About Bottle Top Liquid Dispenser
Bottle Top Liquid Dispenser, Recirculation System, Variable Volume
CERAMUS
From hirschmann laborgerate GMBH & co. Germany
A dispenser with a reagent recirculation system for manual dispensing directly from the reagent bottle. Available in six different volumes. The dispensing piston made of high-purity aluminum oxide ceramic and the DURAN glass cylinder guarantee a maximum level of chemical and thermal resistance. The high-quality materials in all parts conveying medium enable use within a temperature range from 4 C to 50 C. The complete unit can be steam sterilised at 121 C without dismantling.
A special HF version designed for dispensing very aggressive media is also available. The piston and cylinder are made of high-purity aluminum oxide ceramic, the valve seats and balls are ceramic and valve springs are made of platinum / iridium.
