For quickly and reliably titration with highest precision, even in close quarters, with no mains supply needed - in the lab, in production, or in the field. The Titrette® bottle-top burette has an innovative new measuring system which matches the Class A accuracy of glass burettes and, if needed, can offer the precision of 3 decimal places below 20 ml. This is an important feature for users who need to work within the Class A error limits as with glass burettes according to DIN EN ISO 385 (e.g. pharmaceutical work). The titrating tube can be adjusted horizontally and vertically. This provides flexibility when positioning the instrument, e.g., when using a magnetic stirrer or different bottle sizes.High accuracySmooth-running operation for sensitive, drop-wise titration and fast filling of the deviceCompact design, light and stableEasy handling, no switching between fill and titrateSimple maintenance, cleaning and parts replacement right in the labScope of supply: Titrette® bottle-top burette, DE-M marking, performance certificate, telescoping filling tube (170 to 330 mm), recirculation tube, 2 x 1.5V batteries (AAA/UM4/LR03), PP bottle adapters (GL32, S40, NS29/32), 2 coloured light shield inspection windows
Burette bellows for automatic burettes is made out of best quality natural rubber.

A titration unit with a reagent recirculation system for manual titration directly from the reagent bottle. Power supplied by a solar cell. Available in three volumes (10 ml, 20 ml and 50 ml). The world's first digital burette with integrated solar cell. The power supply for the electronics and display is derived exclusively from an integrated solar cell. Easily replaceable valves. The vivid digital display prevents meniscus reading errors and is always clearly legible, regardless of the viewing angle. The handwheels with soft touch surface are ergonomically optimised for particularly precise control.Power supplied by a solar cellFree rotationMedia recirculating system for simple and rapid venting without reagent lossHandwheels with soft touch surfaceClearly legible display, regardless of the viewing angleA light protection window for the valve block is also included in the scope of deliveryIndividual calibration of user-specified adaptations with "Quick-Cal"Discharge valves and valve seats consisting of high-purity aluminium oxide ceramicSerial bidirectional interface (RS 232 and USB)Supplied with: solarus® with A 45 mm thread, 3 thread adapters ( A 32, A 38 and S 40), discharge tube, 1 suction tube with retainer screw, 1 spanner for valve, brown light protection window, with individual serial number and single calibration report.
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 titrationpatented recirculation valve avoids reagent wasteClear and precise display of titrated volumeBattery-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 220mmTelescopic filling tube extendible from 200 to 350mmAdapters for drying tube and filterCertificate of conformity according to DIN 12600Supplied with: Burette continuous, 3 PP adapter (GL 32, GL 38, S 40), 1 teleskopic suction tube, 1 teleskopic discharge tube, 2 micro batteries 1.5 V (LR 03/AAA), manual, quality certificate.
