Automatic Refractometer LAR-A14

Labtron’s automatic refractometer LAF-A14 uses a high-resolution linear CCD detector that captures the critical-angle intensity gradient at the prism-sample interface. This precision detection ensures accurate refractive index (nD) or concentration (e.g., Brix) measurements—even with transparent, turbid, viscous, or dark samples—minimizing operator dependency. The captured optical signal is processed digitally, increasing repeatability and consistency across repeated measurements. Equipped with long-life LED light sources and quality sapphire prisms, the system reduces drift and degradation over time. This setup enables fast, reliable results regardless of sample clarity or viscosity. It’s ideal for industries such as sugar, pharmaceuticals, beverages, petroleum, and chemicals, where precision and throughput matter.

Labtron’s automatic refractometers LAR-A14 integrate Peltier-based temperature control and onboard sensors to maintain stable prism and sample temperatures. This precise control is crucial because refractive index varies with temperature—often by around so thermal fluctuations can introduce significant error. With rapid temperature stabilization and programmable temperature compensation algorithms, instruments deliver consistent readings despite ambient changes. The result is high accuracy and reduced recalibration frequency. Such robust thermal management makes automatic refractometers suitable for demanding quality-control environments in food, pharma, and petrochemical industries

Labtron’s automatic refractometers LAR-A14 are equipped with comprehensive software-driven data handling, including configurable data output formats (e.g., CSV, PDF, Excel). Measurements are automatically logged into an internal database with user metadata and timestamps, enabling audit readiness. Many units support automatic export of results to USB drives, printers, network folders, or even directly into LIMS via Ethernet or RS 232 connections. Built-in statistical functions and method templates ensure consistent handling of routine analyses. Instruments also often support user rights and audit trail features compliant with regulations like FDA 21 CFR Part 11. This capability streamlines workflows and minimizes transcription errors in regulated lab or production settings
