SKZ is honored to be a trusted partner of The Coca‑Cola Company – a Fortune 500 leader where moisture content is a silent but critical factor in product integrity. From the moisture in powdered flavourings and sweeteners to the trace water in organic solvents used for caffeine extraction and the residual humidity in PET preforms, accurate water determination directly affects flavour stability, shelf life, and production efficiency. That is why Coca‑Cola’s global quality laboratories have standardised on the SKZ KFT‑40VC Karl Fischer titrator. This versatile instrument combines volumetric and coulometric titration in a single compact unit, delivering precise results from 10 µg to 250 mg of water. Every unit we supply is backed by our dedicated technical support, routine maintenance guidance, and a commitment that turns every purchase into a lasting partnership. Our latest shipment reached multiple Coca‑Cola sites in mid‑2026, and order volumes are steadily climbing as more facilities adopt this dual‑mode solution – ensuring that every ingredient and package meets the company’s rigorous moisture specifications.
The KFT‑40VC stands out with its one‑key switching between volumetric and coulometric modes. This unique feature eliminates the need for two separate instruments, saving bench space and capital investment. The volumetric mode handles higher moisture levels (100 µg – 250 mg) – ideal for syrups, pastes, and solid powders. The coulometric mode excels at trace moisture (10 µg – 20 mg) – perfect for oils, fats, and non‑aqueous solvents. For Coca‑Cola’s diverse testing needs, this flexibility means a single titrator covers everything from incoming sugar to refined flavour oils.
With volumetric range 100 µg – 250 mg and coulometric range 10 µg – 20 mg, the KFT‑40VC accommodates virtually all sample matrices encountered in beverage production. Whether it is measuring the 2‑3% moisture in corn syrup or the <0.1% residual water in food‑grade lubricants, the instrument delivers reliable readings without range switching hassles. This broad capability reduces the number of instruments required in the lab, streamlining procurement and training.
Precision is non‑negotiable for Coca‑Cola’s quality teams. The KFT‑40VC delivers volumetric repeatability ≤0.5%, ensuring that replicate measurements of the same batch are tightly clustered – essential for statistical process control and batch release. For trace analysis, the coulometric mode offers RSD ≤3% at 100 µg and accuracy of ±(5% reading + 3) µg, giving analysts confidence even at near‑zero moisture levels. This high reproducibility minimises re‑testing, saves time, and reduces reagent consumption.
The KFT‑40VC is fully GLP‑compliant, storing up to 200 complete data sets including method parameters, raw titration curves, results, and time‑stamps. This robust data management supports full traceability – critical for internal audits, supplier qualification, and regulatory inspections (e.g., FDA, EU). Coca‑Cola’s chemists can easily retrieve historical records for trend analysis or investigate out‑of‑spec results, ensuring continuous improvement in moisture control.
Equipped with PC and printer communication ports, the KFT‑40VC enables direct data export to laboratory information management systems (LIMS) or instant report printing. This connectivity eliminates manual transcription errors and accelerates documentation, allowing quality personnel to focus on interpretation rather than administrative tasks – a significant productivity boost in high‑volume testing environments.
The instrument features a clear LCD screen that displays titration progress, electrode potential, temperature, and calculated results in real time. Operators can visually track the endpoint and identify any anomalies immediately. The intuitive interface reduces training time and ensures that even rotating staff can operate the titrator with confidence, maintaining consistent data quality across shifts.
Coca‑Cola’s continued trust in SKZ reflects our relentless dedication to precision and service. Our latest KFT‑40VC shipments have been deployed across multiple global laboratories, and demand is rising as more sites recognise the value of a single, dual‑mode titrator. At SKZ, our promise remains unchanged: laboratory‑grade accuracy, robust reliability, and service that supports our customers at every step. Together with The Coca‑Cola Company, we ensure that every raw material and final product meets the strictest moisture standards – safeguarding the consistent taste, texture, and safety that billions of consumers enjoy daily.
