The bendy straw is convenient for adjusting angles between vial and insect pick-up straw. Since angle of insect pick-up straw is adjustable, insect collecting vial can stay upright, making it possible to keep an insect killing agent (e.g. alcohol) in collecting vial while using aspirator.
Four vials (DP0079-5 and DP0101-2) are included for insect collecting and insect storing use. Vial DP0101-1 is also compatible, which is not included in the package.
NOTE: DP0101-2 and DP0101-1 are not sealed when the cap is on. Do not use them for fluid.
