Nalge Nunc International Corp Burette Filler Kit

This Nalge Nunc burette filler kit can convert any plastic or glass 25-milliliter or 50-milliliter burette into a self-zeroing, automatic-filling burette. You no longer need to worry about funneling hazards and messy spills. To use this burette filler, set the adjustable fill tube to the zero mark and squeeze the bottle to fill the burette above the zero mark. When released, the excess liquid returns to the bottle, and the titrant falls to the zero mark. If you want to switch to a different-sized burette, you can reverse the adapter. There is an extra closure included for storing titrants.
