Antifreeze Engine Coolants

Scientists at Phase Technology have dedicated many years of research in the low temperature phase transition behavior of materials. Their expertise, in combination with the latest advances in electronic and cooler designs, has led to patented technologies that measure the freeze point of engine coolant precisely. 

These unique proprietary technologies offer distinct advantages over other methods in terms of precision, speed, reliability, compactness and ultra-low sample temperatures. The net result is the FPA-70XAF, a compact instrument that accurately reports the freeze point of engine coolants. The methodology was adopted by ASTM D6660 and specified in coolant specifications for light and heavy-duty vehicles such as ASTM D3306, D4985, GM6277M and Ford WSE-M97B44-B. 

Coolant manufacturers, packagers, research and inspection laboratories, government agencies and many other facilities derive significant benefits from using Phase Technology's freeze point analyzers. In comparison with the manual D1177 method, the analysis time is reduced to less than 10 minutes while precision is significantly improved.

Food Industry Applications

Applications in the food industry include many standard test methods used by the American Oil Chemist Society (AOCS) and the Association of Official Analytical Chemists (AOAC).

Our analyzers can be configured to perform tests such as Titer, cloud and melting points, winterization, nucleation and cold properties of oils and fats. 

Beyond the detection of phase transition temperatures, Phase Technology test instruments provide additional information such as the relative extent of phase separation. This is useful in indicating the extent of melting, crystallization or immiscibility at different temperatures.

Household and Industrial Cleaners; Personal Care Products

Surfactants find multitudes of usage in household detergents, personal care products, industrial cleaners and industrial processing. One particular type, the nonionic surfactants, is subject to a formation of a new surfactant-rich phase usually at an elevated temperature called the cloud point. The cloud point then, is the temperature at which a surfactant becomes insoluble in water as the sample is warmed. This parameter is important, for example, when designing detergents for use in hot water.

Gel point is the temperature at which the sample experiences an abrupt reduction in flow characteristics due to gelation. Phase Technology’s proprietary method disturbs the sample with a precisely-defined force at 3°C intervals (or any other user programmable interval) until movement subsides suddenly. With its advanced optical system, Phase Technology’s gel point analyzer is ideal for consumer products such as hair gel, as well as gelatin and medical agarose, for which gelling behavior is important.

Plastic and Resin Polymers

The characterization of plastic/resin polymers in solvent mixtures is important during their production and finished states. Phase Technology analyzers can be used to elucidate the phase transitions in these samples. The temperature range under which the samples are transformed from being clear to cloudy, opaque, or otherwise precipitate out of the solution mixture may be clearly delineated.
