Maintain Sample Integrity:
Our APS-7450V system ensures sample integrity by incorporating a drip cup that travels with the probe during its movement over the sample tubes. This innovative feature collects any sample droplets, preventing cross-contamination and preserving the accuracy of your results.

Sample Homogenization:
Achieving sample homogeneity is critical to obtaining reliable data. The APS-7450V employs a concussive mixing method, utilizing close proximity and high acceleration diluent addition. This technique is effective across a wide range of sample types, ensuring thorough sample mixing prior to analysis.

Customize Sample Routines:
Tailoring the analysis process to your specific requirements is made simple with the OilEase software. This intuitive software allows you to create custom methods and apply them to specific samples in a sequence, guaranteeing that the analysis method matches the sample type accurately.

Simplify Preparations:
The APS-7450V system offers a convenient onboard density correction option. This feature automatically adjusts the volume of sample diluent added, accounting for the density difference between standard and diluent solutions. By maintaining optimal speed while improving sample accuracy, it simplifies the preparation process and enhances overall efficiency.

Reduce Costs:
Built with durability in mind, the APS-7450V system ensures long and reliable performance with minimal routine maintenance. By reducing the need for frequent repairs and replacements, this instrument helps laboratories cut costs without compromising on quality.
