The new Oils 7400 Homogenizing Autosampler has been designed to meet the rigorous demands of oils analysis in the rapidly evolving oils testing industry. This automation marries together sample mixing capability with speed and eliminates cross contamination with improved design drip capture. 

​The Oils 7400 Homogenizing Autosampler offers oils and coolants sample introduction to ICP instrumentation from the same automation.​ It boasts a sliding dual segregated rinse station fed by two separate peristaltic pumps to change between oils and coolants testing on demand. 

Combined speed, mixing capability and improved sample drip capture, deliver robust analysis without compromise.​

Sample Homogenization

Used oil samples that require analysis for wear metal element s t ypically contain particulate material that can settle in a sample tube prior to analysis; this can lead to generation of non‑representative data. The Oils 7400 automation has been designed and developed to resolve this problem on a sample by sample basis in each analytical batch.

Prior to analytical measurement, each sample is automatically homogenized by the autosampler. A stirring paddle mounted next to the sample probe efficiently mixes each sample and, like the sample probe, is subjected to a rinse step at the rinse station. Sample mixing is configurable, via a software dashboard, to meet the challenge of more viscous oil samples.​
