1 Titrex ACT titrators have been designed to simply and precisely satisfy and perform the widest range of potentiometric titrations: acid-base, redox, argentometric, complexometric titrations Compact and modular: Titrex ACT is a compact as well as modular instrument. It can be configured at will, therefore it is fitted to satisfy the ever-changing laboratory requirements. The burettes for titrant solutions and the peristaltic pumps for the auxiliary reactants can be integrated to the system at any time Upgrade: the software upgrade is simply performed by connecting the Titrex ACT to a PC Easy to use: the wide graphic display contains all the messages and the icons that make Titrex ACT extremely easy to use. The titrator guides the user in each programming phase, analysis and data interpretation On-line graphics: during the titration process the graphic trend is displayed in real time, so that the operator is immediately informed about the analysis trend GLP: each analytical report obtained with the Titrex is complete and reports: company/institution and operator name, analysis date and time, sample alphanumeric code, titrant consumption, volume/weight, result reported in the desired unit (e.g. %, g/l...) etc.

2 Titrex ACT Standard titration programs: (it is possible to save in memory up to 30 programs): FINAL POINT: titrations with pre-defined ph/mv value EQUIVALENCE: titrations with automatic localization of the equivalent point/s, and pre-defined or incremental additions during the titration (up to 4 equivalent points) Service programs: DOSAGE: dispensing of pre-defined fixed volumes PRIMING AND CLEANING: reactants loading and cleaning at the end of the work Calibration, measurements in ph/mv Programs specific to oenology: PH AND TOTAL ACIDITY: it is performed with a ph electrode (final point titration to ph 7.00) without sample pre-treatment FREE AND TOTAL SO2: it is performed with double platinum electrode, without sample pre-treatment. Once the sample aliquots have been proportioned in the respective titration vessels, the analysis includes the automatic additions of the auxiliary reactants (H2SO4 and NaOH) by means of peristaltic pumps, with automatic control of the waiting time (alkaline reaction for total SO2). Free, total and combined SO2 analysis can be performed on the same sample (double Ripper) as well REDUCING SUGARS: the analysis is performed by means of redox titration with a platinum electrode on decolorized and diluted within 25g/l sample. Once the sample aliquots (5ml) have been manually proportioned in the respective titration vessels the analysis can be performed by previous oxidation of the samples on heating plate. With the help of the heated sampler the analysis of the reduction sugars, including the oxidation, is fully automatic, with no intervention of the operator oenological division Hardware technical features: - wide, clear and evident graphic display - 2 outputs for combined electrodes: ph: (0.01pH) mv: ñ (0.1mV) - 1 output for reference electrode - 1 output for temperature sensor: C - parallel connection to printer and RS232 C serial connections to external PC and scale, RS 485 serial connection to burettes, optional peristaltic pumps (max. 5), 16-position standard or thermostatable sampling plate - plastic compact structure, dimensions (WxLxH) mm 610 x 310 x 360 (electrodes stand excluded) Precision burettes for titrant delivery (max. 4) equipped with: - extremely high resolution stepper motor (48,000 steps) - 10ml standard syringe made of graduated clear glass with interchangeable PtFE-tip - four-way valve for titrant inlet, washing reactant inlet, titrant delivery and connection to the syringe.
