The Compact G10 and G20 titrators combine Swiss precision with an easy-to-use OneClick™ touch interface, providing dependable potentiometric titrations while occupying minimal bench space. They enhance quality control and research and development processes, reduce training time to mere minutes, and are compatible with plug-and-play sensors, burettes, and optional LabX™ software, resulting in substantial savings in bench space, operator time, and maintenance expenses.
- Reliable accuracy: Sealed burettes and validated electrodes provide repeatability results with an accuracy of ±0.2 %.
- One Click guidance: A touchscreen featuring 12 shortcuts significantly reduces setup errors.
- Scalable methods: G10 provides five different routines; G20 enables 100 dosing methods.
- Plug-&-play start: RFID burettes and sensors, along with 20 pre-installed methods, enable users to power on and begin titrating in just a few minutes.
- Compliance-ready: LabX incorporates audit trails and electronic signatures and facilitates compliance with 21 CFR Part 11 and Annex 11.
Compact Productivity

- High accuracy: Swiss-engineered burettes and electrodes maintain a dosing precision of ±0.2 % consistently, run after run.
- Space saver: All controls, dual stirrers, and a 5.7-inch touchscreen are designed to fit within a 20 cm footprint, making them ideal for crowded workbenches.
- Low-cost lifetime: The sealed drive and maintenance-free mechanics ensure that the requirements for annual servicing and expenditures on spare parts remain minimal.
Scalable Method Capacity

- Right-sized memory: G10 includes five fundamental methods; G20 extends to over 100, in addition to a secondary dosing mechanism and 12 shortcuts.
- 120-sample queues: Series templates facilitate the automation of extensive batches, whereas optional Rondolino processes nine samples without supervision.
- Future-proof upgrades: A barcode reader, solvent manager, or LabX can be integrated at any time without needing a new instrument.
OneClick Guided Operation

Automatic Titrator, Compact G-Series
The Compact G10S and G20S titrators substitute manual burettes with Swiss-engineered precision, providing reliable and traceable outcomes irrespective of the operator's expertise. OneClick shortcuts enable immediate initiation of common acid/base, redox, or chloride content measurements, while automatic calculations and statistics complete the task. Optimize bench space, reduce training time to mere minutes, and allow staff to focus on more valuable tasks.
Compact G10S
