The pulse-free, dispensing operation of the Continuous burettes makes titration safer at high-level precision. The Continuous series can be used for titration agents up to a concentration of 1 Mol/l. The patented dual pristons pump provides permanent and pulse-free the liquid requested. Refills are not necessary. The Continuous burette series undercuts the margins of error defined by DIN EN ISO 8655-3 especially in partial volumes. All operation controls and the digital display have an ergonomic and functional design and are arranged clearly.

• Pulse-free dispensing technique for continuous and quick titration
• patented recirculation valve avoids reagent waste
• Clear and precise display of titrated volume
• Battery-operated, easily replaceable micro-batteries (1,5V)
• Dispensing volume per hand wheel revolution: 2.5ml (Continuous E), 5.0ml (Continuous RS)
• Device can be rotated on the bottle 360°
• Telescopic discharge tube extendible from 140 to 220mm
• Telescopic filling tube extendible from 200 to 350mm
• Adapters for drying tube and filter
• Certificate of conformity according to DIN 12600
