Labor Accura – Automated Flux Dispensing System

Eliminate weighing variability and streamline geochemical workflows

Labor Accura brings automation, precision, and reproducibility to a critical step in XRF sample preparation. By eliminating manual weighing and ensuring consistent flux/sample ratios, it enables geoscience laboratories to achieve higher data quality, improved efficiency, and scalable throughput.

Key Features
- Automated sample-to-flux ratio control – Eliminates manual calculation and reduces operator error
- High precision dosing (up to 0.0001 g) – Ensures reproducible XRF fusion bead preparation
- Improved laboratory throughput – Significantly reduces preparation time per sample
- Contamination-free operation – Closed dosing system prevents exposure to air, moisture, and handling
- Operator-independent workflow – Standardises preparation across shifts and users
- Seamless integration – Communicates with analytical balances and XRF software platforms
- Compact, benchtop design – Ideal for high-throughput labs with limited space
- Enhanced data traceability – Supports digital workflows and LIMS integration

The Labor Accura from Oregon Labware is an automated weighing and dosing system purpose-built for XRF sample preparation workflows. Designed for geoscience laboratories, it precisely measures both mineral samples and fusion flux, automatically calculating and dispensing the correct ratio for consistent bead preparation.
By removing manual weighing steps, Labor Accura delivers highly reproducible sample-to-flux ratios while significantly improving laboratory throughput. Its ability to interface with analytical balances and XRF software environments makes it a seamless addition to modern geochemical and mineral processing labs.

The Benefits of Automated Flux Dispensing

Labor Accura automates one of the most error-prone steps in XRF sample preparation—accurate weighing and dosing of flux and sample. It operates in two primary modes:

Precision flux dosing: delivers highly accurate, repeatable flux masses
Automatic ratio calculation: determines and dispenses the correct flux based on measured sample weight

This ensures consistent dilution ratios, improved fusion quality, and reliable downstream analytical results.

Automated Flux Dispensing in Geoscience

In geoscience laboratories, particularly those performing X-ray fluorescence (XRF) analysis, consistency in sample preparation directly impacts analytical accuracy. Variations in flux/sample ratios can introduce significant errors in elemental quantification.
Labor Accura addresses this by standardising the weighing process, ensuring each fusion bead is prepared with identical proportions. This is especially valuable in:

Mining and mineral exploration labs
Geochemical assay laboratories
Environmental and soil analysis facilities
Academic research institutions working with geological materials

The result is improved analytical confidence, reduced rework, and faster turnaround times for high-volume sample batches.

Applications

Labor Accura is ideally suited for:

Geochemists and XRF analysts requiring high reproducibility
Mining and exploration laboratories handling large sample volumes
Commercial assay labs seeking automation and standardisation
Research institutions aiming to minimise variability in analytical workflows
