70Xi - Combined cloud, pour and freeze point lab analyzer

Phase Technology’s 70Xi cold flow properties analyzer significantly increases lab productivity and improves profitability by providing quick, precise results. The 70Xi analyzer helps minimize giveaway and ensure that released product is on spec.

Phase Technology users can be confident that their test results accurately meet and comply with ASTM International standards for pour, cloud and freeze point: ASTM D5949, D5773 and D5972.

The PSA-70Xi is the world’s only analyzer that performs pour, cloud and freeze point in one unit. And, it’s the only analyzer that has factual, valid ASTM methods for all three methods.


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

Easy-to-use interface – New colorful graphic icon buttons for faster navigation. Intuitive and easy to understand on-screen prompts. Greater use of touch screen gestures and commands. More responsive keyboard.

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
