Product Description

The BRAND Titrette® bottletop burette makes routine titrations faster, easier, and more accurate. The Titrette® avoids the risk of spills from poured transfers to glass or plastic burettes, eliminates meniscus reading errors and offers accuracy that satisfies the tolerances for Class A glass burettes. The instrument is well suited for general chemistry, water treatment applications, food/beverage analysis, industrial titrations, and environmental work in the lab or field.


Class A Precision The Titrette® bottletop burette has an innovative new measuring system which matches the Class A error limits of glass burettes according to DIN EN ISO 385 and volumetric tolerance per ASTM E287. If needed, it can display 3 decimal places for volumes below 20mL.

Smooth Operation The large, easy-to-grip hand wheels provide exceptionally smooth operation. With the optimized gear ratio, you can fill the device quickly and titrate dropwise with great sensitivity.

Compact Design The Titrette® operates in a fixed position on top of titrant bottles. The low-profile design is stable and fits readily under shelves and cabinets. The compact design and the light weight ensure good stability.

Easy Handling The Titrette® switches automatically between filling and titrating modes. The titrating tube adjusts vertically and horizontally to match receiving vessels, and operation is cordless, using economical commercial batteries that are protected from corrosive vapors.

User Serviceable The Titrette® can be quickly and easily disassembled in a matter of minutes - for cleaning, to replace the piston/cylinder, or to replace the batteries. Maintenance is easy and convenient, without the need to send it out for repair.

Simple Maintenance The Titrette® can be disassembled for cleaning, ensuring long, reliable service even with crystallizing titrants. Easy Calibration™ technology simplifies ISO/GLP compliance.

Light Protection To protect light-sensitive media, the installed clear cylinder inspection windows can be easily replaced with the supplied clip-on amber-colored windows.

PC Interface Models available with RS232 interface for direct data transmission to a PC.

Chemical Applicability The Titrette® is suitable for most commonly used titrants up to 1mol/L in concentration, such as potassium permanganate, silver nitrate, EDTA, sodium hydroxide and alcoholic potassium hydroxide.
