Calibrex™ organo525 / solutae530 Bottle Top Dispensers
This new generation of Socorex® Bottle Top Dispensers is 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.
Product Advantages
■ Selection between organo and solutae models for
best chemical resistance
■ Permanent fluid path visibility
■ Integrated calibration system
■ Choice of adjustment button with each unit
■ Long lasting performance stability
■ Autoclavable at 121°C / 250°F fully assembled
■ Two year warranty
Choice of Setting Buttons
Spring loaded sliding cursor  softly moves up and down scale and
precisely stops at desired graduation. Alternative classical screw button 
supplied with each dispenser for easy exchange.
Color Coding
Yellow for organomodel best suited for organics, non-crystallizing acid and
base solutions. Red for s olutaemodel enabling trouble-free distribution of
salt solutions, weak and strong acids, as well as bases.
Material Selection
Parts in contact with liquid flow are chemically inert, providing for
stability and long instrument life.

*Performance values obtained by a smooth and steady pace movement, with bidest. water at constant temperature (± 0.5°C) comprised between 20°C and 25°C, according to EN ISO 8655. Omission to
untighten connecting body ring before autoclaving, and/or over-tightening ring when dispensing, may reduce performance.
