70Xi intellinostics
Built-in answers and operator information
Quick, responsive solutions — built-in alert messages give troubleshooting options to quickly solve problems
Self-guided tutorials — easy, on-screen instructions show how to use analyzer
In-depth system diagnostics — system checks verify performance and detect problems with critical components
Phase Technology 70Xi
Autosampler System
Automatic sampling & cleaning
Set-and-forget convenience set 1 to 48 test runs, 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 exact amount of sample
required by the ASTM method.
Self-cleaning Saves time and ensures perfect cleaning
every time. No more need for cotton swabs or risk of
damage to sample cup.
70Xi home screen
70Xi “Favorites” feature
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
Built-in tools to validate test results
Overlay and compare multiple phase plots
Control and trend charts Automatic QC run Option to retest sample Optional alert or lockdown if out of
acceptable limits
70Xi control chart – consistent runs
70Xi control chart – bad run
70Xi plot overlay – consistent runs
70Xi plot overlay – bad run

POUR POINT ASTM Method Comparison
ISL/PAC CPP5Gs The CPP5GS is extremely slow and has poor
precision – uses a mechanical tilt method which takes 80 – 140 minutes to complete a pour point test
Compare to Phase Technology pour point test takes 8 – 20 minutes
ISL/PAC MPP5Gs The ISL MPP5Gs uses ASTM D7346 to determine the “no
flow” point of petroleum products. ASTM stated that there is no correlation between no flow and pour point.
ASTM D7346 no flow point cannot be used to certify lube oil products for release because it is not a pour point method. The only accepted standards for product release are pour point methods, such as ASTM D5949 (as used by Phase Technology 70Xi analyzers).
POUR POINT ASTM Method Comparison
Tanaka MPC-102 Tanaka is the slowest automatic method
reports of 90 – 120 minutes for low temperature lubes Phase Technology 70Xi can perform at least eight test
runs in the time that it takes Tanaka to perform one single test!
The MPC-102 requires 4 mL of sample (contrast to Phase Technology use of 0.15 mL). Larger sample volume introduces non-uniform temperature.
Even with external liquid cooler, MPC-102 is not able to reach the low temperature level that Phase Technology does. Tanaka is only capable of going down to -30°C
with internal cooler Phase Technology reaches -88°C with internal
cooler

FREEZE POINT ASTM Method Comparison
ISL/PAC takes 2 to 3 times longer to run a freeze point test compared to Phase Technology
ISL/PAC FZP52Gs freeze point analyzer has serious false warming issues• Numerous studies have shown high
incidence of false warming – as high as 60% in a BP study
• Shell Bulletin GLN 33a (September 14, 2006) warned that ISL “can occasionally falsely show a failure if samples contain small amounts of high boiling point material”
The Phase Technology ADVANTAGE:
Phase Technology’s 70Xi analyzer is 4 to 10 times faster than the competition!
Phase Technology’s 70Xi analyzer has the world’s best precision
The 70Xi requires much less sample: 4 to 14 ml less needed per test!
The Phase Technology ADVANTAGE:
Phase Technology has the oldest, most established, continuous-in-production automatic cold flow ASTM Methods – 17 years of proven, in-the-field use!
The PSA-70Xi tests pour, cloud and freeze point in one single unit. You’d have to buy two or three separate analyzers from our competitor!
Thank you!
