High performance sample handling, precise sample injection, and built-in automatic cleaning — the 70Xi Autosampler Analyzer System gives you a full range of robust, productivity-boosting features that eliminate human error and decrease lab analysis time.

Phase Technology’s 70Xi Autosampler Analyzer Systems give you unmatched versatility and performance as they provide unattended operation for round-the-clock sample analysis.

The 70Xi’s 48-station autosampler lets lab personnel run multiple samples without the need to individually pipette, set and verify analyzer options or wait for test results.


  • Best overall precision of any automatic or manual method
  • Fastest speed of any cloud, pour or freeze point analyzer: test results in just 8-20 minutes
  • Easy-to-use and versatile: saves time in the lab, no special training needed

  • Set-and-forget convenience — unattended testing lets you initiate 1 to 48 runs in a row, then walk away and let the analyzer do the rest!
  • Automatic sample injection — no need to individually pipette samples or change pipette tips. Always uses the precise amount of sample required by the ASTM method.
  • Self-cleaning — saves time and headaches caused by manual cleaning. No more need for cotton swabs or risk of damage to sample cup.
  • Unlimited flexibility – change sample order without stopping current test run. Perfect for shifting, “need-this-now” priorities.
  • Task consolidation – reduced need for manual intervention, frees up staff resources
  • High-throughput sequencing – avoid bottlenecks in workflow
  • Self cleaning –automatic rinse and flush
  • Less operator involvement – greatly reduced chance of user-introduced error; automation for fewer data entry errors
  • Powerful cooling system; minimum sample temperature improvement to below -88°C [-126°F]
  • One-touch preset Favorites – Frequently-used test settings can be stored in the analyzer for quick access. Favorites can be created, organized, sorted or deleted as you desire. With the single push of a button, lab operators can efficiently perform tests in significantly less time.
  • Full-color, touch-sensitive, 15” high resolution screen – Easier to read and view more information. Multitasking capability eliminates need to flip between multiple windows. Displays several views of information at the same time. Overlay and compare multiple phase plots in different colors
  • USB and Ethernet connectivity – Quickly export analyzer data to a portable USB flash drive. USB capability also makes remote diagnostics and troubleshooting easier. Easily connect other devices like printers, barcode scanners and keyboard. Ethernet port available for connecting to LIMS or internal computer network
  • Optimized for quality control applications – Automatic QC runs with instantaneous control charts. Trend charts with “touchable” data points that open individual phase plots. Retest sample option increases confidence in result; optional alert or lock down if out of acceptable limits
  • Robust design and improved serviceability – New modular component design. Field-replaceable parts (including cooler). Easier, faster service without the need to re-calibrate
  • Capable of any user programmable resolution to 0.1°C
  • Unsurpassed detection of contamination in jet fuels
  • Programmable user access levels streamlines workflow and prevents accidental changes
  • Alert sounds when test is finished and ready for next run; audible keyboard “clicks”
  • Connect any HP (or PCL compatible) printer via USB
  • Import and store any user documents (.doc, .pdf, .ppt and .pps) for customized operating procedures (SOP) or training
  • Configurable desiccant replacement count
  • Customizable reporting – test history, plot data and self-diagnostics can be displayed on-screen, printed, or transferred to computer for statistical analysis, presentations, email sharing, archival storage
  • Completely self-contained system: no need for external coolant
  • Quiet, energy efficient and environmentally friendly (no toxic coolant vapors)
