SKZ is honored to be a trusted supplier of analytical instruments to The Coca‑Cola Company – a Fortune 500 leader where moisture content is a critical quality parameter across the supply chain. From the water activity of powdered ingredients and the residual moisture in plastic preforms to the trace water in organic solvents used in flavour extractions, precise water determination ensures product stability, shelf life, and processing efficiency. That is why Coca‑Cola’s global quality laboratories have adopted the SKZ KFT‑40VC Karl Fischer titrator. This versatile instrument combines volumetric and coulometric titration modes in one compact unit, delivering accurate moisture results from 10 µg to 250 mg, backed by SKZ’s commitment to precision, reliability, and responsive service. Our latest shipments reached multiple Coca‑Cola sites in mid‑2026, and order volumes continue to grow as more facilities recognise the value of flexible, high‑performance moisture analysis.
The KFT‑40VC stands out with its dual‑mode capability: volumetric titration for higher moisture content (100 µg – 250 mg) and coulometric titration for trace moisture (10 µg – 20 mg). Operators can switch between modes with a single key, eliminating the need for separate instruments. This flexibility is invaluable for Coca‑Cola’s diverse testing needs – from checking the moisture of incoming sugar (volumetric) to measuring residual water in organic solvents used for caffeine extraction (coulometric). One instrument, two methods – maximising laboratory efficiency and minimising capital expenditure.
The volumetric mode covers 100 µg to 250 mg of water, ideal for solid powders, syrups, and pastes. The coulometric mode covers 10 µg to 20 mg, perfect for low‑moisture samples like oils, fats, and non‑aqueous solvents. This broad range ensures that the KFT‑40VC handles virtually any sample matrix encountered in Coca‑Cola’s operations, providing reliable results whether the moisture level is near‑zero or well into the percentage range.
Volumetric repeatability ≤0.5% ensures that replicate measurements of the same sample yield tight, reproducible results – essential for validating production batches and meeting internal specifications.
Coulometric RSD at 100 µg ≤3% and accuracy of ±(5% reading + 3) µg guarantee that even ultra‑trace moisture levels are measured with confidence. For Coca‑Cola’s quality teams, this precision translates into fewer re‑tests, reduced waste, and faster product release.
The KFT‑40VC is fully GLP‑compliant, storing up to 200 data sets complete with time‑stamps, method parameters, and results. This comprehensive record‑keeping supports full traceability – critical for audits, regulatory submissions, and supplier quality reviews. Coca‑Cola’s laboratories appreciate the ability to retrieve historical data instantly, simplifying trend analysis and batch‑to‑batch comparisons.
Equipped with PC and printer communication ports, the KFT‑40VC allows seamless data export to laboratory information management systems (LIMS) or direct report printing. This feature eliminates manual transcription errors and accelerates documentation, freeing analysts to focus on interpretation rather than paperwork – a significant advantage in Coca‑Cola’s high‑throughput quality environments.
The instrument features a clear LCD screen that displays titration status, curves, and parameters in real time. Operators can monitor the process at a glance, making it easy to identify endpoints and troubleshoot. Combined with rugged construction and intuitive controls, the KFT‑40VC is built for daily use in busy industrial laboratories, requiring minimal training and maintenance.
Coca‑Cola’s continued trust in SKZ is a testament to our dedication to quality and innovation. Our latest KFT‑40VC deliveries have been deployed across multiple global sites, and demand is rising as more laboratories adopt our versatile titration solution. At SKZ, our promise remains unchanged: laboratory‑grade precision, rock‑solid reliability, and service that goes beyond the sale. Together with The Coca‑Cola Company, we ensure that every raw material, every intermediate, and every final product meets the strictest moisture specifications – safeguarding the taste
and consistency that consumers trust worldwide.
