While using popular aquarium test tubes we noted with disappointment, that when shaking to mix test solutions with water sample, drops of the corrosive mixture ended up on our fingers and the floor. This led us to source leak-proof caps, so that keeping our aquarium water in check does not mean exposing our skin to highly toxic chemical solutions nor having it splash the bench-top and floor. Each tube is hand calibrated and marked and while the hardworking team in India get it right most of the time, the occassional tube turns up with a mark that's slightly off. For this reason, and given the neck of the tubes are narrower than the API tubes (to facilitate the screw cap) we advise using a syringe to dispense water into the tubes.
