ceramus®
A dispenser with a reagent recirculation system for manual dispensing directly from the reagent bottle. Available in six different volumes.
Uncompromising reliability - years of experience gained by Hirschmann in liquid handling are reflected in the perfection embodied in ceramus® and absolute attention to detail. The graduation gauge and digital volume configuration engagement guarantee consistent precision and volume dispensing and ensure reproducible results – absolutely independent of the user. The dispensing piston made of high-purity aluminium 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 aluminium oxide ceramic, the valve seats and balls are ceramic and valve springs are made of platinum / iridium.
