Description
Digital burette / bottle top burette Titrex The digital burette TITREX is ideal for fast and sensitive titration in 10 μl steps. A titration volume of up to 99.99 ml is covered with an instrument. The new TITREX makes titration particularly economical: Not a drop of reagent is used unnecessarily! From deaeration as preparation for an exact titration to the end of the titration - the reagent that is not required for titration flows back into the bottle! The accuracy and precision of the device are excellent, our error limits are better than the requirements of ISO 8655. In addition, up to 1000 measured values can be saved, which can then be transferred to the PC and read with the supplied software. Your benefits at a glance: - High quality precision instrument, made in Germany - Highest accuracy and precision, our error limits are better than the requirements of ISO 8655-3 - Resistant to most acids and alkalis - 0% loss of reagent due to reverse dosing - 360 degrees rotatable valve head for your safety - Dual function: dosing and titration - One instrument for every volume range up to 50 ml as a dispenser, up to 99.99 ml as a burette - Quick and precise volume adjustment - Vertical valves - no sedimentation, no contamination - 100% drip-free thanks to unique, 180 degrees rotatable cannula - No transmission errors due to the automatic storage of values and the possibility of transfer to a PC via an RS232 interface (USB adapter optional) - Calibration: standard with water at 20 degrees C - It is possible to reserve the next calibration date - Recalibration for media of different density possible, for example to determine the acidity of milk - Easy to dismantle and clean, valve head autoclavable at 121 degrees C - NiMH 1.2V 2100mAh battery - Automatic shutdown after 3 minutes - Individual certificate, CE marking and serial number - DE-M marking according to the German MessEV Titrex, suction pipe, ejection cannula, operating instructions, individual certificate, serial number, charger with EU and US adapter, software Titrexsoft, RS232 connection cable, thread adapter A25, A28, GL32 / 45, S40
Feature
Fast and precise volume setting: The volume to be dispensed or titrated is set using the rotary knobs. Choose between dosing and titration mode by pressing the "DOS" or "TIT" button. Depending on the mode, the digital display shows the titrated or dosed volume. Perfect ventilation without loss of reagent: turn the cannula 90 degrees. By turning the handwheels you remove the air without losing any reagent. The liquid flows back into the container! After turning the handwheels 2-3 times in the closed system, your digital burette is free of air and ready for use. This special feature is also useful for pumping remaining amounts of reagents back into the bottle. Practical: Works even if you made a mistake in the volume selection. 360 degrees rotatable valve head for additional safety: No matter how firmly you screw the burette onto the reagent bottle, you can turn the cannula with one hand so that its label is always visible when working with the TITREX. The use of adapters does not limit this function. 100% non-drip system for your safety: By rotating the cannula by 180 degrees you ensure that the liquid flows back into the bottle. Your TITREX is safely set in this position: no dripping is possible. Even an inadvertent actuation of the piston does not lead to uncontrolled ejection of liquid. Easy recalibration of the piston for a long service life: If you use TITREX as a measuring device according to ISO 9001 and GLP, accuracy and reproducibility must be checked and documented regularly. The calibration function is activated by pressing the CAL key. After measuring the nominal volume, the values can be adjusted using the +/- keys. TITREX can also be set for solutions of different densities and viscosities. TITREX can also be recalibrated using the supplied TITREXSOFT software. TITREXSOFT (included in the scope of delivery): By accessing the memory of the TITREX, all values can be transferred to a PC - no more transmission errors! The completely newly developed software helps to process the stored data. The values can either be transferred in real time during the titration or later. Using the logging function, the data can be printed or saved together with the automatically created graph. All wetted parts are made of chemically resistant materials: platinum spring, ceramic valve balls, PTFE piston, valve and cylinder made of borosilicate glass 3.3Ulasan Produk
