Makes any plastic or glass 25- or 50-mL buret self-zeroing, economically and easily. More economical than costly glass self-zeroing burets. Kit includes 1000mL low-density polyethylene bottle, four feet of clear Nalgene™ PVC plastic tubing and polypropylene fill-tube and adapter.
No more funneling; hazardous, wasteful spills are eliminated. Can be used with almost all aqueous titrants. Set adjustable fill-tube to zero mark on buret. Squeeze bottle to fill buret* just above zero mark. Release and excess liquid returns to bottle and titrant falls to the zero mark. To switch to a different size buret, simply reverse the adapter. Extra closure without tubing hole is included for storing titrants or carrying to the field.
*Buret not included in kit.
