Oils 7400 Homogenizing Autosampler - Dual-Matrix Sample Automation for Oils & Coolants Testing As oils testing laboratories face increasing complexity and more diverse sample types, the Oils 7400 Homogenizing Autosampler delivers accurate, reliable automation for ICP analysis. Designed for dual-matrix workflows, the Oils 7400 allows labs to introduce both oil and coolant samples from a single system with fast switching and minimal downtime. Featuring a dual-port rinse station powered by two peristaltic pumps, improved mixing capability, and advanced drip capture, the Oils 7400 supports robust, contamination-resistant sample handling without compromising throughput or data quality. Key Benefits *Mix samples immediately prior to analysis for accurate results *Dual-matrix design enables fast switching between oils and coolants *Fast, smooth XYZ movement for high throughput *Accurate positioning to ± 0.4 mm *No probe or stirrer alignment drift *Integrated drip capture minimizes cross contamination *Reliable analysis for viscous and particulate samples Why Sample Mixing Matters: Used oil samples often contain particulate matter that settles at the bottom of the sample tube prior to analysis, which can cause non-representative results. The Oils 7400 is specifically designed to eliminate this issue.A stirring paddle mounted next to the sample probe mixes each sample immediately before measurement. Both the probe and stirrer are cleaned at the rinse station to reduce carryover. Mixing parameters are configurable through the dashboard software to handle viscous oil samples. Accurate & Fast Operation *Each sample is automatically homogenized prior to analysis *While one sample is being drawn, the next sample is stirred for maximum efficiency *Faster and smoother XYZ movement saves up to 2 seconds per sample compared to previous models *Analyze up to 2 samples per minute using ASXPRESS PLUS rapid sample introduction *Supports ASTM 5185 and ASTM 6130 testing standards Maintain Sample Integrity *Integrated drip cup travels with the sample probe and stirring paddle to capture droplets and prevent cross contamination *Dual-port rinse station minimizes analyte carryover *Robust sample handling for challenging matrices Fast Switching Between Oils & Coolants The Oils 7400 supports two discrete liquid flow paths and a dual port rinse station, allowing rapid switching between oils and coolants in as little as 5 minutes. Oils rinse: kerosene or white spirit Coolants rinse: water or nitric acid By swapping the sample probe, stirring paddle, and ICP glassware, labs can switch between workflows quickly and efficiently. Filtered Probe for Longevity :The included stainless steel filtered probe helps filter out large particles, protecting downstream components and extending system lifetime. The probe is durable and easy to clean. Ideal Applications: *Used oil analysis *Lubricant testing *Coolants testing *ASTM 5185 and ASTM 6130 compliance *Industrial and automotive testing labs *ICP-MS and ICP-OES sample automation
