Securing the top lid

On the Niskin water sampler you must pass and secure the wire through the handle. This method will keep the top lid in the correct position, so it will not get hit by the drop messenger during the release.

The latex rubber band for closing the lids has a limited warranty and direct exposure to sunlight for a longer period will shorten durability.
