3D printed guides for Neptune reagent bottles. Inserts into the cap of your Trident reagent bottle lids and keeps the sample tube perfectly vertical. Prevents the tube from going askew and pulling in air when reagent is low and giving false readings. Wider opening at the top to accommodate the rubber tubing/metal tube, with a narrower opening at the bottom to secure the metal tube. Vent hole at the top to allow air into the bottle as reagent is drawn out.
Thin .3mm thick rim which seats to the bottle rim and minimizes tube elevation in the reagent.
Tested and verified the tip does not extend down into the fluid on a new bottle of reagent.
Printed in reef safe ABS plastic.
