A sugar cargo leaves Santos with a contract color limit, and the buyer's lab reports a different number. A biodiesel plant releases a batch, and the distributor questions its shade. In Brazil, color disputes often start with an outdated method, not a bad product.
A Color Spectrophotometer in Brazil replaces visual comparators and single-scale meters with objective transmittance data. Qualitest supplies liquid and solid color instruments that calculate ICUMSA, Gardner, EBC, and platinum-cobalt values from one spectral reading, so every party works from the same number.
Why Liquid Color Data Carries Weight in Brazil
Brazil's economy runs on liquids and crystals that trade on color. Each sector below ships high volumes, which turns a small measurement error into a large commercial problem.
Sugar and Ethanol
Brazilian sugar exports reached 33.77 million tonnes in 2025, the second-largest volume on record, according to Secex data compiled by Datagro. Mills in São Paulo and Minas Gerais grade white and raw sugar by ICUMSA color, and that value often sets the price tier.
At the same time, mills split cane between sugar and ethanol every season. Therefore, the same lab frequently checks syrup, crystal sugar, and hydrated ethanol on one shift.
Biodiesel and Vegetable Oils
The CNPE raised the national biodiesel blend to B15 on August 1, 2025, under the Fuel of the Future law. In addition, the law schedules yearly increases toward B20 by 2030, and soybean oil supplies roughly three quarters of biodiesel feedstock.
Consequently, crushers and refiners in Mato Grosso, Paraná, and Rio Grande do Sul need reliable Gardner and ASTM color checks on crude and refined oil.
Brewing
Brazil ranks as the world's third-largest beer producer, behind China and the United States. The MAPA Beer Yearbook counted 1,847 registered breweries in 2023, and craft producers need the same EBC color control that large brewers already use.
Matching Brazilian Products to the Right Color Scale
Each industry speaks its own color language. The table below shows how the scales built into the Qualitest liquid instruments map to Brazilian production lines.
| Brazilian Product | Color Scale | Typical QC Point |
|---|
| Crystal and raw sugar | ICUMSA color | Export grading, mill release |
| Soybean oil, biodiesel | Gardner index, ASTM Color | Refining, blend release |
| Beer and malt extracts | EBC color | Brewhouse, packaging line |
| Ethanol, solvents, resins | APHA / Pt-Co, Saybolt | Purity and contamination checks |
| Pharmaceutical solutions | EP and USP color | Batch release under ANVISA oversight |
Instead of buying a separate comparator for each scale, a lab runs one sample and reads every relevant index. As a result, one color spectrophotometer in Brazil can support a mill, a crusher, or a contract lab that serves several clients.
Choosing a Color Spectrophotometer in Brazil: LC1 or LC2
Qualitest offers two models in its liquid color spectrophotometry line. Both use d/0 geometry, a 360 to 780 nm range, and a 7-inch touchscreen. The key difference is temperature control.
The QualiSpec Quali-LC1 suits samples that stay clear at room temperature, such as sugar solutions, ethanol, and beer. It delivers repeatability of ΔEab ≤ 0.015 and inter-instrument agreement below ΔEab 0.25.
The QualiSpec Quali-LC2 adds heating from ambient to 90°C. That matters for fats, waxes, and oils that cloud or solidify in an air-conditioned lab. Use these points to decide:
- Sample state: choose the LC2 if samples need melting or warming before reading.
- Network size: the LC2's tighter agreement (below ΔE*ab 0.2) helps groups that compare results between several plants.
- Path length: both accept 10 mm and 50 mm cuvettes as standard, with 33 mm and 100 mm options for very pale or very dark samples.
- Data integrity: both models include an audit trail aligned with FDA requirements, which supports regulated pharmaceutical and food labs.
Solid-Sample Color Control Beyond the Cuvette
Many Brazilian plants also need to measure surfaces, not just liquids. For example, sugar and beverage producers check printed labels, PET preforms, and caps against brand masters.
For those tasks, Qualitest supplies portable color spectrophotometers for packaging lines and warehouses. Meanwhile, the Color2View benchtop series handles plastics, coatings, and textile swatches in the central lab. Combining both formats lets one QC team cover the bottle and the liquid inside it.
Standards Coverage and Lab Requirements
Brazilian buyers often follow international methods alongside local rules. According to the Qualitest product pages, the Quali-LC1 and Quali-LC2 measurement condition complies with these standards:
- CIE No. 15, ISO 7724/1, ASTM E1164, and DIN 5033 Teil 7 for colorimetric measurement
- ASTM D1500 and ASTM D156 for ASTM Color and Saybolt Color of petroleum products
- ASTM D1209 and ASTM D5386 for platinum-cobalt color of clear liquids
- ASTM D6166 for instrumental Gardner color of resins and oils
Laboratories seeking INMETRO accreditation under ISO/IEC 17025 also need documented calibration and traceable results. The intelligent zero calibration and 100,000-record storage on both models help labs build that evidence. Furthermore, ANP fuel-quality oversight and ANVISA rules shape how plants document each batch, so stored data saves time during audits.
Set Up Your Color Methods Before the Next Harvest
Brazil's cane crush, soybean harvest, and peak beer season each compress testing into a few busy months. Therefore, labs that configure their color methods early avoid bottlenecks when sample volume peaks.
Qualitest can help you select cuvette sizes, assign color scales to each product, and decide whether your samples need the heated LC2. We also support multi-site groups that want matching instruments across plants.
Contact Qualitest with your product list and target color scales, and our team will recommend a configuration for your laboratory in Brazil.
