Wheaton Calibrex organo/solutae Bottle Top Dispensers are a new generation of Socorex Bottle Top Dispensers, and are intended for the safe and reproducible liquid distribution of volumes up to 25, 50 and 100mL. The Calibrex organo 525 includes a ground glass plunger, best suited for organics, non-crystallizing acid and base solutions. The Calibrex solutae 530 has a PFA coated plunger preventing the plunger and barrel from seizing together. This enables trouble free distribution of salt solutions, weak and strong acids, as well as bases.
