Ceramic dispensing piston: ceramus ® has a resistant special piston made of high-purity AI 2 O 3 . Advantages of the ceramic piston: • no abrasion • no swelling • no thermal problems High resistance to chemicals: • top-grade materials guarantee very high resistance to chemicals Best handling: • user-friendly recirculation system for fast venting without loss of reagent - good ecology and economy • latching setting ring for fast and extremely precise settings • ergonomic handle and excellent sliding properties of the dispensing piston facilitate operation for series dispensings Modern, well arranged design Precision and accuracy: • no re-calibration necessary thanks to a combination of self-latching settings and permanently calibrated volume steps • individual quality certificate acc. to DIN ISO 9000 ff., suitable for use as test equipment • with declaration of conformity acc. to DIN 12600 Exemplary safety and choice of materials: • protective casing helps to prevent breakage of glass cylinders and dispensing bottles • screw-coupled suction tube prevents the formation of air bubbles during aspiration • the device is freely rotatable so the label on the supply bottle is always in view • guided discharge cannula prevents “snip effect” with the dispensing media User-friendliness • Suction, ejection, and return valve are made of highly pure AI2O3 ceramic material (99.7%), are inert to the greatest possible extent as well as non-wearing. Easy to replace (mounting wrench enclosed • Sterilizable with steam, also when fully assembled Additional merits: • Discharge unit available with Luer-Lock connection • Spiral discharge tube available for series dispensings • Venting of bottle via the Luer-Lock connection • Screw-coupled suction tube • Environment-friendly packaging, fully recycleable • 12-month manufacturer‘s warranty Items supplied: • ceramus ® complete with thread A45, 3 thread adapters (A 32, A 38, and S 40), 1 suction hose with union nut, 1 ejector unit, 1 valve mounting wrench, single calibration certifi- cate. Special version for problematic media: • ceramus ® HF is a special version for dispensing hydrofluoric acid and other aggressive media • Innovative dispensing system made of top-grade materials 1 ceramus ® adjustable volume Volume ml Sub-division ml R % CV % Order No. 0.2 – 1.0 0.05 0.6 0.2 14 37 93120 0.4 – 2.0 0.05 0.6 0.2 14 37 93220 1.0 – 5.0 0.10 0.6 0.2 14 37 93320 2.0 – 10.0 0.25 0.6 0.2 14 37 93420 5.0 – 30.0 0.50 0.6 0.2 14 37 93520 10.0 – 60.0 1.00 0.6 0.2 14 37 93620 2 ceramus ® fixed volume Volume ml Sub-division ml R % CV % Order No. 1 - 0.6 0.2 14 37 93121 2 - 0.6 0.2 14 37 93221 5 - 0.6 0.2 14 37 93321 10 - 0.6 0.2 14 37 93421 25 - 0.6 0.2 14 37 93521 50 - 0.6 0.2 14 37 93621 Volumetry Dosing Devices
