Additionally, the design allows the use of standard size plastic or glass vials that are readily available from several suppliers. Insects are always at least 12 mm from the open end of the vial allowing enough time to remove the lid and replace it with a cap before specimen shave a chance to escape.
Other features of the Bug-Vac aspirator include thin-walled brass tubing and a large internal filter using 120 mesh stainless steel screen (finer screen on special order). The large diameter of the screen allows for excellent air flow and eliminates screen plugging.
Optional: An in-line air filter which prevents virtually all particles from reaching your mouth. Each unit comes packaged with:
- four plastic vials and caps (or one glass vial for sizes 0 and 00)
- a length of vinyl tubing
