DIGIPETTE Electronic Burette With Magnetic Stirrer For Precise Titrations

The dTRITE electronic burette from the DIGIPETTE range is designed for accurate liquid dispensing in titration and analytical procedures.
Its electronic control system reduces repetitive strain during daily operation and ensures more comfortable handling, particularly in analyses requiring gradual and stable reagent addition.
The integration of a magnetic stirrer in the base allows continuous sample homogenisation, resulting in more consistent and controlled titrations.

Precise Dispensing And Adjustable Control

This unit operates within a volume range from 0.01 to 99.99 ml through successive fillings of a piston with a maximum capacity of 10 ml.
It offers a resolution of 10 μl, together with a precision of R = 0.2% and a coefficient of variation (CV) of 0.07%, delivering accuracy comparable to Class A glass burettes.
Dispensing can be performed in continuous mode or dropwise, making it particularly suitable for analytical titrations requiring precise endpoint control.

Integrated Magnetic Stirrer And Remote Operation

The base incorporates a magnetic stirrer with 5 preset speeds, designed to mix the sample during titration without additional equipment.
The system also features 16 programmable speeds for both aspiration and dispensing, allowing the user to adapt performance to the liquid properties and application requirements.
The remote control helps minimise manual interference during operation and improves user comfort, especially when stable handling or a certain working distance is required.

Materials And Chemical Compatibility

All wetted components are manufactured from fluorinated ethylene propylene (FEP) and PTFE, materials selected for their low chemical reactivity and high resistance. The internal fluid path includes borosilicate glass elements, contributing to enhanced chemical stability when handling a wide range of reagents.
The instrument is compatible with a broad range of chemicals up to a maximum concentration of 1 mol/L, provided manufacturer guidelines and usage limitations are respected.
It must not be used with hydrofluoric acid, liquids containing suspended solid particles that may cause clogging, or certain non-polar organic solvents and highly aggressive reagents.

Functional Design For Daily Use

The burette features an LCD display for monitoring dispensed volume and operating status, as well as a return valve, liquid observation window and pre-filling system.
It also includes an extended dispensing tube, allowing safer and more convenient operation at a distance.
The unit is supplied with adapters for various bottle necks and is compatible with GL45 threaded bottles up to 1,000 ml. The bottle is not included.

Power Supply And Operating Conditions

The unit operates with a 4,000 mA/h rechargeable battery, providing up to approximately 5 hours of operation and charging via a standard USB charger.
It is designed for use within a temperature range of 15 to 40 °C, relative humidity of 20 to 90%, vapour pressure below 500 mbar and maximum viscosity of 500 mm²/s.
The instrument complies with DIN EN ISO 8655 and can be calibrated using dedicated external software to ensure metrological reliability where required.

Applications

This digital burette with magnetic stirrer is suitable for titrations, chemical analysis, routine laboratory work and applications requiring accurate, repeatable and user-friendly dispensing. It is particularly useful in fields such as analytical chemistry, water analysis, food industry testing and other laboratory environments where precise dosing control is essential.
